Description

Full needle punching press needle bearing with adjustable retainer

Technical field

The utility model relates to technical field of bearings, the full needle punching press needle bearing of especially a kind of adjustable retainer of band.

Background technique

Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee its rotating accuracy, and needle bearing is the roller bearing with cylindrical roller, relatively Its diameter, roller is not only thin but also long, and this roller is known as needle roller, and full needle bearing adds full needle bearing by interior because its load is big Portion space limitation, structure type is the structure without retainer so that bearing in rotation by biggish axial force, it is right The service life of bearing and revolving speed all have a great impact, and are badly in need of a kind of full needle punching press needle bearing with retainer, such as Patent No. CN201420122635.4, the applying date are on March 19th, 2014, and patent name is " the full needle punching press needle roller axis with retainer Hold ", which improves bearing load carrying capacity by the way that retainer with internal lock pin hole is arranged in needle roller inner wall, but the structure Using plastic material, bearing capacity is simultaneously bad, and soundproof effect is also poor, and structure fixation is non-adjustable, can not meet people and increasingly increases Long use demand.

Utility model content

In order to overcome the fixed nonadjustable deficiency of existing structure, the utility model provides a kind of adjustable retainer of band Full needle punching press needle bearing, is solved the problems, such as by the stretchable retainer with sound-proof material.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of full needle punching press of the adjustable retainer of band Needle bearing, including outer ring, needle roller and retainer, needle roller are uniformly arranged between outer ring and retainer, and retainer is connected by middle part It connects the stop collar of ring and both ends with rib to constitute, connection ring and stop collar are fixedly connected by tensioning member, connection ring and limit Washer is provided on the contact surface of position ring and needle roller, retainer realizes stretchable adjusting, and washer can not only limit needle roller Position clamping, moreover it is possible to realize damping and silencing.

It further, is the button bar for being fixed at connection ring both ends including tensioning member, button bar is opened up with stop collar end Through-hole be adapted, simple stretching structure is easy to use.

Further, including offering the cavity stretched for button bar in stop collar, convenient for the progress of stretching.

Further, it is provided with including button bar end for limiting fixed triangle card, is convenient for button bar clamping.

Further, including washer is made of silencing cotton cushion block, and silencing cotton damping and silencing effect is good.

The utility model has the beneficial effects that replacing traditional fixed structure by split type stretching structure, flexibility is good, The needle bearing of different length is applicable in, while the washer of silencing cotton material carries out clamping fixed to needle roller, moreover it is possible to be bearing Play the role of damping and silencing, effectively improves bearing service efficiency.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the cross-sectional view of the utility model；

Fig. 2 is the retainer sectional view of the utility model；

Fig. 3 is the tensioning member schematic diagram of the utility model.

1. outer ring in figure, 2. needle rollers, 3. retainers, 31. connection rings, 32. stop collars, 4. washers, 5. button bars, 6. triangle cards Block, 7. cavitys, 8. cushion blocks.

Specific embodiment

As shown in Figure 1, 2, the full needle punching press needle bearing of the adjustable retainer of a kind of band, including outer ring 1, needle roller 2 and holding Frame 3, needle roller 2 are uniformly arranged between outer ring 1 and retainer 3, limit of the retainer 3 by middle part connection ring 31 and both ends with rib Ring 32 is constituted, and connection ring 31 and stop collar 32 be fixedly connected by tensioning member, connection ring 31 and stop collar 32 and needle roller 2 Washer 4 is provided on contact surface, washer 4 is made of silencing cotton cushion block 8.When installing and using, according to 2 length of needle roller by retainer 3 are stretched, so that stop collar 32 of the both ends with baffle is fastened on 2 both ends of needle roller, while preventing needle roller 2 from deviating from, are enhanced Washer 4 on the bearing capacity of bearing, retainer 3 and 2 contact surface of needle roller uses silencing cotton material, while fixed needle roller 2, Also it can play the role of good vibration-absorbing and silencing in bearing use process.

As shown in figure 3, tensioning member is the button bar 5 for being fixed at 31 both ends of connection ring, button bar 5 is opened with 32 end of stop collar If through-hole be adapted, the cavity 7 stretched for button bar 5 is offered in stop collar 32,5 end of button bar is provided with solid for limiting Fixed triangle card 6.The adjustable of retainer 3 is realized by simple tensioning member, improves flexibility, when needing to adjust, is only needed Button bar 5 is stretched, screw is pressed by the corresponding position in cavity 7 after regulating, button bar 5 is fixed, screw rod Retainer 3 cannot be stretched out, with the normal use of obstruction free bearing, connection ring 31 upper and lower ends in middle part are circle with 31 center of connection ring The heart is evenly arranged at least six groups of tensioning members, is stably connected with realizing.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait Effect, but all will fall within the protection scope of the utility model.
