Abstract

The invention provides an axial positioning device of a crushing roller, which relates to a crushing machine and solves the problems that in the prior art, the installation and the maintenance of the crushing roller are difficult, and the equipment operation reliability is poor. The axial positioning device comprises high-strength locking screw nuts, a plurality of high-strength round head propping and pushing screws and two high-strength propping and pushing gaskets, wherein the circumferential rings of the two end surfaces of the high-strength locking screw nuts are provided with a plurality of threaded holes, the two locking screw nuts are respectively matched and connected with external screw threads of the fixing end and the floating end of a roller shaft, one propping and pushing gasket is arranged between the locking screw nuts and a bearing arranged at the floating end, the other propping and pushing gasket is arranged between the locking screw nuts and a No. IV isolation ring, and the round head propping and pushing screws are connected with the threaded holes arranged on the end surfaces of the locking screw nuts. The axial positioning device is used for the axial positioning of the crushing roller of a double-tooth roller crushing machine, the service life of parts can be prolonged, in addition, the installation and the maintenance can be conveniently and fast carried out, and the production efficiency of equipment is greatly improved.

Description

technical field [0001] The invention relates to a crusher, in particular to an axial positioning device for a crushing roller of a double toothed roller crusher. Background technique [0002] As the core equipment of the mobile crushing station and semi-mobile crushing station in the semi-continuous mining process system of large open-pit mines, the double-toothed roller crusher is widely used in mines. Such as figure 1 As shown, the body of the double-toothed roller crusher mainly includes two parts: a crusher box assembly 1 and a pair of symmetrically arranged crushing rollers 2 . [0003] When the double-toothed roller crusher processes hard materials, due to the randomness of feeding and the helical teeth, only one or two pairs of teeth are performing crushing operations. The crushing rollers not only have to bear huge radial loads, but also It has to bear a huge axial load, and due to the uncertainty of the position of the hard material on the crushing roller, the axi...
