Abstract
The utility model discloses a device for disassembling a bearing of a motor, and relates to the field of motors. 3 to 8 internal threaded holes are formed in an internal bearing cover (4); two arc-shaped cushion blocks (3) are arranged between an inner ring of a bearing (2) and the internal bearing cover (4); a steel wire (6) is bound outside the arc-shaped cushion blocks (3); a jackscrew threaded rod (1) is in internal threaded connection with the internal bearing cover (4); and the lower end of the jackscrew threaded rod (1) is pressed against a balance ring (5). The device has the characteristics of reducing the perfectness ratios of the bearing and bearing position accuracy after the bearing is disassembled, shortening the disassembly time of the bearing, reducing the cost and the like.
Description
Technical field
The utility model relates to machine field, especially a kind of motor bearings provision for disengagement.
Background technology
The existing above motor of 7.5kw all is to adopt traditional grease lubrication and protect oily mode with internal bearing cover and bearing end cover.When motor carries out maintenance and repair, all adopt traditional holder of drawing that bearing is forced dismounting.Its method is: put a centre bore protective sleeve at the rotating shaft spindle nose, with drawing the threaded mandrel of holder that the protective sleeve centre bore is withstood, 3 pawls that draw holder are colluded catch outer race, firmly the threaded mandrel of holder is drawn in rotation again, by force bearing is pulled down from rotating shaft.Because outer race is stressed too quickly, there is the bearing more than 95% all therefore to damage during dismounting; When particularly periodicmaintenance is changed bearing; Have split bearing when dismounting, can because of various reasons the outer shroud and the retainer of bearing be left behind, bearing inner ring is stayed on the axle and can't be disassembled, and can only adopt abrasive wheel cutting machine to cut or go up lathe its processing is machined away; Every motor through above method dismounting; Not only bearing is scrapped, and its shaft bearing position precision also can receive certain damage, the hidden danger that causes rotating shaft to scrap in addition.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, motor bearings provision for disengagement that can be for convenience detach.
The technical scheme that purpose adopts of the utility model is, comprises bearing, internal bearing cover, gimbal, and its internal bearing cover has 3-8 internal thread holes; Be placed with two arc cushion blocks between bearing inner ring and the internal bearing cover, the arc cushion block has the iron wire colligation outward; The jackscrew screw rod is connected with the internal bearing cover internal thread, and withstand with gimbal mutually jackscrew screw rod lower end.
Use the utility model; Two arc cushion blocks are positioned over bearing root place, withstand the interior ring of bearing, its colligation is fixed from the cushion block groove with the thing of copper wire or iron wire and rope and so on again; Use 3-4 jackscrew screw rods to be screwed into respectively again from the screw of internal bearing cover; Withstand the rotor balancing ring up to the jackscrew screw rod, continue again the jackscrew screw rod is screwed into inwards, can bearing removal be come out.Therefore this method, can guarantee that the retainer of bearing and steel ball dismounting back are without any damage because bearing inner ring is stressed evenly.
The utility model, serviceability rate, shortening bearing removal time with the bearing that improves behind the dismounting bearing and bearing position precision, characteristics such as reduce the cost.
