Abstract
The invention discloses an outer bearing cover structure, which comprises an outer cover body, wherein the outer cover body has a hollow structure; a plurality of solid bolt assembly parts and tapped oil filler hole parts are uniformly distributed on the periphery of the outer cover body, and are arranged at intervals. According to the outer bearing cover structure, the bolt assembly parts and the tapped oil filler hole parts are solid, and the other part is hollow, so that an oil storage space can be enlarged as much as possible, waste oil can be changed at one time when a motor is overhauled, and an intermediate oil drain link is eliminated; the outer bearing cover structure is simple and convenient to machine; moreover, an oil drain pipe is not required to be assembled, so that the outer bearing cover structure is low in cost.
Description
Technical field
The present invention relates to a kind of bearing end cover structure.
Background technology
At present, existing bearing end cover structure all adopts form as depicted in figs. 1 and 2.Refer to shown in Fig. 1 and Fig. 2, traditional bearing end cover structure comprises bearing end cover 10, on described bearing end cover 10, be processed with the oil duct 11 of a circle, described bearing end cover 10 install after with end cap formation shoe cream room, and the bottom of described bearing end cover 10 offers outage 12, on described outage 12, is connected with oil exit pipe, this structure is more complicated and heavy, oil reserve is few, and the man-hour that in production process, machining needs is more, and production cost is high; And when oil exit pipe and external fan assembling, easily interfere, give to produce to assemble and bring inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of bearing end cover structure, its have simple in structure, be convenient to processing, oil reserve is large and cost is low feature.The problems referred to above that exist to solve prior art middle (center) bearing enclosing cover.
For reaching this object, the present invention by the following technical solutions:
A bearing end cover structure, it comprises enclosing cover body, wherein, described enclosing cover body is hollow-core construction, and the periphery of described enclosing cover body is evenly equipped with several solid bolts assemblies portions and attacks oil filler point portion, described bolts assemblies portion and attack oil filler point portion interval and arrange.
Especially, the bottom of described enclosing cover body offers outage.
Especially, described enclosing cover body is formed by cast iron cast.
Especially, the bottom of described enclosing cover body is square structure, and top is circular configuration, and described bolts assemblies portion and attack oil filler point portion and be circular configuration forms quincuncial oil storage space in the top of described enclosing cover body, and square oil storage space is formed at bottom.
Especially, described bolts assemblies portion is set to four, described in attack oil filler point portion and be set to three.
Beneficial effect of the present invention is, compared with prior art described bearing end cover structure is solid section except reserving bolts assemblies portion and attacking oil filler point portion, other parts are hollow, can increase as far as possible oil storage space like this, owing to reserving as much as possible large oil storage space, can be in machinery check and repair, swap out waste oil is disposable, oil extraction link in the middle of saving.Not only simple in structure, be convenient to processing; And without assembly platoon oil pipe, cost is low.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate technical scheme of the present invention.
Refer to shown in Fig. 3 and Fig. 4, Fig. 3 is the schematic diagram of the bearing end cover structure that provides of the specific embodiment of the invention 1; Fig. 4 be in Fig. 3 B-B to profile.
In the present embodiment, a kind of bearing end cover structure comprises enclosing cover body 20, the bottom of described enclosing cover body 20 is square structure, top is circular configuration, and described enclosing cover body 20 is hollow-core construction, and the periphery on the top of described enclosing cover body 20 is evenly equipped with four solid bolts assemblies portions 21 and solid three and attacks oil filler point portion 22, wherein two bolts assemblies portions 21 are arranged at the both sides of described enclosing cover body 20 bottom square structures, attack oil filler point portion 22 one after the other intervals layouts for all the other two and described three, and described bolts assemblies portion 21 and attack oil filler point portion 22 and be circular configuration, in the top of described enclosing cover body 20, form quincuncial oil storage space, square oil storage space is formed at bottom.
Described enclosing cover body 20 is formed by cast iron cast, and wall thickness is 6 ㎜.
Above-mentioned threephase asynchronous machine bearing end cover structure is except reserving bolts assemblies portion 21 and attacking oil filler point portion 22 for solid section, other parts are hollow, can increase as far as possible oil storage space like this, whole processing coordinates with end cap, can process oil exit pipe according to customer requirement, also can not process outage, make bearing end cover processing save many process times, during assembling, also reduce the installation steps of oil exit pipe, and saved oil exit pipe.Owing to reserving as much as possible large oil storage space, can be in machinery check and repair, swap out waste oil is disposable, oil extraction link in the middle of saving.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
