Description

Driving chain wheel combined device

Technical Field

The utility model relates to a driving sprocket composite set belongs to agricultural machine trade technical field.

Background

Sprocket chain drive is agricultural harvesting machine's key part, also is the vulnerable part, and especially the mode and the reliability that the sprocket is connected with the transmission shaft cause the important hidden danger that needs to overhaul the change, and at present mostly the sprocket snap-on is on the transmission shaft, because drive power is big, often causes the transmission insecure, increases wearing and tearing to it wastes time and energy and influences agricultural machine result of use to change the sprocket.

Disclosure of Invention

In order to solve the above problem, an object of the present invention is to provide a driving sprocket assembly, be connected with upper jaw and lower jaw on driving sprocket, driving sprocket is connected with the chain and is transmitted power, upper jaw and lower jaw and input shaft input power, because driving sprocket and upper jaw and lower jaw use hexagon socket head cap screw connection, directly with the input shaft, so maintain and change simple and easy labour saving and time saving, upper jaw and lower jaw and input shaft, through keyway connection, hexagon socket head cap screw is fixed and further fasten through threaded through-hole, make firm in connection reliable, avoid becoming flexible to increase wearing and tearing, and service life is prolonged, and reliability is enhanced.

The utility model provides a technical scheme that its technical problem adopted is: the driving chain wheel combination device consists of a driving chain wheel, an upper jaw and a lower jaw, the driving chain wheel is connected with the upper jaw and the lower jaw through an inner spigot of the driving chain wheel and an upper jaw connecting disc of the upper jaw and a lower jaw connecting disc of the lower jaw respectively, the upper jaw and the lower jaw are connected with the driving chain wheel respectively through inner hexagonal bolts, an upper jaw tile mouth of the upper jaw corresponds to a lower jaw tile mouth of the lower jaw, and the upper jaw and the lower jaw are connected through the inner hexagonal bolts. The driving chain wheel is provided with an inner spigot, and the bottom surface of the inner spigot is provided with a threaded hole. The upper jaw is formed by integrally connecting an upper jaw connecting disc and an upper jaw tile opening, the upper jaw connecting disc is provided with a groove connecting hole A, and the upper jaw tile opening is respectively provided with a key groove, a thread through hole and a groove through hole. The lower jaw is formed by integrally connecting a lower jaw connecting disc and a lower jaw tile opening, a connecting hole B with a groove is formed in the lower jaw connecting disc, and a threaded connecting hole is formed in the lower jaw tile opening.

The utility model has the advantages that: the novel driving chain wheel and input shaft connecting device is suitable for various agricultural machines, is firm in connection, reduces maintenance cost, improves the operation reliability of the whole machine, meets the agricultural production requirements, and has wide popularization and application values.
