Abstract
The utility model relates to a novel automobile water pump bearing assembly which comprises a bearing, a connection side board, a middle shaft and a water pump impeller. The bearing comprises an outer circle, an inner circle, a roller and a holding frame, wherein the roller and the holding frame are arranged between the outer circle and the inner circle. One end of the middle shaft is fixedly connected with the water pump impeller, and the other end, opposite to the water pump impeller, of the middle shaft is fixedly connected with the center of the connection side board. A round outer edge is arranged on the connection side board, and the round outer edge is welded and fixed with the inner wall of one end of the outer circle. An inner circle end face, corresponding to one end of the connection side board, of the bearing is lower than an outer circle end face. The novel automobile water pump bearing assembly has the advantages of being simplified in production processes, high in efficiency and low in cost.
Description
Technical field
The utility model relates to a kind of new automobile water pump bearing assembly.
Background technique
The auto pump bearing assembly, generally include bearing, connect side plate, jack shaft and water pump vane, described bearing comprises outer ring, inner ring, is arranged on roller and retainer between outer ring and the inner ring, described jack shaft one end is fixedlyed connected with water pump vane, and the relative water pump vane the other end of jack shaft connects with the center fixation that is connected side plate.Therefore the exigent stationarity of the rotation of the water pump vane of auto pump bearing assembly, has the higher requirement of ratio to the combination that connects side plate and bearing.When existing auto pump bearing assembly is produced, in order to prepare to connect the fit dimension of side plate, to the influence of outer ring size, process an outer ring step earlier separately after the elimination product local annealing; In order to reduce the hardness of outer ring mating part, the riveting of being convenient to road, back assembling connection side plate operation grinds and closes, to outer ring matching part local annealing then; Install again and connect side plate; At last with the outer ring be connected the side plate riveting and grind and to close.Thereby existing auto pump bearing assembly, there is the production procedure complexity, inefficiency, the shortcoming that cost is higher.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of production procedure simplification, efficient is higher, cost is lower new automobile water pump bearing assembly.
For achieving the above object, the utility model provides following technological scheme: a kind of new automobile water pump bearing assembly, comprise bearing, connect side plate, jack shaft and water pump vane, described bearing comprises the outer ring, inner ring, be arranged on roller and retainer between outer ring and the inner ring, described jack shaft one end is fixedlyed connected with water pump vane, the relative water pump vane the other end of jack shaft connects with the center fixation that is connected side plate, described connection side plate is provided with circular outer rim, one end inwall of described circular outer rim and described outer ring welds fixing mutually, and the corresponding inner ring end face that connects side plate one end of described bearing is lower than cycle surface.
By adopting technique scheme, cancel outer ring step of traditional independent processing, outer ring matching part local annealing, outer ring and be connected production processes such as side plate riveting stone roller closes, thereby simplified production procedure, improved manufacturing efficiency, reduced cost of production; And the corresponding inner ring end face that connects side plate one end of described bearing is lower than cycle surface, makes that connecting side plate can better match with the outer ring inwall.
The utility model further arranges: described circular outer rim is fixedlyed connected by laser bonding with the inwall of described outer ring.
By adopting technique scheme, make that the inwall of circular outer rim and outer ring can strong bonded.
The utility model further arranges: described connection side plate center is provided with cylindrical sleeve, one end of described jack shaft matches fixing with cylindrical sleeve, the other end of jack shaft passes described bearing and extends to bearing to connect the side plate the other end relatively outer and fixedly connected with described water pump vane, and the corresponding retainer two ends are respectively arranged with seal ring between described outer ring and the inner ring.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model example structure sectional view.
Embodiment
Referring to accompanying drawing 1, the disclosed auto pump bearing assembly of the utility model, comprise bearing 1, connect side plate 2, jack shaft 3 and water pump vane 4, described 1 bearing comprises outer ring 101, inner ring 102, be arranged on roller 103 and retainer 104 between outer ring 101 and the inner ring 102, described jack shaft 3 one ends are fixedlyed connected with water pump vane 4, jack shaft 3 relative water pump vane 4 the other ends connect with the center fixation that is connected side plate 2, described connection side plate 2 is provided with circular outer rim 201, one end inwall of described circular outer rim 201 and described outer ring 101 welds fixing mutually, and described bearing 1 corresponding inner ring 102 end faces that connect side plate 2 one ends are lower than outer ring 101 end faces.By adopting technique scheme, cancel outer ring step of traditional independent processing, outer ring 101 matching part local annealings, outer ring 101 and be connected production processes such as side plate 2 rivetings stone roller closes, thereby simplified production procedure, improved manufacturing efficiency, reduced cost of production; And inner ring 102 end faces that should connect side plate 2 one ends are lower than outer ring 101 end faces, make that connecting side plate 2 can better match with outer ring 101 inwalls.
Present embodiment further arranges: described circular outer rim 201 is fixedlyed connected by laser bonding with the inwall of described outer ring 101.By adopting technique scheme, make that circular outer rim 201 and the inwall of outer ring 101 can strong bonded.Further preferred, the mode that adopts no dielectric laser to weld is weldingly connected with outer ring 101 fitting surfaces connecting side plate 2, during welding laser alignment is connected side plate 2 and outer ring 101 cooperations, welds under the protection of argon gas.
Present embodiment is further preferred, described connection side plate 2 centers are provided with cylindrical sleeve 202, one end of described jack shaft 3 matches fixing with cylindrical sleeve 202, the other end of jack shaft 3 passes described bearing 1 and extends to bearing 1 to connect side plate 2 the other ends relatively outer and fixedly connected with described water pump vane 4, and corresponding retainer 104 two ends are respectively arranged with seal ring 105 between described outer ring 101 and the inner ring 102.
