Hydraulic axial plunger type transmission roller with reverse stop and speed-regulating functions

Abstract

The invention discloses a hydraulic axial plunger type transmission roller with reverse stop and speed-regulating functions. The hydraulic axial plunger type transmission roller comprises reverse stopstructures arranged inside radial plate bearing seat structures and a roller driving device arranged between two radial plates. The roller driving device comprises a supporting body, steel balls, a swashplate, a rotating disc, plungers, cylinder bodies and an oil distribution disc. A shaft oil inlet and a shaft oil outlet are formed in a roller shaft. According to the hydraulic axial plunger typetransmission roller with the reverse stop and speed-regulating functions, radial component force of reacting force generated by the rotating disc to the plungers under extrusion of the plungers is utilized to generate rotating torque for the rotating disc, then the rotating torque pushes a roller body to rotate through the cylinder bodies which are circumferentially mounted on the inner surface of the roller body in an evenly distributed mode, on the one hand, the internal space of the roller body can be fully utilized, on the other hand, the mode that working pressure oil flows in and flowsout in the axial direction of the roller shaft is adopted, thus an extra transmission device mounting space does not need to be arranged, mounting and maintaining are facilitated, and the hydraulic axial plunger type transmission roller is especially suitable for a high gassy mine or a belt conveyor without the arrangement space for a transmission device.

Description

technical field [0001] The invention relates to a driving roller for a belt conveyor, in particular to a hydraulic axial plunger driving roller with backstop and speed regulating functions suitable for belt conveyors in underground mines, on the ground, in ports and wharves, etc. , Belongs to the technical field of belt conveyors. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in various industries such as machinery, electronics, tobacco, injection molding, post and telecommunications, printing, and food. Belt conveyors can be divided into heavy belt conveyors such as mining belt conveyors according to their conveying capacity, and light belt conveyors such as those used in electronic plastics, food light industry, chemical and pharmaceutical industries. Belt conveyor is a kind of machinery that is driven by friction to transport materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller...

AI Technical Summary

Problems solved by technology

This traditional belt conveyor transmission needs to be installed on the side of the drive roller. For heavy-duty belt conveyors such as mine belt conveyors, the huge drive motor and reducer not only need to occupy additional installation space, but also for space The narrow coal mine underground coal transport roadway needs additional excavation of the installation and maintenance space of the transmission device, and it is necessary to ensure the coaxial installation of the reducer output shaft and the transmission drum during the installation process, and the installation and debugging are more complicated; in addition, due to the explosion-proof Particularity, the drive motors used in traditional mining belt conveyor transmissions need to use explosion-proof motors, which not only increases the production cost, but also increases the maintenance cost of supporting facilities (the use of high-power explosion-proof motors requires higher voltage grade)
