Full needle punching needle bearing with retainer

Technical Field

The utility model relates to a bearing technical field especially relates to a full needle punching press bearing with holder.

Background

The drawn cup needle bearing is a needle bearing with a thin press-formed cup, and is mainly characterized in that the section height is very low, the load bearing capacity is high, and the drawn cup needle bearing is mainly used for bearing configuration with compact structure, low price and bearing box inner hole incapable of being used as a needle roller retainer assembly raceway.

However, the full needle bearing is generally high in load, the internal space of the full needle bearing is limited, and no retainer structure is arranged in the structure mode.

However, the needle drop of the needle roller bearing is limited before assembly by adopting a structure of locking the needle or grease, so that the service life and the rotating speed of the bearing are influenced to a certain extent, certain risks exist, and the use of the bearing is limited.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a full needle punching press bearing with holder, the needle condition that falls before the assembly is limited to structure lock needle or grease basically adopted to the kingpin of having solved bearing among the prior art appears, and such mode all has certain influence to the life-span and the rotational speed of bearing, has certain risk, and has restricted the problem of the use of bearing.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the full needle punching needle bearing with the retainer comprises an outer shaft sleeve, wherein an inner ring of the outer shaft sleeve is rotatably connected with an inner shaft sleeve through a plurality of needle rollers circumferentially arrayed in the circumferential direction, and the retainer is arranged on two sides of the top of each needle roller.

Preferably, the bottom of each retainer and the top of the outer shaft sleeve are provided with connecting grooves matched with the retainer.

Preferably, both sides of the top of each retainer are in threaded connection with a screw rod penetrating through the retainer, and both sides of the bottom of each connecting groove are provided with screw holes matched with the screw rods.

Preferably, the center of the top of each screw hole is provided with a hexagonal groove.

The utility model discloses possess following beneficial effect at least:

before the bearing is transported and assembled, the retainer is firstly inserted into the connecting groove in an inserting mode, then the retainer is fixedly connected with the connecting groove bolt through connection of the screw rod and the screw hole, the retainer effectively blocks the roller pin, the roller pin cannot fall off from the outer sleeve, the axial force of the roller pin cannot be influenced due to the fact that the roller pin cannot be directly contacted with the needle point of the roller pin, the service life of the prolonged bearing is prolonged, the rotating speed of the bearing is protected, the retainer is convenient to disassemble and assemble, and operation is convenient.

The utility model discloses still possess following beneficial effect:

through the setting of holder, effectually block the kingpin, make it can't drop from outer axle sleeve, because can not direct and the needle point contact of kingpin, can not influence the axial force of kingpin, the life of the bearing of extension has protected the rotational speed of bearing, has guaranteed the normal use of bearing.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without any creative effort.

fig. 3 is a schematic structural diagram of fig. 2A according to the present invention.

In the figure: 1. an outer sleeve; 2. a holder; 3. an inner sleeve; 4. connecting grooves; 5. rolling needles; 6. a screw hole; 7. a hexagonal groove; 8. a screw.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a full needle punching needle bearing with a retainer comprises an outer shaft sleeve 1, wherein an inner ring of the outer shaft sleeve 1 is rotatably connected with an inner shaft sleeve 3 through a plurality of rolling needles 5 circumferentially arrayed in the circumferential direction, the retainer 2 is arranged on two sides of the top of each rolling needle 5, specifically, the rolling needles are effectively blocked by the retainer 2, so that the rolling needles cannot fall off from the inner part of the outer shaft sleeve 1, the axial force of the rolling needles cannot be influenced due to the fact that the rolling needles cannot be directly contacted with the needle points of the rolling needles, the service life of the bearing is prolonged, the rotating speed of the bearing is protected, and the normal use of the bearing is ensured.

The scheme has the following working processes:

before the bearing is transported and assembled, firstly, the retainer 2 is inserted into the connecting groove 4 in an inserting mode, then the retainer 2 is fixedly connected with the connecting groove 4 through the screw rod 8 and the screw hole 6, the retainer 2 effectively blocks the roller pin 5, the roller pin cannot fall off from the outer shaft sleeve 1, the axial force of the roller pin 5 cannot be influenced due to the fact that the retainer cannot be directly contacted with the needle point of the roller pin 5, the service life of the prolonged bearing is prolonged, the rotating speed of the bearing is protected, the retainer 2 is convenient to disassemble and assemble, and operation is convenient.

According to the working process, the following steps are known:

through the setting of holder 2, effectually block kingpin 5, make it can't fall from outer axle sleeve 1 in, owing to can not direct and kingpin 5's needle point contact, can not influence kingpin 5's axial force, the life of the bearing of extension has protected the rotational speed of bearing, has guaranteed the normal use of bearing.

Further, the bottom of every holder 2 and the top position that is located outer axle sleeve 1 all offer with the spread groove 4 of holder 2 looks adaptation, it is concrete, through the setting of spread groove 4, be convenient for connect holder 2, and can not occupy outer lane space of outer axle sleeve 1.
