Abstract
The invention provides a thrust bearing for a high-power high-voltage dry motor, and belongs to the technical field of manufacture of bearings. The thrust bearing structurally comprises an upper thrust bearing block, an upper slide plate panel, a slide plate, a lower slide plate panel, a lower thrust bearing block and a thrust bearing pedestal, wherein the lower thrust bearing block is arranged on the thrust bearing pedestal, the upper slide plate panel and the lower slide plate panel are respectively arranged on the upper and lower surfaces of the slide plate, the lower slide plate panel is arranged on the lower thrust bearing block, and the upper thrust bearing block is arranged on the upper slide plate panel. The thrust bearing for the high-power high-voltage dry motor is reasonable in design and simple in structure, and as the part effectively solves the problem of residual axial force of an electric pump on the motor, the reliability of the electric pump and the motor is guaranteed, so that the service lives of the electric pump and the motor are prolonged.
Description
Technical field
The present invention relates to a kind of bearing unit, specifically with the high-power high-voltage dry Series Motors thrust bearing in order to eliminate the residue axial force produced when electric pump works of high pressure dry electric drilling match, this bearing can improve the working life of motor and electric pump greatly.
Background technique
At present, motor employing low pressure (660V/1140V) motor that the mining submersible electric pump that underground coal mine uses is supporting, its match power is mostly at 300 below kW.Along with the increase of underground coal mine water yield, the frequent generation of infiltration accident, the required motor power (output) supporting with mining submersible electric pump of underground coal mine is increasing.In this case, the axial force that during electric pump work, electric pump produces motor is also increasing.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, provides a kind of high-power high-voltage dry Series Motors thrust bearing.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of high-power high-voltage dry Series Motors thrust bearing, comprise thrust shaft supporting block, upper slide panel, slide plate, lower skateboard panel, lower thrust shaft supporting block and thrust shaft block, described lower thrust shaft supporting block is arranged on thrust shaft block, upper slide panel and lower skateboard panel are separately positioned in the upper and lower surface of slide plate, lower skateboard panel is arranged in lower thrust shaft supporting block, and upper thrust shaft supporting block is arranged on upper slide panel.
The working state of thrust bearing is lubricated in oil, selects the high-abrasive material of pairing, and compatiblely with machinery oil become a difficult problem.Through test of many times, match effect with Babbitt and 40Cr better.Determine that upper thrust shaft supporting block and lower thrust shaft supporting block all adopt 40Cr, upper slide panel and lower skateboard panel all adopt Babbitt.
Fit up gap between described upper thrust shaft supporting block and upper slide panel is between 0.7-1.5mm.
Compared with prior art, the beneficial effect produced is a kind of high-power high-voltage dry Series Motors thrust bearing of the present invention:
The present invention is reasonable in design, and structure is simple, because these parts effectively solve the residue axial force that electric pump produces motor, ensure that the reliability of electric pump, motor, thus extends the working life of electric pump, motor.
