Description

Continuous galvanizing production line light complete machine roller bearing seat guide wheel

Technical Field

The utility model relates to a continuous galvanizing production line light complete machine roll chock guide pulley belongs to cold rolling equipment technical field.

Background

The bearing seat of the working roll of the finishing machine of the continuous galvanizing production line is used for fixing and supporting a bearing, and simultaneously, the position of the roll in the housing of the finishing machine is controlled to ensure stable operation and rolling precision, so that the guiding accuracy and stability are very important. And guide wheels are arranged on two sides of the bearing seat and used for enabling the bearing seat and the roller sleeve set to smoothly enter the finishing machine housing. The existing guide wheel adopts a cylindrical roller bearing with the model number INA NUTR50, a large number of rolling bodies are contained in the bearing, the thickness of the outer ring of the bearing is only 8mm, and the impact strength is insufficient. In the process of guiding in and guiding out the bearing seat and the roller sleeve, the guide wheel bears the gravity of the roller and the bearing seat sleeve which can reach more than 4800KG, the guide wheel is in contact with the guide rail in the hoisting process of the roller and the bearing seat sleeve and directly bears the impact load of more than 5t, and the outer ring is extremely easy to knock and break, so that the spare parts are scrapped, and the cost of the spare parts is increased; the damaged guide wheel bearing is continuously used for guiding in and guiding out, the guide wheel bears the gravity of the roller and the bearing seat sleeve set, potential safety hazards and production hazards exist, and even the roller replacement cannot be completed due to the damage of the bearing, so that the production is influenced. Therefore, the roller bearing block guide wheel of the photo-finishing machine on the continuous galvanizing production line is required to be designed to replace the existing bearing, meet the use requirement, reduce the loss and reduce the cost of spare parts.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a continuous galvanizing production line light complete machine roll chock guide pulley is provided, replaces current bearing, satisfies the operation requirement, reduces the loss, reduces spare part cost.

The technical scheme of the utility model is that:

the utility model provides a continuous galvanizing production line light complete machine roll chock guide pulley, includes shaft, gyro wheel, gasket and spacer ring, the spacer ring is ring shape, the shaft is the ladder cylinder axle, and the one end that the shaft diameter is the biggest is the fixed axle, links to each other with the fixed axle and is the pivot, and the shaft center is provided with the through-hole mounting hole, be equipped with the centre bore in the middle of the gyro wheel, one end terminal surface is provided with the fixed slot, and the other end terminal surface is provided with the gasket groove, centre bore and shaft phase-match, the fixed slot and fixed axle phase-match, the gasket groove and gasket phase-match, the spacer ring hole.

The axial length of the rotating shaft is 0.5-0.8 mm larger than the width of the central hole.

The material of shaft, gyro wheel, gasket and spacer ring is 45# steel.

The wheel shaft, the roller, the gasket and the spacer ring are assembled together in a clearance fit mode, the bearing seat is inserted into the end with the smaller diameter of the wheel shaft, the bolt is fixed to the bearing seat through the mounting hole, the relative positions of the wheel shaft, the roller, the gasket and the spacer ring are fixed in the using process, and the gasket is arranged between the roller and the spacer ring and can be prevented from being locked in the running process of the roller and the spacer ring.

The utility model has the advantages that: the utility model discloses simple structure, simple to operate have solved the not enough defect of gyro wheel bearing intensity, and shock resistance and bearing capacity improve greatly, can satisfy the field usage requirement, reduce accident frequency, reduce cost simultaneously.
