Problems solved by technology

Since the front and rear end faces of each sprocket are usually flat (such as the sprocket of a marine hatch cover), and the edge of the chain is arc-shaped, the fit between the two is poor, so the chain is easy to slip from the sprocket during operation. Slipping on the top not only leads to the failure of normal and continuous work, but also requires frequent post-maintenance, resulting in a decrease in work efficiency, and is also very dangerous and prone to accidents

Embodiment Construction

[0016] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0017] A sprocket with the function of preventing tooth jumping comprises a wheel disc 2, an axis hole 3 is formed on the axis of the wheel disc, and a keyway can be formed in the axis hole. On the outer surface of the wheel disc, a multi-circle sprocket 1 is made at intervals, and its quantity is not limited.

[0018] The innovation point of the present invention is that: the front end and the rear end of each chain tooth all make an anti-skid groove, and the shape of the anti-skid groove coincides with the shape of the edge of the chain, so as to prevent the chain from slipping off.

[0019] When the sprocket has two turns, an anti-skid groove is formed at the front end and the rear end of the inner surface of each sprocket.

Abstract

The invention relates to a sprocket with a function of preventing tooth slipping. The sprocket comprises a wheel provided with a shaft hole in the axial center. The outer surface of the wheel is provided with a plurality of circles of chain teeth at intervals. Both the front and rear ends of each chain tooth are provided with antislip grooves. The sprocket is reasonable in design, simple in structure, easy to produce, convenient to use and highly practical; tooth slipping can be avoided in use of the sprocket; normal operation of a chain is guaranteed; dangerous accidents are prevented; safety of a user is ensured; the sprocket is especially suitable for pulling a hatch of a vessel.

Description

technical field [0001] The invention relates to the field of sprockets, in particular to a sprocket with the function of preventing tooth skipping. Background technique [0002] A sprocket wheel is a commonly used mechanical part, which usually includes a wheel disc with a shaft hole formed on the center of the shaft, and a plurality of rows of sprocket teeth are evenly distributed on the outer surface of the wheel disc. Since the front and rear end faces of each sprocket are usually flat (such as the sprocket of a marine hatch cover), and the edge of the chain is arc-shaped, the fit between the two is poor, so the chain is easy to slip from the sprocket during operation. The upper slippage not only leads to the failure of normal and continuous work, but also requires frequent post-maintenance, resulting in a decrease in work efficiency, and is also very dangerous and prone to accidents. Contents of the invention [0003] The object of the present invention is to overcome...
