Gear tooth type crusher tooth roller

Abstract

The invention relates to a toothed roller of a gear-toothed crusher, comprising a main shaft, a self-aligning roller bearing, a tooth plate, and a hexagonal cylinder. Connect the transmission, the tooth plate is fastened to the hexagonal cylinder with bolts through T-shaped slots; a signal generator is installed on the shaft end retaining ring at one end of the main shaft, and a signal receiver is installed on the blind cover outside the spherical roller bearing , when the main shaft rotates, the signal generator and the main shaft rotate together, while the signal receiver on the cover is relatively stationary relative to the main shaft, and the rotational speed of the main shaft is measured. The present invention changes the tooth roller structure of the gear-tooth crusher into a split type, which is convenient for replacement and maintenance, has a simple and reasonable structure, and reduces manufacturing costs; at the same time, it has a safety detection device, which plays the role of overload protection and enhances the safety and reliability of work. .

Description

technical field [0001] The invention belongs to the field of crusher structure design, and in particular relates to a toothed roller of a gear-toothed crusher. Background technique [0002] The gear tooth crusher is based on the principle of shearing and crushing of materials, combining high torque, low speed and special tooth shape to obtain specific product particle size. With the further improvement and maturity of modern crushing theory, the requirements for domestic crushers will become higher and higher: high safety and reliability, high degree of automation; modular design, reasonable and compact structure, and easy maintenance. [0003] Since there are still many integral tooth plates on the market, when the crushing tooth breaks, it needs to be replaced and repaired as a whole, which not only increases the maintenance cost but also reduces the work efficiency. There are also some machines due to the lack of overload protection, when the hard objects are broken, the...

Problems solved by technology

[0003] Since there are still many integral tooth plates on the market, when the broken tooth breaks, it needs to be replaced and repaired as a whole. Not only the maintenance cost is high, but also the work efficiency is reduced.

In some machines, due to the lack of overload protection, when crushing hard objects, the crushing teeth are forced to break, but the machine is still running, and the life of the machine is reduced.
