Abstract
The invention relates to a fixing device for a combined bearing on a motor and belongs to the field of motor manufacturing. The fixing device comprises a front cover, a rear cover and a bearing. The fixing device is characterized in that the bearing has a combined structure, wherein the structure comprises an outer sleeve and a bearing; the bearing is embedded into the outer sleeve and is in close fit with the outer sleeve; the bearing of the combined structure is assembled in the space formed by the front cover and the rear cover ; a fixing clamp is tightly matched and mounted with the end part of the outer sleevethe outer sleeve of the bearing; the fixing clamp is in close fit with the front cover or the rear cover; the outer sleeve is a drum-shaped outer sleeve made of alloy powder; the fixing clamp is circular-shaped; zigzag sharp bulges are arranged on the outer periphery of the circular-shaped fixing clamp; hollow sharp bulges are uniformly distributed on the periphery of the inner circle of the circular-shaped fixing clamp; and the bearing and the shaft sleeve are made of alloy powder. The fixing device has the advantages that the bearing or shaft sleeve on the motor is made of alloy powder, and meanwhile, a split type combined structure is adopted, the production cost is greatly reduced by more than 60%, and the fixing device is suitable for being applied to a massage rod motor in fitness equipment in bulk.
Description
Technical field
The present invention relates to field of motor manufacturing, particularly be applicable to combination bearing fixture on the motor more than 60% of reducing production costs on the body-building apparatus.
Background technology
Motor of the prior art generally all adopts the bulk metal bearing, and manufacturing cost is than higher.Also have on the integrated powder of the employing alloy bearing cost and also height, and useful life is influenced.Because Bearing Installation does not have the fixture that prevents axial move left and right is set in front and rear covers, motor performance is affected in addition.
Summary of the invention
The objective of the invention is provides combination bearing fixture on a kind of motor that can reduce production costs more than 60% to above-mentioned defective.
Technical scheme of the present invention is a combination bearing fixture on the motor, comprises protecgulum, bonnet, bearing, it is characterized in that described bearing is a combining structure, and this structure comprises overcoat and bearing, and bearing embeds tight fit in the overcoat; The combining structure bearing is assemblied in protecgulum and the bonnet, and the overcoat end close-fitting in the bearing is equipped with geometrical clamp, geometrical clamp and protecgulum or bonnet close-fitting.
Described overcoat is that powder metallurgy is processed the cydariform overcoat; Described geometrical clamp is an annular, and it is protruding that annular geometrical clamp excircle is provided with the zigzag point, and it is protruding that inner ring is evenly distributed in hollow point.
Described bearing is an axle sleeve, and bearing and axle sleeve are that powder alloy material is processed.。
Advantage of the present invention is that motor upper bearing (metal) or axle sleeve adopt powder alloy material to process, and adopts split combination structure simultaneously, and reducing production costs greatly reaches more than 60%.Can adapt to the application of massage bar motor in the body-building apparatus in enormous quantities.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the fixed folder structure sketch map.
Among the figure: 1-protecgulum, 2 bearings, 3-overcoat, 4-geometrical clamp, the hollow point of 5-are protruding.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing with optimal way.
With reference to Fig. 1, Fig. 2, innovative point of the present invention is that bearing 2 is combining structures, and this structure comprises overcoat 3 and bearing 2, and bearing 2 embeds tight fit in the overcoat 3; Combining structure bearing 2 is assemblied in protecgulum 1 and the bonnet, and the overcoat 3 end close-fittings in the bearing 2 are equipped with geometrical clamp 4, geometrical clamp 4 and protecgulum 1 or bonnet close-fitting.Overcoat 3 is that powder metallurgy is processed the cydariform overcoat; Described geometrical clamp 4 is annulars, and it is protruding that annular geometrical clamp 4 excircles are provided with the zigzag point, and inner ring is evenly distributed in hollow point protruding 5.Bearing 2 also can substitute with axle sleeve, and bearing and axle sleeve all can adopt powder metallurgy to process.
Practical implementation is following: like Fig. 1, be protecgulum 1 position on the motor, the bonnet position is identical with protecgulum position structure.Bearing 2 is installed in the protecgulum 1, and the structure of bearing 2 is taked combining structure, just adopts split type; Bearing 2 is embedded tight fit in the overcoat 3, and overcoat 3 is made cydariform, the end of its external sleeve 3; Here be rearward end, have geometrical clamp 4 and protecgulum 1 rear aperture place tight fit to install, geometrical clamp 4 usefulness sheet metals are made annular; It is protruding that annular geometrical clamp 4 excircles are provided with the zigzag point, and inner ring is evenly distributed in hollow point protruding 5.There are sharp protruding place and circumferential edges to process concave shaped on geometrical clamp 4 excircles, flexible when sharp protruding place is cooperated with protecgulum 1.Just the anchor ring of geometrical clamp 4 is like pot cover appearance edge indent.Geometrical clamp 4 inner rings have been processed sky apex of the heart convex and have been distributed, and this position mainly is to make overcoat 3 and geometrical clamp 4 close-fittings chimeric.The material of bearing 2, axle sleeve and overcoat 3 all can adopt powder metallurgy to process; Also can adopt overcoat is that powder metallurgy is processed, and bearing 2 or axle sleeve adopt metal to process.The structure of bonnet is identical with the structure of protecgulum 1, and only the opening of bonnet is surface motor inner core left when bonnet is installed on the motor shaft.
Claims (3)
1. combination bearing fixture on the motor comprises protecgulum, bonnet, bearing, it is characterized in that described bearing is a combining structure, and this structure comprises overcoat and bearing, and bearing embeds tight fit in the overcoat; The combining structure bearing is assemblied in protecgulum and the bonnet, and the overcoat end close-fitting in the bearing is equipped with geometrical clamp, geometrical clamp and protecgulum and bonnet close-fitting.
2. by combination bearing fixture on the described motor of claim 1, it is characterized in that described overcoat is that powder metallurgy is processed the cydariform overcoat; Described geometrical clamp is an annular, and it is protruding that annular geometrical clamp excircle is provided with the zigzag point, and it is protruding that inner ring is evenly distributed in hollow point.
