The clamping hole is integrally V-shaped, U-shaped or S-shaped along the length direction.
The cross sections of the first arc-shaped groove and the second arc-shaped groove are semicircular.
The inner surfaces of the first arc-shaped groove and the second arc-shaped groove are uniformly distributed with tooth groups along the axial direction.
One end of the side face of the lower tooth block is provided with a bolt connecting hole, and the other end of the side face of the lower tooth block is provided with a boss.
The utility model relates to a transmission gear for clamping a steel cable, which has the following technical effects:
1) The V-shaped clamping holes are designed on the lower tooth block and the upper pressing block, so that a smooth transition bending part is formed, and a first locking is formed when the steel cable is clamped; a plurality of groups of teeth with tooth-shaped cross sections are arranged on the inner wall of the clamping hole along the axial lead direction of the steel cable and are used for compressing and fixing the steel cable to form a second locking; the two locks ensure that the friction resistance is large after the steel cable is pressed, the slipping phenomenon is not easy to occur, and the working condition that the traction force of the steel cable is larger can be met, such as the working condition that the groove of the conveyor is wider, the distance is longer and the conveying capacity is larger.
2) And the structure design is reasonable, and the functions are various. The structure is a clamping component of the steel cable, is also a transmission component meshed with the gear, is a connecting component of the scraper bracket and the scraper, and is a supporting component for the scraper assembly and the steel cable to run on the guide rail and prevent the scraper assembly from deviating and drifting.
3) The die has small outline dimension, light weight, suitability for mass forging production and good economy.
