Abstract
The invention discloses a self-aligning roller bearing for a traction machine. The self-aligning roller bearing for the traction machine comprises a body (1), a sealing ring a (2), a sealing ring b (3), a retainer (4), a ball (5) and a sealing ring c (6), wherein the sealing ring b (3) is arranged on the top of the body (1); the sealing ring a (2) is arranged on the middle upper part of the body (1); the retainer (4), the ball (5) and the sealing ring c (6) are arranged between the sealing ring a (2) and the sealing ring b (3); and the specification of the sealing ring a (2) is the same with that of the sealing ring b (3). The bearing capacity of the self-aligning roller bearing for the traction machine is improved, moreover, a sealing structure is adopted, and long-service-life lubricating grease is injected in the bearing in advance, so that the maintenance cycle is prolonged greatly.
Description
Technical field
The present invention relates to machinery accessory technical field, be specifically related to a kind of hoist machine selfaligning roller bearing.
Background technique
The main shaft of existing elevator hoist machine adopts two kinds of bearings usually, its structure as shown in Figure 1, wherein, a kind of deep groove ball bearing with dual face seals, advantage is that bearing carries seal arrangement, does not need to arrange sealing configuration at bearing periphery, and bearing pre-fill lubricating grease in a pre-installation, but shortcoming is that the bearing capacity of bearing is little, lubricating grease can not be mended when the maintenance of bearing.And some selfaligning roller bearings, advantage is that bearing capacity is large, and shortcoming at bearing periphery design seal arrangement, and regularly will will mend lubricating grease.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming, and a kind of hoist machine selfaligning roller bearing is provided.
To achieve these goals, the present invention realizes by the following technical solutions: this hoist machine selfaligning roller bearing comprises body, seal ring a, seal ring b, retainer, ball and seal ring c, the top of described body arranges seal ring b, the middle and upper part of body arranges seal ring a, arranges retainer, ball and seal ring c between seal ring a and seal ring b; Described seal ring a is identical with the specification of seal ring b; Described ball is positioned in the middle of retainer and seal ring c; Described seal ring a, seal ring b and seal ring c are rubber seal.
Preferably, described body is cuboid.
Preferably, described retainer is made up of stainless steel.
Preferably, described ball is stainless steel ball.
Preferably, the volume of described seal ring a is 1/10 of bulk volume.
The invention has the beneficial effects as follows: the bearing capacity of bearing gets a promotion, and, adopt sealing configuration, and long-life lubricating grease of annotating in advance, greatly extend service cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of reference character in figure, 1, body, 2, seal ring a, 3, seal ring b, 4, retainer, 5, ball, 6, seal ring c.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
This hoist machine with selfaligning roller bearing to achieve these goals, the present invention realizes by the following technical solutions: this hoist machine selfaligning roller bearing comprises body 1, seal ring a2, seal ring b3, retainer 4, ball 5 and seal ring c6, the top of described body 1 arranges seal ring b3, the middle and upper part of body 1 arranges seal ring a2, arranges retainer 4, ball 5 and seal ring c6 between seal ring a2 and seal ring b3; Described seal ring a2 is identical with the specification of seal ring b3; Described ball 5 is positioned in the middle of retainer 4 and seal ring c6; Described seal ring a2, seal ring b3 and seal ring c6 are rubber seal; Body 1 is cuboid; Retainer 4 is made up of stainless steel; Ball 5 is stainless steel ball; The volume of seal ring a2 is 1/10 of body 1 volume.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
