I. Iteration of Tooth-Type Braking Technology, CKB Tooth-Type Power Failure Brake Achieves Industrial Application
Industrial heavy-duty transmission and precision positioning lifting equipment have continuously increasing requirements for parking locking force, power failure safety, and anti-slip ability. Conventional friction-type power failure brakes rely on frictional engagement for braking, and in heavy-duty conditions, they are prone to slipping and significant attenuation of static locking torque, making them difficult to meet the safety operation requirements of lifting, rotating, and precise positioning equipment. Based on the tooth meshing engagement braking principle, CKB tooth-type power failure brake distinguishes from traditional friction braking structures and adopts an internal and external tooth interlocking locking mode. It belongs to the category of normally closed power failure safety brakes. When energized, it attracts the moving tooth disk and disengages the internal and external teeth, allowing the transmission shaft to operate freely without resistance. When powered off, it uses the spring to engage the teeth and brake, balancing large locking torque, anti-slip, wear resistance, and compatibility with high and low voltage electronic control features. It fills the gap of heavy-duty slipping in friction brakes and is suitable for automation lifting, CNC turntables, three-dimensional transmission, and material lifting industrial equipment.
Currently, the control standards for industrial special equipment have been upgraded. In the event of sudden power failure or line faults, the equipment must lock instantly to avoid shaft slippage, falling loads, and position deviation risks. The CKB tooth-type power failure brake is compatible with industrial AC and DC dual-voltage electronic control. It has a strong structural rigidity and no slippage during braking. Its static parking stability is superior to that of ordinary friction brakes. It is suitable for the lightweight transformation of new and old heavy-duty equipment and takes into account operational efficiency, running safety, and long-term maintenance. It has become the mainstream component for heavy-duty transmission braking upgrades.
II. Structural Braking Principle, Core Construction Analysis of CKB Tooth-Type Power Failure Brake
The CKB tooth-type power failure brake adopts a modular integrated structure. It is mainly composed of an excitation coil, pressure spring, high-precision meshing tooth disk, guiding clutch component, sealed dust-proof housing, and manual release mechanism. The braking logic follows the industrial failure safety design standard. When the equipment is powered on, the electromagnetic coil generates magnetic force, overcoming the spring elasticity and driving the moving tooth disk to move. The internal and external teeth are completely separated, allowing the transmission shaft to operate freely without resistance. The equipment can perform normal start-up and shutdown operations.
In the event of power failure, line breakage, or emergency shutdown, the magnetic force rapidly dissipates, and the pressure spring quickly pushes the moving tooth disk to engage with the fixed tooth disk. The teeth are completely meshed and locked to the shaft, achieving rigid locking braking. Compared to friction braking that relies on friction for parking, the tooth meshing is a mechanical hard limit, without friction slipping or torque attenuation issues. It also comes with a manual release device, allowing for manual disengagement of the teeth during maintenance with power off, facilitating equipment disassembly for debugging and fault reset, and reducing the difficulty of equipment maintenance and repair.
III. Core Performance Advantages of CKB Tooth-Type Power Failure Brake Compared to Friction Brakes
Rigid tooth engagement, no slippage in heavy-duty conditions. Using hardened precision tooth disks for meshing braking, the locking torque per unit volume is higher, and it has stronger bearing axial and radial heavy-duty load capacity. The parking of lifting and rotating position equipment has no micro-slippage, stable positioning accuracy, and is suitable for high-precision point locking of CNC turntables and three-dimensional lifting equipment, avoiding the problem of workstation misalignment caused by friction braking slipping.
Lower wear and tear, extended overall maintenance cycle. There is no large-area friction consumable wear and loss. The braking relies on the mechanical meshing of teeth instead of frictional loss braking. Daily operation has no consumable grinding consumption. The tooth disk is hardened by high-frequency quenching, with strong resistance to compression and deformation. Long-term start-stop braking wear is minimal, and there is no need to frequently replace friction plates. This significantly reduces the frequency of equipment disassembly and maintenance, and lowers the cost of component procurement and manual maintenance.
Stable response speed, wider application range of working conditions. The power failure engagement response is rapid, the spring elasticity is balanced and controllable, and the braking action is not delayed in high and low temperature environments. It is suitable for low-temperature and high-temperature alternating working conditions in workshops. The entire machine is equipped with a sealed casing and a dust-proof sealing structure, which prevents iron filings, dust, and moisture from entering the gear meshing chamber. It is suitable for harsh working conditions such as machine tool processing, metallurgical workshops, and outdoor lifting operations. The gear teeth are less likely to get stuck or rusted, and the operation failure rate is controllable.
It is compatible with dual-channel electrical control and has strong installation versatility. The CKB gear-type power failure brake is compatible with industrial 24V DC and 380V AC conventional electrical control. No additional complex power conversion and rectification components are required. The standardized installation dimensions of the flange make it suitable for installation at the tail of the motor, the input end of the reducer, and the rotating transmission shaft at multiple positions. Old equipment can be directly replaced without modifying the transmission base and control lines. The transformation is convenient and straightforward.
There is sufficient safety redundancy, and it is suitable for the acceptance of special equipment. Pure mechanical gear locking is not affected by minor voltage fluctuations. In the event of sudden power failure or line faults, it can stably brake. It comes with a manual release structure to meet the safety standards for special equipment maintenance in lifting, parking, and numerical control. It successfully passes the equipment annual inspection and verification, and is suitable for the regular compliance operation of special equipment.
Four. Segmented Adaptation Scenarios, Meeting the Heavy Load Transmission Requirements of Multiple Industries
Lifting and hoisting equipment: portal small cranes, material elevators, vertical conveying equipment, relying on the CKB gear-type brake to lock the lifted load when power is lost, preventing the falling and sliding of heavy objects, improving the safety of high-altitude operations, and suitable for heavy-load lifting operations in factory areas and construction sites.
Numerical control precision equipment: rotary turntables of machining centers, indexing transmission machines, relying on the gear-type non-slipping brake to ensure precise positioning of the processing station, improving the consistency of workpiece processing, suitable for locking operations at precision mechanical processing stations.

Metallurgical non-standard transmission: metallurgical rollers, building material rotary machinery, with a lot of dust and impurities in the workshop, the gear-type sealed structure has strong resistance to interference from impurities, and the braking is stable. It is suitable for continuous production operations in harsh workshops.
Five. Key Points of Use and Maintenance and Industry Development Value
Daily maintenance mainly focuses on inspection and protection. Regularly clean the external dust and debris of the brake, and check the sealing of the connection port. Avoid operating beyond the rated load to prevent the gear disk from being squeezed and deformed. Regularly manually disengage the gear disk when the equipment is stationary to ensure smooth meshing and avoid rusting and jamming of the gear teeth. Currently, the CKB gear-type power failure brake is standardized for mass production, with uniform control of gear disk precision and spring parameters. Batch products have balanced braking performance, suitable for batch equipment for use.
Industrial braking is gradually upgrading from frictional type to rigid gear meshing type. Heavy load, high precision, and low maintenance have become the direction of component iteration. The CKB gear-type power failure brake relies on high locking, low loss, and high safety characteristics to solve the problems of heavy load slipping and consumable wear of traditional friction brakes, helping industrial transmission equipment improve quality and reduce costs, and adapting to the long-term safe development of intelligent manufacturing and special equipment industries.
