Description
The invention belongs to a kind of mechanical bearings, specifically, is a kind of centripetal thrust force two-layer compound needle bearing that is suitable for all kinds of load-carrying vehicles and machinery.
Angular contact ball bearing is arranged in the prior art, and tapered roller bearing, combination needle bearing etc. still do not have double-deck compound needle bearing.The bearing capacity of existing combination needle bearing is big, and it is more steady to turn round.In being suitable for, low cruise, but in all kinds of load-carrying vehicles and machinery the heavy duty, when running up, the usability variation, shorten working life greatly, wearing and tearing power consumption sharply increase.
The object of the present invention is to provide a kind of bearing capacity big, running is steady, long service life, and the wearing and tearing power consumption is significantly less than the new-type rolling bearing of existing all kinds of rolling bearings.
For achieving the above object, the present invention has done following improvement to existing combination needle bearing: change the needle roller of former single belt retainer the needle roller body of bilayer zone retainer into, and install a bearing middle cover additional to separate between two-layer needle roller body; Former roller step bearing body and retainer thereof are retrofitted between the interior edge face of end face of bearing middle cover and bearing outer ring, and between an end face of the other end of bearing middle cover and bearing inner race, ball and retainer thereof are housed; Open two, three shallow oil ducts of spiral on the outer surface with needle roller body, roller body; On bearing middle cover, bearing outer ring, open two, three small through hole; Outside former bearing outer ring, add a dustproof encloser, and bearing outer ring contacts with the post surface, interior garden of outer cover with the long radius sphere.
The advantage of the two-layer compound needle bearing that the present invention proposes is tangible, owing to the needle roller of single belt retainer is changed into the needle roller body of bilayer zone retainer, and between two-layer needle roller body, install a bearing middle cover additional to separate, thereby make the once rolling of original needle roller body become twice rolling, the Rolling velocity of every layer of needle roller body is descended greatly, load is uniform, and the comprehensive friction factor of bearing reduces greatly; At the two ends of bearing middle cover and an end of bearing inner race, two groups of rollers, ball and retainers thereof are housed, between the interior edge face of bearing outer ring to bear thrust load; Become twice rolling from original once rolling, can reduce friction factor again; Owing to needle roller body, roller body outer surface are had two, three shallow oil ducts of spiral, and have two, three small through hole on bearing middle cover and the bearing outer ring, the lubricating condition of bearing is improved; Owing to add a dust-proof cover again outside bearing outer ring, bearing outer ring contacts with the interior garden post of dustproof encloser is surperficial with the long radius sphere, but bearing not only can prevent dust but also self-aligning.Very little through above-mentioned improved bearing integral wearing and tearing power consumption, the bearing capacity height, long service life, but self-aligning, running is steady, and limit speed is higher, can extensively be suitable for all kinds of load-carrying vehicles and machinery, can be designed to the tandem product of standard.
Be described in further detail with regard to embodiments of the invention below in conjunction with accompanying drawing, thereby more can embody details of the present invention and advantage.
