Belt wheel tensioning device for crushing and screening equipment

Abstract

The invention discloses a belt wheel tensioning device for crushing and screening equipment. The belt wheel tensioning device is characterized in that a tensioning wheel assembly is arranged on an installing base through a connecting rod assembly, a wheel train axial long round hole and an adjusting jackscrew are arranged at the joint position of the installing base and the connecting rod assembly, an arc-shaped long round hole, the adjusting jackscrew and a positioning plate are arranged at the joint position of the connecting rod assembly and the tensioning wheel assembly, one end of the tensioning wheel is arranged to a tensioning wheel installation base in a hinged mode, a tensioning wheel adjusting jackscrew is arranged at the joint position of the other end of the tensioning wheel and the tensioning wheel installation base, and a buffering assembly is further arranged between the tensioning wheel assembly and the installing base. According to the belt wheel tensioning device for the crushing and screening equipment, the axial position of the belt wheel and the axis angle of the belt wheel of the tensioning device can be adjusted through the adjusting jackscrew, the position of the tensioning wheel assembly can be adjusted in multiple directions, stepless adjustment is achieved, the adjusting process is simple, flexible and efficient, meanwhile, the tensioning wheel installation base can be clamped through the arranged positioning plate, the adjusting precision is guaranteed, adjustment difficulty is avoided, and adjustment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crushing and screening equipment, in particular to a pulley tensioning device for crushing and screening equipment. Background technique [0002] As an important working part of the belt transmission system, the tensioning device has a great influence on the working performance of the whole equipment. Belt transmission has the characteristics of simple structure, stable transmission, buffering and absorbing vibration, transmission of power between large shaft distances and multiple shafts, low cost, no need for lubrication, and easy maintenance. It is widely used in modern mechanical transmission. [0003] In the prior art, the driving wheel drives the driven wheel through a V-belt. The tensioning device lifts up the V-belt to tighten it, and the tensioning device presses down to relax the V-belt. Because the V-belt is long, there is a risk of deviation and wear of the V-belt at the position of the tens...

AI Technical Summary

Problems solved by technology

At present, the adjustment operation of the position and angle of the V-belt tensioning device is relatively cumbersome

If it is necessary to adjust the relative angle between the tensioning pulley and the pulley, the entire tensioning device needs to be adjusted, which is difficult to adjust and the adjustment accuracy cannot be guaranteed. Multiple adjustment tests are required, which is time-consuming and laborious

And it is impossible to adjust the position of the tensioning device in the direction of the axial position of the pulley
