Description

TECHNICAL FIELD

[0001] The utility model belongs to toothed roll crusher technical field, concretely relates to a toothed roll crusher shaft coupling connecting structure. BACKGROUND

[0002] In industrial production, toothed roll crusher is a kind of equipment widely used in mining, metallurgy, building materials and other fields, mainly used for crushing high-hardness materials, such as ore, coal, limestone, etc. Toothed roll crusher crushes materials by extruding and shearing through two relatively rotating toothed rolls, so as to realize crushing effect. As a key component in the transmission system of toothed roll crusher, shaft coupling is mainly used to connect motor and main shaft of crusher, transmit power and compensate certain axial, radial and angular deviation.

[0003] However, the existing shaft coupling connecting structure is mostly rigid connection. When toothed roll crusher crushes hard materials, toothed roll may be subjected to a large impact force instantaneously, and this impact force will be transmitted to the shaft coupling through the main shaft, causing the shaft coupling to bear hard torsional force. Hard torsional force is easy to cause the elastic elements (such as rubber pad, spring, etc.) of the shaft coupling to fatigue or damage prematurely, and even cause the whole shaft coupling to fail. Although some elastic elements (such as diaphragm, high-torque spiral spring and shock-absorbing shaft coupling) have a certain buffering effect on the shaft coupling, these elements mainly rely on elastic reset after torsion, do not have continuous rotation buffering function, and are easy to cause damage to the buffering components, thereby affecting the use of toothed roll crusher.
