Description

A transmission tooth for clamping steel cables

technical field

The utility model relates to a transmission tooth, in particular to a transmission tooth used for clamping steel cables.

Background technique

When the existing clamps clamp the steel wire rope, they generally use sleeve fixing or rope clips, lock buckles or multiple combinations of clamping methods to squeeze the steel wire rope. The clamping force on the steel wire rope is limited, and sliding is prone to occur. Because insufficient clamping frictional resistance will cause the wire rope to slip or even fall off, the reliability of clamping and fixing is poor, and the shape and size of these clamping parts are not suitable for being designed as conveyor gears. The cable tooth structure and clamping method of the toothed cable conveyor lead to limited clamping force and short conveying distance. The structure of the connected material conveying components is complex and heavy, which is not suitable for conveyors with wide grooves, long conveying distances, and high conveying capacity. For larger working conditions.

One end of the side of the lower tooth block is provided with a bolt connection hole, and the other end is provided with a boss.

The utility model is a transmission tooth for clamping steel cables, which has the following technical effects:

1) By designing a V-shaped clamping hole on the lower tooth block and the upper pressure block, a smooth transitional bending part is formed, and the first lock is formed when the steel cable is clamped; along the inner wall of the clamping hole Multiple sets of tooth-shaped cross-sectional teeth are set in the direction of the cable axis, which are used to compress and fix the steel cable to form a second lock; the two locks ensure that the friction resistance of the steel cable is large after compression, and it is not easy to slip phenomenon, which can meet the working conditions that require greater cable traction, such as the working conditions of wider conveyor grooves, longer distances, and larger conveying volumes.

2) Reasonable structural design and diverse functions. The structure is the clamping member of the steel cable, the transmission member meshed with the gear, the connecting member of the scraper bracket and the scraper, and the scraper assembly and the steel cable running on the guide rail to prevent the scraper assembly from running off and drifting. The support member of the chain.

3) Small size, light weight, suitable for batch forging production, good economy.

4), easy to install, easy to replace, easy to operate and maintain.
