Composite cold pressing, synthesizing and cementing carrier roller

Abstract

The invention discloses a composite cold pressing, synthesizing and cementing carrier roller which comprises combination sealing devices, a pipe base, check rings, bearings, spacer rings and a shaft. The shaft penetrates the pipe base, the spacer rings and the bearings are arranged at the two ends of the shaft, and the bearings are fixed to the two ends of the shaft through the check rings. The combination sealing devices penetrate the shaft to be in interference connection with the pipe base to be arranged at the two ends of the shaft. The pipe base is formed by connecting a pipe and bearing pedestals into a whole in a cold pressing, synthesizing and cementing manner, the pipe is made of a straight-line electric welding steel pipe special for an ultrahigh-precision carrier roller through inner and outer pipe rust prevention treatment. The bearing pedestals are made of polyformaldehyde through one-time injection moulding. The production procedure of the bearing pedestals is simplified, the precision of the finished bearing pedestals is improved, the weight is low, and strength is high; and the assembling mode of the bearing pedestals and the steel pipe is simplified, noise is lowered, and the carrier roller is applied to the field of bulk material conveying equipment.

Description

technical field [0001] The invention relates to a composite cold-pressed synthetic glue joint idler in the field of bulk material conveying equipment. Background technique [0002] At present, the idler is the key component of the belt conveyor, the weight accounts for about 30% of the weight of the whole machine, the price accounts for about 20%-30% of the whole machine, and the amount is huge. Low resistance, energy saving, etc. have become the main direction of the development of idlers. However, the existing idler has the following three deficiencies: (1) The tube seat of the existing idler is processed with a tube car stop, the bearing seat is rounded, and the tube and the bearing seat are assembled and welded together to form a tube seat. This kind of tube seat The processing method has many shortcomings such as many processing steps, high energy consumption by welding, inaccurate positioning, and poor coaxiality. (2) The existing idler adopts cold stamping bearing s...

AI Technical Summary

Problems solved by technology

[0006] The process of cold-pressing synthetic bonding is to use special equipment to cut the pipe to meet the requirements of cutting length, and make an interference connection with the polyoxymethylene bearing seat formed by injection molding at one time. A is bonded with adhesive glue to play the role of adhesion, tear resistance, mechanical vibration resistance, impact resistance and sealing. The application of this process solves the problem of firm connection between the steel pipe and the engineering plastic bearing seat. Meet the strength requirements of the connection between the tube of the idler and the bearing seat, and avoid the welding problem between the steel tube and the stamped bearing seat;
