Abstract
The invention discloses a motor end cap comprising an end cap body and a bearing installing base. The bearing installing base is arranged in the internal part of the end cap body. The bearing installing base comprises a connecting part and an installing part. The connecting part and the end cap body are detachably connected. The installing part comprises a shell, multiple spiral push rods and multiple clamping blocks which are corresponding to the spiral push rods in a one-to-one way. A circular arc shape used for clamping a bearing is formed by the internal sides of the multiple clamping blocks. The external side of each clamping block is provided with an open cavity. One end of each spiral push rod is connected with the open cavity in a clamping way via a connector. The spiral push rods outwardly extend to the external part of the shell from the connectors and are connected with the shell via threads. The motor end cap can be adjusted according to the sizes of different bearings so that only the size of the clamping circular arc formed by all the clamping blocks requires to be adjusted when the bearing is replaced, and reprocessing of a bearing cavity is avoided. Besides, the replacing process is more convenient and rapid and processing cost is reduced.
Description
Technical field
The present invention relates to technical field of motors, particularly relate to a kind of electric motor end cap.
Background technology
Existing motor end cap structure is mainly the cast structure that electric motor end cap and bearing chamber are integrated, and exploitation different model motor needs to develop different end cap casting dies, cannot be general when changing bearing type.
Application number be 201220575983.8 Chinese utility model patent disclose a kind of electric motor end cap, it, mainly through the bearing chamber of electric motor end cap is become detachable, changes bearing chamber separately as requested, without the need to again developing end cap.But the program still exists shortcoming: when changing bearing, still need again to process the bearing chamber adapted, and carrying out replacing assembling, improve production cost.
Summary of the invention
The present invention mainly solves technical problem existing in prior art, thus provides a kind of versatility good, the electric motor end cap that cost is low.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
Electric motor end cap provided by the invention, comprise end cap body and bearing mounting base, described bearing mounting base is positioned at described end cap body interior, described bearing mounting base comprises connecting portion and installation portion, described connecting portion is connected with described end cap body is detachable, described installation portion comprises housing, multiple spiral handspike and with described spiral handspike multiple grip block one to one, the inner side of multiple described grip block surrounds one for clamping the circular arc of bearing, and the outside of each described grip block is also provided with an atrium, one end of described spiral handspike is by a connector and the clamping of described atrium phase, wherein, described spiral handspike extends out to the outside of described housing from described connector position, and be threaded with described housing.
Further, the outside of described housing is also fixed with multiple projection, multiple described projection and described spiral handspike one_to_one corresponding, and is threaded with described spiral handspike.
Further, described spiral handspike is also provided with a rotating nut away from one end of described housing, is provided with a spring between described rotating nut and described projection.
Further, the shape of described housing is square, and multiple described spiral handspike is distributed on described foursquare surrounding.
Further, the width of described grip block is identical with the width of described bearing.
Further, described connecting portion and installation portion integrated molding.
Further, described connecting portion and described end cap body are threaded, and also scribble fluid sealant between described connecting portion and described end cap body.
Beneficial effect of the present invention is: the rectilinear movement being driven grip block by rotating screw push rod, the circular arc for clamping bearing that multi-disc grip block is surrounded, can regulate according to the size of different bearing, make it when changing bearing, only need to adjust the clamping circular arc size that all grip blocks are formed, which obviate machining bearing room again, and Renewal process is more convenient, reduces processing cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
