Abstract

The utility model discloses a bearing detaching pull hammer device, which is provided with an 'n'-shaped stretching seat. Two bolt holes are respectively arranged on horizontal bending portions on two sides of the stretching seat, one end of a bolt located in each bolt hole is welded on a bearing to be detached, the other ends, which are located on the outer sides of the horizontal bending portions of the stretching seat, of the bolts are respectively connected with a rod via inner threads, the two rods are respectively sleeved with a steel sleeve in a slide fit manner, and steel sleeve retaining shoulders are arranged at outer side ends of the rods. The bearing detaching pull hammer device is simple in structure, can conveniently detach the bearing required to be replaced, saves time and labor, and is convenient in use.

Description

Bearing removal draws the hammer device

Technical field

The utility model relates to a kind of bearing disassembling device that is used for big-and-middle-sized plant equipment, and particularly a kind of bearing removal draws the hammer device.

Background technology

At present, when the bearing of installing on a lot of machines need be changed, because the time that bearing is installed is long, cooperates tightlyer, dismounting and change is pretty troublesome, mainly is because of often being not easy to the application of force when dismantling bearing, having no way of doing it sometimes.Particularly when bearing was changed in large and medium-sized overhaul of the equipments, because there is not suitable specific purpose tool, maintenance replacing bearing was required great effort time-consuming especially, influences production efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of bearing removal to draw the hammer device, and it is simple in structure, can dismantle the bearing that needs replacing easily, and is time saving and energy saving, easy to use.

The purpose of this utility model is to realize like this, a kind of bearing removal draws the hammer device, this provision for disengagement has more than one font tractive seats, on the horizontal bending part in the both sides of tractive seat a bolt hole is being set respectively, bolt one end that is positioned at bolt hole is welded on the bearing to be removed, the bolt other end that is positioned at the horizontal bending part of the tractive seat outside is connecting a body of rod respectively by internal thread, is the suit that is slidingly matched on two bodies of rod respectively and a joint steel bushing, and the outboard end of the body of rod has the steel bushing shoulder block.

When the utility model uses, promote the outside high-speed motion of steel bushing respectively by a people or two people and impact the steel bushing shoulder block, by bolt bearing is applied outside pulling force, thereby can dismantle the bearing that needs replacing easily, time saving and energy saving, easy to use.Can also between bearing and tractive seat, place a jack,, the axle and the bearing inner sleeve of bearing be extracted by the operation jack.The utility model is simple in structure, is easy to make, be particularly suitable for when changing the used bearing of big-and-middle-sized equipment, using, and be the simple and easy extracting tool of a kind of more satisfactory bearing.

Description of drawings

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

Fig. 1 is a main TV structure schematic diagram of the present utility model.

The specific embodiment

A kind of bearing removal draws the hammer device, as shown in Figure 1, this provision for disengagement has more than one font tractive seats 6, on the horizontal bending part in the both sides of tractive seat 6 bolt hole is being set respectively, bolt 2 one ends that are positioned at bolt hole are welded on the bearing to be removed 1, bolt 2 other ends that are positioned at the horizontal bending parts of tractive seat 6 outside are connecting respectively by internal thread and are being the suit that is slidingly matched on a body of rod 3, two bodies of rod 3 respectively and a joint steel bushing 4, and the outboard end of the body of rod 3 has steel bushing shoulder block 5.

During use, promote steel bushing 4 outside high-speed motions respectively by a people or two people and impact steel bushing shoulder block 5, apply outside pulling force by 2 pairs of bearings 1 of bolt, thereby can dismantle the bearing that needs replacing easily, time saving and energy saving, easy to use.Can also between bearing 1 and tractive seat 6, place a jack 7,, the axle and the bearing inner sleeve of bearing 1 be extracted by operation jack 7.The utility model is simple in structure, can dismantle the bearing that needs replacing easily, and is time saving and energy saving, easy to use.

Claims

1. a bearing removal draws the hammer device, it is characterized in that: this provision for disengagement has more than one font tractive seats, on the horizontal bending part in the both sides of tractive seat a bolt hole is being set respectively, bolt one end that is positioned at bolt hole is welded on the bearing to be removed, the bolt other end that is positioned at the horizontal bending part of the tractive seat outside is connecting a body of rod respectively by internal thread, be the suit that is slidingly matched on two bodies of rod respectively and a joint steel bushing, the outboard end of the body of rod has the steel bushing shoulder block.
