Abstract

A special-purpose tool for disassembling ball bearing belongs to the technical field of hand tools, which is used to solve the problem of difficult disassembly of a bearing. The utility model adopts the technical scheme that the special-purpose tool comprises a screw rod, a nut mold, a bearing pull-out part and a handle, wherein the screw rod is arranged on the center of the nut mold, and is screwed with the nut mold, the handle is penetrated through one end of the screw rod, slotted holes are evenly distributed on the nut mold, the middle portion of the bearing pull-out part is located in each slotted hole, a nut is arranged on one end of the bearing pull-out part, and a plate pull-out head is arranged on the other end thereof. The special-purpose tool can pull out a bearing through utilizing the screw transmission action of the screw rod without disassembling a heavy case cover and related parts, which not only can lighten the work intensity and increase the work efficiency, but also can avoid the weakness of damaging parts caused by smashing and colliding in the process of disassembling the bearing. The special-purpose tool has simple structure, smart design and easy realization.

Description

A kind of specific purpose tool that is used to dismantle ball bearing

Technical field

The utility model relates to a kind of assembly tool, especially for the specific purpose tool of the middle-size and small-size radial ball bearing of dismounting, belongs to the hand-operated tools technical field.

Background technology

All adopt the bearing shell transmission between each and axle bed in the Weaving device in past, the especially loom, the kind of drive power consumption height of this sliding bearing, frictional force are big, are not suitable for the high speed transmission.At present, the most of transmission of loom has all substituted sliding bearing with rolling bearing, has not only improved transmission efficiency, has reduced energy consumption, has also realized the high speed transmission.But based on loom structure, rolling bearing is in wearing and tearing or damage when needing to change, unload next bearing from casing wastes time and energy very much, not only will dismantle down heavy case lid and many associated components, also need to pound, dash with instrument, this mode is easy to casing or axle are caused damage.Therefore, design a kind of can be fast, the instrument of easy removal rolling bearing, very necessary for the loom maintenance personal.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of specific purpose tool that is used to dismantle ball bearing is provided, and utilizes this specific purpose tool to need not to dismantle the bearing that case lid can fast unload damage.

The alleged problem of the utility model solves with following technical proposals:

A kind of specific purpose tool that is used to dismantle ball bearing, its special feature is: it is made of leading screw, screw mould, a bearing part and handle, described leading screw is positioned at screw mould center, is connected with its spiral, handle passes leading screw one end, uniform slotted eye on the screw mould, play the bearing part middle part and be positioned at each slotted eye, play bearing part one end and be provided with nut, the other end is provided with tabular starting.

The above-mentioned specific purpose tool that is used to dismantle ball bearing: described tabular starting to discoideus or triangle is tabular.

The above-mentioned specific purpose tool that is used to dismantle ball bearing: described screw mould is the class triangle, and described slotted eye is three.

The utility model has designed a kind of specific purpose tool that is suitable for dismantling middle-size and small-size radial ball bearing at the problem of loom bearing dismounting and change difficulty, this instrument is made up of leading screw, screw mould, a bearing part and handle, during removing damaged bearing, probe in the bearing enclose of damage playing bearing part, tangle bearing, utilize the spiral power transmission principle of leading screw, bearing is extracted.Adopt the utility model dismounting bearing to need not to dismantle heavy case lid and correlated parts, not only can alleviate the maintenance personal working strength, increase work efficiency, can also avoid in dismounting bearing process drawback because of operation damage parts such as pounding, dash.The utility model is simple in structure, be skillfully constructed, be easy to realize.

The specific embodiment

Referring to Fig. 1, Fig. 2, the utility model is made of leading screw 2, screw mould 3, a bearing part 4 and handle 1, described leading screw is arranged in the screwed hole at screw mould center, be connected with the screw mould spiral, handle passes leading screw one end, and the screw mould is the class triangle, uniform three slotted eye 3-1 on it, each rises, and bearing part passes slotted eye, wherein portion is arranged in each slotted eye, plays bearing part one end and is provided with nut 4-1, and the other end is provided with the tabular 4-2 of starting.

Referring to Fig. 2～6, be to adapt to the ball bearing dismounting of different size, play a bearing part and designed start size or variform one group of selective use, tabular as seen from the figure starting to discoideus or triangle is tabular.

When the utility model is used for removing damaged radial ball bearing, select the suitable bearing part that rises to be installed on the screw mould, three bearing parts are inserted between the Internal and external cycle of bearing, the leading screw end withstands on the parts place, rotate three respectively and play bearing parts 90 degree, making starts tangles the Internal and external cycle of bearing, locking nut, turning handle utilizes the reaction force of leading screw the bearing that damages can be extracted.
