Abstract
The invention discloses a needle roller bearing with damping, and aims to provide a needle roller bearing with damping, which is simple in structure, is convenient to manufacture and has a long service life. The needle roller bearing comprises an outer roller path, wherein retaining sides are arranged at the two ends of a hole of the outer roller path; and needle rollers distributed in the circumferential direction are mounted in the outer roller path and are separated by cages. The needle roller bearing is characterized in that a ring-shaped sleeve is mounted between an inner hole wall of the outer roller path and the needle rollers, wherein one end of the ring-shaped sleeve is in a round shape, and the other end of the ring-shaped sleeve is in an irregular round shape with an edge and smoothly transits towards the round-shaped end. When the needle rollers of the needle roller bearing roll in the irregular-round-shaped end of the ring-shaped sleeve, the ring-shaped sleeve is elastically deformed, so the needle roller bearing has certain damping during the rolling; and the size of the damping can be determined according to the irregular degree of the ring-shaped sleeve and the thickness of a material. The needle roller bearing has the advantages of simple structure and convenience in manufacturing and mounting, can be used as moving rolling bearings for doors, windows, and the like, and can be used in equipment such as instruments and meters having special requirements.
Description
Technical field
The present invention relates to bearing, particularly a kind of needle bearing with band damping.
Background technique
Most needle bearing all requires to roll flexibly; When rolling, there is not catching phenomenon; But the instrument, instrument of specific (special) requirements arranged because the inertial force of motion can influence the precision or the location of test for some, therefore, hope that bearing do not giving under the situation of power and can not stop operating at once; Require some dampings that itself have of bearing, but common needle bearing all there is not this function.
Summary of the invention
The needle bearing that the purpose of this invention is to provide a kind of band damping of simple in structure, easily manufactured, long service life.
In order to reach above-mentioned requirements; The present invention realizes through following technological scheme: there is the outer raceway of rib at the two ends that it comprises the hole, and the needle roller of circumferential distribution is installed in the raceway outside, have retainer to separate between each needle roller; It is characterized in that between inner hole wall and the needle roller of raceway outside the annular cover being installed; Described annular cover one end is circular, and the other end is the non-regular circle of band rib, and to the smooth-going transition of round nose.
Described outer raceway is processed with plastics or rubber material.
Be shaped on inside flange at described annular cover round nose.
Described flange is the 3-4 place that is uniformly distributed with.
The wall thickness of said annular cover is the 0.2-0.5 millimeter.
The plain washer of annular is installed in the non-regular circular end surface of described annular cover.
Needle bearing according to the band damping of such scheme design; Needle roller is not in the positive circumferential surface of rule, to roll; But at non-regular circle and have rolling in certain flexible annular cover; When needle roller rolled in non-regular circle, resiliently deformable took place in the annular cover, made this needle bearing when rolling, have certain damping.The big I of damping is confirmed according to the degree of annular cover irregularity and the thickness of material.It has simple in structure, makes convenient installation, can be used as mobile rolling bearing such as door, window, and has in the equipment such as instrument, instrument of specific (special) requirements and use.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further description.
Fig. 1 is the structural representation of the needle bearing of band damping.Find out that from figure there is the outer raceway 2 of rib 1 at the two ends that it comprises the hole, outer raceway 2 usefulness plastics or rubber material are processed.The needle roller 3 of circumferential distribution is installed in the raceway 2 outside; 3 of each needle rollers have retainer 4 to separate; Annular cover 5 is installed outside like Fig. 2, Fig. 3, shown in Figure 4 between the inner hole wall of raceway 2 and the needle roller 3; Described annular cover 5 one ends be circular 6, and the other end is non-regular circular 7 for the band rib, and hold suitable transition level with both hands to circular 6.The wall thickness of annular cover 5 is the 0.2-0.5 millimeter.Overlap 5 circular 6 ends in annular and be shaped on the inside flange 8 in 3-4 place that is uniformly distributed with.Overlap the plain washer 9 that 5 non-regular circular 7 end faces are equipped with annular in annular.
Claims (6)
1. be with the needle bearing of damping; There is the outer raceway of rib at the two ends that it comprises the hole, and the needle roller of circumferential distribution is installed in the raceway outside, have retainer to separate between each needle roller; It is characterized in that between inner hole wall and the needle roller of raceway outside the annular cover being installed; Described annular cover one end is circular, and the other end is the non-regular circle of band rib, and to the smooth-going transition of round nose.
2. the needle bearing of band damping according to claim 1 is characterized in that described outer raceway processes with plastics or rubber material.
3. the needle bearing of band damping according to claim 1 is characterized in that being shaped on inside flange at described annular cover round nose.
4. the needle bearing of band damping according to claim 3 is characterized in that described flange is the 3-4 place that is uniformly distributed with.
5. the needle bearing of band damping according to claim 1 is characterized in that the wall thickness of said annular cover is the 0.2-0.5 millimeter.
