Abstract
The invention discloses a thin-wall bearing for rail transit. The thin-wall bearing comprises a body (1), an inner seal ring (2), a steel block (3), an outer seal ring (4), a seal ring (5), a retainer (6), a spring (7) and a dustproof shell (8), wherein the outer seal ring (4) is arranged at the top on the inner side of the body (1). The inner seal ring (2) is arranged at the middle-upper part on the inner side of the body (1). The steel block (3) is mounted between the inner seal ring (2) and the outer seal ring (4). The seal ring (5) is arranged at the bottom on the inner side of the body (1). The retainer (6) is arranged on the left side of the seal ring (5). The spring (7) and the dustproof shell (8) are arranged on the right side of the seal ring (5). The thin-wall bearing, provided by the invention, is complete in scheme, convenient to use, enhanced in bearing capacity, and low in possibility of damage.
Description
Technical field
The present invention relates to machinery accessory technical field, be specifically related to a kind of track traffic thin-wall bearing.
Background technique
Thin-walled type bearing achieves the bearing section of extremely thin type, also achieves the miniaturization of product, lightweight.The diversity of product extends its purposes scope.In order to obtain the low friction torque of bearing, high rigidity, good rotating accuracy, employ the steel ball of little external diameter.The use of quill shaft, ensure that the space of lightweight and distribution.Thin-walled type bearing achieves the bearing section of extremely thin type, also achieves the miniaturization of product, lightweight.The diversity of product extends its purposes scope.Thin-wall bearing precision is high, very quiet and bearing capacity is very strong, the bearing capacity of existing macropore thin-wall bearing is inadequate on the market, and after bearing uses a period of time, there will be retainer and steel ball causes wearing and tearing because of transition friction, have a strong impact on the working life of thin-wall bearing.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming, and a kind of track traffic thin-wall bearing is provided.
To achieve these goals, the present invention realizes by the following technical solutions: this track traffic thin-wall bearing comprises body, sealing inner ring, bloom, sealed outer ring, seal ring, retainer, spring and dustproof shell, the inside top of described body arranges sealed outer ring, the middle and upper part, inner side of body arranges sealing inner ring, between sealing inner ring and sealed outer ring, bloom is installed, the inside bottom of body arranges seal ring, wherein, on the left of seal ring, retainer is set, spring and dustproof shell are set on the right side of seal ring.
Preferably, described sealing inner ring and sealed outer ring are rubber seal.
Preferably, described sealed outer ring is identical with the specification of seal ring.
Preferably, the volume of described sealing inner ring is 1.2 ~ 1.5 times of the volume of sealed outer ring.
Preferably, described spring is engineering spring.
The invention has the beneficial effects as follows: scheme is complete, easy to use; Bearing capacity is enhanced; Not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of reference character in figure, 1, body, 2, sealing inner ring, 3, bloom, 4, sealed outer ring, 5, seal ring, 6, retainer, 7, spring, 8, dustproof shell.
