Description

Special bearing extracting tool

Technical Field

The utility model relates to a special bearing extracting tool.

Background

The puller is needed to be used for disassembling the friction roller bearing of the winding head, the puller with two claws is adopted in the prior art, and the technology has two defects: firstly, the operation is very inconvenient, and due to the structural particularity of the friction roller, the operation space of the puller is limited, a part of the hook of the two-claw puller needs to be ground in advance to be placed in the puller, and the hook is not easy to hook; secondly, the working efficiency is low.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a special bearing extracting tool has effectively solved the problem of pointing out among the background art.

The utility model adopts the technical proposal that:

the utility model provides a special bearing extracting tool, includes the semicylinder that two symmetries set up, the front end of semicylinder inwards is equipped with the couple, the perpendicular inward fixation of rear end of semicylinder has the spacing step of backup pad, two the semicylinder is equipped with the backup pad in the inboard of the spacing step of backup pad, the screw has been seted up at the center of backup pad, the screw in the matching be equipped with the ejector pin, the outside of ejector pin seted up with screw assorted screw, two the outside of semicylinder is equipped with the position sleeve.

Preferably, the supporting plate limiting step is circular.

The annular supporting plate limiting step is matched with the supporting plate, so that the stress is more stable and reliable, and the service life is prolonged.

Preferably, the positioning sleeve is in clearance fit with the two semi-cylinders.

Preferably, the rear end of the ejector rod is provided with a rotary operating head.

Preferably, the rotary operating head is a nut integrally formed with the carrier rod.

The nut-shaped rotary operating head can be directly operated by a wrench, and is simple in structure and convenient to use.

The utility model discloses according to the structural feature of coiling head friction roller bearing, adopt the structure of position sleeve and two semicylinders, can make the couple easily put into, solved the limited problem in horse-drawing operation space, simultaneously, the utility model discloses catch on more easily, improved dismantlement efficiency.

fig. 2 is a schematic view of the use structure of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.

Example 1

As shown in fig. 1-2, a special bearing extracting tool comprises two semicylinder bodies 1 which are symmetrically arranged, a hook 2 is inwards arranged at the front end of each semicylinder body 1, a supporting plate limiting step 3 is vertically and inwards fixed at the rear end of each semicylinder body 1, a supporting plate 4 is arranged on the inner side of each semicylinder body 1 at the supporting plate limiting step 3, a screw hole 5 is formed in the center of each supporting plate 4, an ejector rod 6 is arranged in each screw hole 5 in a matched mode, threads matched with the screw hole 5 are formed in the outer side of each ejector rod 6, and a positioning sleeve 7 is arranged on the outer side of each semicylinder body 1.

The supporting plate limiting step 3 is in a ring shape.

The locating sleeve 7 is in clearance fit with the two semi-cylindrical bodies 1.

The rear end of the ejector rod 6 is provided with a rotary operating head 8.

The rotary operating head 8 is a screw cap which is integrally formed with the ejector rod 6.

The utility model discloses a theory of operation:

firstly, hooks 2 of two semicylinder bodies 1 are respectively hooked with oil slingers 11, then a support plate 4 and a mandril 6 are arranged in the two semicylinder bodies 1, then positioning sleeves 7 are sleeved on the outer sides of the two semicylinder bodies 1, the mandril 6 is rotated by a rotating operating head 8, the mandril 6 is ejected forwards, the support plate 4 props against a support plate limiting step 3, at the moment, the semicylinder bodies 1 pull the oil slingers 11 and bearings 12 backwards until the bearings 12 are dismantled, and the device is very convenient and reliable to operate; the working efficiency is high.

Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
