Abstract
The utility model discloses a planetary wheel component, comprising a planetary wheel (1) and a sliding bearing (2); the sliding bearing (2) is assembled in the bearing hole of the planetary wheel (1); and the planetary wheel component is characterized in that a layer of fixing agent (3) is installed between the inner wall of the bearing hole of the planetary wheel (1) and the outer wall of the sliding bearing (2). The interference rate of the sliding bearing assembled in the bearing hole of the planetary wheel is 0.01-0.025 to reduce the magnitude of interference, and the planetary wheel and the sliding bearing are fixedly assembled together by using the fixing agent so that the fixing effect of interference magnitude assembly can be reached; in the process of assembling, the planetary wheel is not easy to deform, the assembling is more convenient, thereby improving the assembling efficiency, reducing waste products produced in the process of assembling and greatly reducing the production cost.
Description
Technical field
The utility model relates to a kind of planet wheel, especially the planetary wheeling assembly in a kind of planet wheel using process.
Background technique
At present, the planetary wheeling assembly that planet wheel and sliding bearing are formed is by frock sliding bearing to be press fit in the bearing hole of planet wheel in assembly process.Interference fit between planet wheel and the sliding bearing, in order to guarantee firm being assemblied in the planet wheel of sliding bearing energy, magnitude of interference is just bigger.This just makes after assembling is pressed into sliding bearing, squeezes easily and hinders the sliding bearing matching surface, can cause situations such as assembling back sliding bearing Internal Hole Deformation, coaxality difference; Also relatively more difficult when press-fiting assembling, efficiency of assembling is lower, produces a collection of product and can produce a large amount of waste products.
The model utility content
The planetary wheeling assembly that provides a kind of assembly relation good is provided technical problem to be solved in the utility model.
The technical solution of the utility model is as follows: a kind of planetary wheeling assembly, comprise planet wheel and sliding bearing, described sliding bearing is assemblied in the bearing hole of described planet wheel, and its key is: be provided with the agent of one deck fixing between the bearing hole inwall of described planet wheel and the sliding bearing outer wall.Reduced magnitude of interference, utilized the fixing agent planet wheel and firm being assembled together of sliding bearing.
Above-mentioned fixing agent is 1620 cylindrical part fixing agent.
Beneficial effect: the interior magnitude of interference of bearing hole that sliding bearing is assemblied in planet wheel is 0.01～0.025, has reduced magnitude of interference, utilizes the fixing agent with planet wheel and firm being assembled together of sliding bearing, can reach the firm effect of magnitude of interference assembling; In the assembly process, planet wheel is not yielding, assembles conveniently, has improved the efficient of assembling; Reduced the waste product that produces in the assembly process, greatly reduced and manufacture a finished product.
Description of drawings
Fig. 1 is a structure intention of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of planetary wheeling assembly is made up of planet wheel 1 and sliding bearing 2, and described sliding bearing 2 is assemblied in the bearing hole of described planet wheel 1, is provided with one deck fixing agent 3 between the bearing hole inwall of described planet wheel 1 and sliding bearing 2 outer walls.1620 cylindrical part fixing agent are selected in fixing agent 3 for use.
Claims (2)
1. planetary wheeling assembly, comprise planet wheel (1) and sliding bearing (2), described sliding bearing (2) is assemblied in the bearing hole at described planet wheel (1) center, it is characterized in that: scribble fixing agent layer (3) between the bearing hole inwall of described planet wheel (1) and sliding bearing (2) outer wall.
