Description

Novel bearing puller

Technical Field

The utility model belongs to the technical field of tobacco equipment repair tools, concretely relates to novel bearing puller.

Background

In the traditional bearing drawing process, a puller is hooked on an inner ring of a bearing, and then drawing operation is carried out. However, in the practical use process, the hooked position of the puller is easy to slip to the rolling body, the retainer or the outer ring of the bearing, and the puller directly acts on the rolling part, the retainer or the outer ring when the pulling operation is carried out, so that the bearing is damaged, and the disassembled bearing must be scrapped.

Therefore, there is a need to design a puller which can not only realize the quick disassembly of the bearing, but also effectively avoid the damage to the bearing.

Disclosure of Invention

The utility model discloses a novel bearing puller can realize the quick dismantlement of bearing, and the face of drawing moreover is the face contact with the bearing, can effectively avoid causing the damage to the bearing, and this puller external member simple structure has wider application scope simultaneously.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the utility model provides a novel bearing puller, includes the ladle body, goes up the ladle plate, lower ladle plate and ejector pin, and the ladle body top is fixed with the upper barrel plate, goes up the ladle plate center and sets up threaded hole, and the recess that is used for placing the bearing is offered to the ladle body lower part, and the lower ladle plate that is used for supporting the bearing is installed to the bottom, sets up the shaft groove that supplies the axle to pass on the lower ladle plate, the pole of ejector pin is equipped with the screw thread on the body, ejector pin and last ladle plate threaded connection, and the ejector pin lower extreme stretches into in the recess of ladle body lower.

Furthermore, the lower end of the ejector rod is of a conical structure.

Furthermore, the upper end of the ejector rod is of an outer hexagonal structure.

The utility model discloses beneficial effect:

the utility model discloses a lower barrel plate supports the bearing, barrel plate shaft groove under the transmission shaft embedding, bearing and lower barrel face contact, and the pulling force can not be used in single spare parts such as roll portion, holder or outer lane completely, but is shared equally by whole bearing end face, can effectively avoid causing the damage to the bearing. Meanwhile, the puller external member is simple in structure, convenient to manufacture and wide in application range.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the embodiments of the present invention and the accompanying drawings, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1-4, a novel bearing puller comprises a barrel body 1, an upper barrel plate 2, a lower barrel plate 3 and a mandril 4, wherein the upper barrel plate 2 is fixed at the top of the barrel body 1, a threaded hole is arranged in the center of the upper barrel plate 2, a groove 5 for placing a bearing is arranged at the lower part of the barrel body 1, the lower barrel plate 3 for supporting the bearing is arranged at the bottom, a shaft groove 6 for a shaft to pass through is arranged on the lower barrel plate 3, the upper barrel plate 2 and the lower barrel plate 3 are both thickened plates, the bearing capacity in the use process is ensured, when the bearing puller is detached, the bearing is arranged in the groove 5 at the lower part of the barrel body 1, a transmission shaft is clamped into the shaft groove 6 of the lower barrel plate 3, the lower barrel plate 3 is used as a bottom supporting piece of the groove 5, the width of the shaft groove 6 is matched with the diameter of the transmission shaft, the bearing is in surface contact with the lower barrel plate 3 during the detaching process, but the whole bearing end surface is shared, so that the damage to the bearing can be effectively avoided. The pole of ejector pin 4 is equipped with the screw thread on one's body, 2 threaded connection on ejector pin 4 and the last barrel head, and 4 lower extremes of ejector pin stretch into in the recess 5 of 1 lower part of ladle body, and 4 lower extremes of ejector pin are the toper structure, and the apical pore that toper structure and axle add man-hour cooperatees, guarantees to dismantle the in-process at the bearing, and 4 lower extremes of ejector pin can push up all the time and put at the transmission shaft central point, and the upper end is outer hexagonal structure, is convenient for rotate ejector pin 4 with the help of hexagonal spanner etc. and operates more laborsavingly convenient. When the bearing is disassembled, the bearing is placed in the groove 5 of the barrel body 1, the bearing is in surface contact with the lower barrel plate 3 of the barrel body 1, the transmission shaft is clamped into the shaft groove 6 of the lower barrel plate 3, the ejector rod 4 is in threaded connection with the central threaded hole of the upper barrel plate 2, the ejector rod 4 is rotated by a wrench to abut against the axis of the transmission shaft, and the bearing is pulled off from the transmission shaft. The utility model discloses a 3 pairs of bearings of lower barrel boards support, 3 shaft grooves 6 of barrel boards under the transmission shaft embedding, bearing and 3 face contact of lower barrel board, the pulling force can not be used in single spare parts such as roll portion, holder or outer lane completely, but by whole bearing end face all stand in a stall, can effectively avoid causing the damage to the bearing. Meanwhile, the puller external member is simple in structure, convenient to manufacture and wide in application range.

The present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
