Abstract
The utility model discloses a bearing limiting structure, which comprises a shaft, a bearing arranged on the shaft, and a round clamping ring, wherein a concave cavity is formed at the outer edge of an inner wall of an inner ring of the bearing; a clamping ring groove is formed on the shaft at the position corresponding to the concave cavity; and the round clamping ring is embedded in to the clamping ring groove and is in tight cling with the inner wall of the concave cavity of the inner ring of the bearing. In order to solve the problem that a current bearing limiting structure is large in axial space occupation and is longer in the overall axial length of a transmission, and the mounting of other parts is affected, the utility model provides the bearing limiting structure which is less in axial space occupation, shorter in the overall axial length of the transmission and does not affect the mounting of other parts.
Description
Technical field
The utility model relates to automotive transmission axle assembly technical field, relates in particular to a kind of bearing limit structure.
Background technique
Bearing is arranged on when working on axle, generally limit structure need to be set, and prevents bearing occurrence positions slippage or slippage in running.At present, the bearing axial limit structure on the transmission shaft assembly is generally to open an annular groove on the outer end journal of bearing inner race, then carries out axial limiting with rectangle or square snap ring.As shown in Fig. 2, such Standard is more difficult, and can take certain axial space, affects the whole axial length of speed changer, has increased the overall weight of speed changer, also affects the installation of other component.
Summary of the invention
The utility model accounts for axial space in order to solve present bearing limit structure, increase the whole axial length of speed changer, affect the problem that other component are installed, proposes that a kind of to account for axial space few, reduce the whole axial length of speed changer and other component installed the bearing limit structure that affects.
To achieve these goals, the utility model is by the following technical solutions:
A kind of bearing limit structure of the present utility model, comprise axle, be arranged on the bearing on axle, an and round clasp, the bearing inner race inner wall outside edge of described bearing is provided with a cavity, on described axle, the respective cavities position is provided with an annular groove, and round clasp is embedded in annular groove, is close to bearing inner race cavity inwall.By a cavity is set on the bearing inner race inwall, when making the spacing rigid bearing of round clasp, can be partially submerged in the bearing inner race inwall, be exposed at external lateral portion axially taking up room for axle thereby reduce, and then can shorten the length of axle, alleviate the overall weight of speed changer, for more spaces are vacateed in the installation of other component.
As preferably, described cavity cross section is one 1/4 circle.Be beneficial to the round clasp cooperation, increase surface of contact, make spacing more stable.
As preferably, described annular groove cross section is one 1/2 circle.Be beneficial to the round clasp cooperation, increase surface of contact, make spacing more stable.
As preferably, cavity cross section and annular groove cross section consist of one 3/4 circle.Make cavity and annular groove aligned in position, be convenient to round clasp and install, fix.
As preferably, the handing-over limit of described cavity and bearing inner race outer side surface is provided with fillet.Be convenient to installation, the dismounting of round clasp.
As preferably, the handing-over limit of described annular groove and axial plane is provided with fillet.Be convenient to installation, the dismounting of round clasp.
As preferably, described round clasp cross section is circular.Adopting cross section is circular round clasp, compared to rectangle or square snap ring, has advantages of installation, convenient disassembly.
As preferably, 1/4 circle of cavity cross section and 1/2 circle of annular groove cross section are identical with the circle radius of round clasp cross section.Can increase the surface of contact of round clasp and cavity and annular groove like this, make spacing more stable.
Therefore, the utlity model has following beneficial effect: (1) snap ring major part is embedded in bearing inner race and axle, reduces axially to take up room; (2) can reduce the whole axial length of speed changer, alleviate the speed changer overall weight; (3) technique is simple, easy to process.
