Abstract

The utility model discloses a bearing demounting device and aims to solve the problems of high manufacturing cost and failure in recycling of a demounted bearing due to damage of the demounted bearing in the prior art. The bearing demounting device comprises an ejector rod and a base with a fixing gap, a support parallel to the base is arranged above the base and provided with a round hole pointing to the fixing gap of the base, and the ejector rod longitudinally penetrates through the round hole and points to the fixing gap. The bearing is fixed by the fixing gap, the ejector rod is abutted against an inner ring shaft of the demounted bearing, and the bearing is demounted by enabling the ejector rod to move downwards on the premise of damage prevention. The bearing demounting device is simple in operation and high in practicality, and the bearing can be manually demounted in good condition.

Description

A kind of bearing disassembling device

Technical field

The utility model relates to machine components provision for disengagement, is specifically related to a kind of bearing disassembling device.

Background technology

Bearing is being played the part of important role in the swinging axle of supporting machinery system and rotating shaft, but because general bearing bore diameter and axle are all interference fit, in its unloading process, still have because some technical problems cause the damage of bearing demolition or the wearing and tearing of rod member.In order to improve this problem, bearing disassembling device and the fluid bearing provision for disengagement etc. of La Mashi are there is in the market.The former is manual bearing disassembling device, manually bearing demolition is placed into assigned address, by pull bar, bearing is fixed, pulled out by screw rod again, but because frictional force is greatly easily pulled axle, can not be dismantled the problems such as the long bearing arrangement of axle and pull bar and bearing inner race contact position easily skid and make removal efficiency not high; The latter utilizes to be arranged on hydraulic system in device automatically by bearing removal, but very easily to bearing demolition cause damage cause bearing not reuse and manufacturing cost higher.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of bearing disassembling device is provided, and this device adopts the rectilinear method ejecting, and makes bearing removal efficiency higher, reduces because technical problem causes that bearing demolition can not reuse, the damage of axle etc.

In order to achieve the above object, the utility model comprises push rod and has the base of fixed interval (FI), above base, is provided with the support parallel with base, offers the circular hole that points to base fixed interval (FI) on support, and push rod longitudinally runs through circular hole and points to fixed interval (FI).

On described base, be provided with two clamps, the both sides of two clamps laterally connect by bolt, extend on the bolt of clamp and are provided with nut.

Described push rod has external screw thread, and the circular hole on support has the internal thread matching with the external screw thread of push rod.

The top of described push rod is provided with horizontal handle.

Compared with prior art, the utility model is by fixed interval (FI) rigid bearing, push rod withstands on the inner ring axle of bearing demolition, by push rod is moved downward, ensure under not impaired prerequisite under bearing removal, the utility model has been realized the manual bearing removal of high efficiency, low damage, and simple to operate, practical.

Further, the utility model can regulate the distance that clamps interblock according to the size of bearing demolition, with nut, clamp is accurately located again, ensure the positional precision of bearing demolition, effectively avoid bearing in unloading process because the reason such as skid, clamp excessively causes the damage of bearing self and can not reuse.

Further, the utility model is provided with handle on push rod top, carrys out the motion of drive screw by handle, easy to operate simple.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is base support schematic diagram of the present utility model;

Fig. 3 is fundamental diagram of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to Fig. 1 and Fig. 2, a kind of bearing disassembling device of the utility model, comprise the base 1 that there is externally threaded push rod 7 and there is fixed interval (FI), on base 1, be provided with two clamps 2, the both sides of two clamps 2 laterally connect by bolt 3, extend on the bolt 3 of clamp 2 and be provided with nut 4, can regulate according to the size of bearing demolition the spacing of 2 of clamps, two clamps are bearing on the bearing inner race of bearing demolition just, locate by nut 4 again, ensure the positional precision of unloading process middle (center) bearing, base 1 top is provided with the support parallel with base 15, on support 5, offer the circular hole of the internal thread matching with the external screw thread of push rod 7, circular hole points to the fixed interval (FI) of base 1, push rod 7 longitudinally runs through circular hole and points to fixed interval (FI), the top of push rod 7 is provided with horizontal handle 6.

Referring to Fig. 3, operation principle of the present utility model is as follows, the clamp 2 arranging on base 1 carrys out spacing according to the size of bearing demolition, support respectively the bearing inner race of bearing demolition, by nut 4, bearing is accurately located again, after bearing demolition is well placed, make push rod 7 downward vertically in ground setting in motion by turning handle 6, screw rod withstands on the inner ring axle of installation and bearing demolition just, under the self gravitation of axle, be rotated further handle, thus ensure bearing demolition under not impaired prerequisite by under bearing removal.

The feature of this device is to have realized the manual bearing removal of high efficiency, low damage, does not need the action that adopts traditional pressure, strike, draw or the equipment of more complicated to dismantle.

This apparatus can meet the operation requirements of operator for bearing removal high efficiency, low damage, all can use in indoor and outdoor, and the scope of application is wider.Due to the technology adopting be also easily understood, relatively ripe, production cost is also lower.
