Abstract
The utility model relates to a low noise self -aligning roller bearing, including inner circle (1), outer lane (2) to and install biserial rolling element (3) between inner circle (1) and outer lane (2) through holder (4), holder (4) have lead ring (5), outer lane (2) raceway be single circular arc raceway, inner circle (1) raceway is the bi -arc raceway, bi -arc raceway section is smooth arc, rolling element (3) be the cydariform. Compared with the prior art, the utility model has the advantages of low vibration, low noise, good, the long service life of bearing capacity.
Description
Technical field
This utility model relates to a kind of self-aligning roller bearing, especially relates to a kind of low noise self-aligning roller bearing.
Background technology
Self-aligning roller bearing is to have the bearing assembling barrel shaped roller between the inner ring of two raceways and the outer ring that raceway is sphere, substantial radial load, also can bear the axial load of either direction simultaneously, self-aligning roller bearing has automatic aligning, bear the ability of the radial load of weight, be widely used in the various bad working environments such as metallurgy, mine, gear-box.
Bearing is in operation process, and except some between bearing parts, the motion of other all deviation ideal positions except motion intrinsic, required by function is referred to as bear vibration.When the Vibration propagation of rolling bearing is to radiating surface, vibrational energy converts pressure wave to, and blazing abroad through air dielectric is acoustic radiation again.The acoustic radiation that wherein 20 20000Hz parts can receive for human ear, is Noise of Rolling Bearing.
The vibration of bearing and noise control level are the accuracy of manufacture and advanced comprehensively the embodying of technique.Low noise, low vibration product can not only bring the comfort in use to client, and reliability can be improved, increase the service life.Therefore, domestic each bearing producer increasingly payes attention to the vibration of product, noise specification in recent years, shows the Con trolling index of deep groove ball bearing portion size section.But industry is interior less than the relevant criterion to the vibration of this series products, noise at present, it is relatively big that product noise level compares external imported product gap, and service life is relatively low.On aluminium milling train conveyer belt, such as apply self-aligning roller bearing 22216E/C3/W33, reliability requirement is higher, the bearing damage outside turn(a)round can not occur in 1 year.And the standard model bearing of existing manufacturer production can not meet customer requirement.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of and produce that noise is low, vibrate little low noise self-aligning roller bearing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of low noise self-aligning roller bearing, including inner ring, outer ring, and it is arranged on the biserial rolling element between inner ring and outer ring by retainer, described retainer is with lead ring, it is characterized in that, described outer ring raceway is single arc raceway, and inner ring raceway is duplex circular ares profile race, duplex circular ares profile race section is smooth arc, and described rolling element is cydariform.
Leave 2mm～10mm gap between described lead ring and inner ring, between lead ring and outer ring, leave 2mm～10mm gap.
Described retainer is window pressing cage.
Described retainer is the retainer adopting steel to make.
Described outer ring raceway chamfered edges is fillet.
Compared with prior art, this utility model has the advantage that
(1) outer ring raceway is single arc raceway, and inner ring raceway is duplex circular ares profile race, and duplex circular ares profile race section is smooth arc, without rib, thus effectively increasing the contact area of roller and raceway in bearing operation process, strengthens the bearing capacity of bearing.
(2) rolling element is cydariform, vibrates little, and noise is low.
(3) being respectively kept with 2mm～10mm gap between lead ring and inner ring and outer ring, noise is low, meets high-end user demand.
(4) retainer is window stamped steel retainer, and stationarity is high, long service life.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.The present embodiment is carried out premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
A kind of low noise self-aligning roller bearing, including inner ring 1, outer ring 2, and being arranged on the biserial rolling element 3 between inner ring 1 and outer ring 2 by retainer 4, described retainer 4 is with lead ring 5, described outer ring 2 raceway is single arc raceway, inner ring 1 raceway is duplex circular ares profile race, and duplex circular ares profile race section is smooth arc, and described rolling element 3 is in cydariform, curved of rolling element 3 and inner ring 1 curve surface of raceway are fitted completely, rolling element 3 surface roundness tolerance is 0.6 μm, vibrates little, and noise is low.
All leaving 2mm～10mm gap between described lead ring 5 and inner ring 1 and outer ring 2, noise is low, meets high-end user demand.
Described retainer 4 is window stamped steel retainer, and stationarity is high, long service life.
Described outer ring 2 raceway chamfered edges is fillet, to reduce damage of colliding with.
Claims (5)
1. a low noise self-aligning roller bearing, including inner ring (1), outer ring (2), and it is arranged on the biserial rolling element (3) between inner ring (1) and outer ring (2) by retainer (4), described retainer (4) is with lead ring (5), it is characterized in that, described outer ring (2) raceway is single arc raceway, inner ring (1) raceway is duplex circular ares profile race, duplex circular ares profile race section is smooth arc, and described rolling element (3) is in cydariform.
2. a kind of low noise self-aligning roller bearing according to claim 1, it is characterized in that, leave 2mm～10mm gap between described lead ring (5) and inner ring (1), between lead ring (5) and outer ring (2), leave 2mm～10mm gap.
