Description
Technical field
The utility model belongs to machine field, particularly relates to a kind of insulation system of electric motor end cap.
Background technology
Electric motor end cap is the vitals in motor product, and how are its project organization, manufacturing technology level, has very important impact to the technical grade, performance, operational reliability, useful life, energy consumption, noise etc. of motor product.And the motor product end cap of China, adopt the metal material manufactures such as steel for a long time, Gu this cannot solve shaft current that motor produces in running in end cap the galvano-cautery that produces of the bearing that is equipped with, working face smooth for bearing is corroded spot is innumerable, rough and uneven in surface, the energy consumption causing motor to run increases, noise increases, shortening in useful life, and disagrees with the energy-saving and environmental protection policy of country.In order to solve this long-standing technical barrier, some motor manufacturer just utilizes and metal end lid is resolved into inside and outside end cap two parts, separates therebetween with insulating barrier, makes its insulation each other, to block shaft current.Its basic structure as shown in Figure 1.Be easy to just to find out that this structure needs multiple insulated tube and multiple insulating washer from Fig. 1, and its structure is particularly complicated, installation effectiveness is low.
Utility model content
The purpose of this utility model be complicated for the insulation system of existing electric motor end cap, installation effectiveness is low and the insulation system of the electric motor end cap that a kind of novel insulation effect is good, structure is simple, installation effectiveness is high that provides.
The utility model is achieved by the following technical solution:
The insulation system of electric motor end cap, comprises outer end cap and inner end cap, and outer end cap is that metal material is made, and described inner end cap comprises SMC sheet stock, and arranges fiberglass gridding cloth between adjacent two sheet stocks, and is formed by mould compacting.
Outer end cap has a hole slot, and inner end cap is embedded in the hole slot of outer end cap, and inner end cap is fixedly connected with outer end cap by jockey.
The hole slot upper end of described outer end cap has one recessed in the ring-shaped depression part of outer end cap upper surface, have circumference extend in inner end cap upper end and be placed in the annular protrusion edge in outer end cap ring-shaped depression part, the annular protrusion edge that jockey runs through in inner end cap is fixedly connected with outer end cap.Described jockey is bolt.
The beneficial effects of the utility model: the utility model new motor end cap compares with the electric motor end cap of traditional structure that its insulating reliability is high, nargin is large, the insulation distance of the electric motor end cap of the application is large, be 6.8 ~ 10 times of the former main insulating structure, the reliability of insulation is greatly improved; The utility model end cover structure is simple, and the electric motor end cap of this structure only just can realize insulation function by insulation inner end cap, and traditional end cap will lean on main insulating layer, insulating washer, insulated tube jointly to realize its insulation function.Electric motor end cap of the present utility model is fewer than the former has used two kinds of parts totally 16; The utility model production process is few, and required parts are few, with short production cycle, and work efficiency is high, and labour intensity is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, the insulation system of electric motor end cap, comprises outer end cap 1 and inner end cap 5, and outer end cap 1 is made for metal material, and described inner end cap 1 comprises SMC, and (SMC is the one of composite material, fiberglass.Primary raw material is made up of GF (special yarn), MD (filler) and various auxiliary agent) sheet stock, and fiberglass gridding cloth is set between adjacent two sheet stocks, and formed by mould compacting, outer end cap 1 has a hole slot 2, inner end cap 5 is embedded in the hole slot of outer end cap 1, and inner end cap 5 is fixedly connected with outer end cap 1 by jockey 3.Hole slot 2 upper end of described outer end cap 1 has one recessed in the ring-shaped depression part 4 of outer end cap upper surface, have circumference extend in inner end cap 5 upper end and be placed in the annular protrusion edge 6 in outer end cap ring-shaped depression part, the annular protrusion edge that jockey runs through in inner end cap is fixedly connected with outer end cap.Described jockey is bolt.
This end cap is the insulated end cover replacing steel end cap, Gu this should have intensity high as far as possible.Due to the limited mechanical strength of common insulating material, single insulating material is only adopted to be difficult to realize.Determine to adopt composite insulation structure scheme for this reason, the utility model is the fiberglass gridding cloth placing impregnation between the sheet stock in the SMC moulding compound that intensity is higher, material base is become with the method lamination, then put in the special die of insulated end cover, through temperature-pressure, making it forming and hardening is high-strength insulating inner end cap.Its strength ratio only significantly improves by the insulation inner end cap that SMC moulding compound suppresses, and meets the electric motor end cap instructions for use of new construction.
This end cap only needs five kinds of parts to assemble, easy and simple to handle.And the insulation inner end cap in end cap only needs blanking, long-pending base, compacting, machine work to complete, its workpiece only has 10kg heavy, and every part construction only needs 90 minutes man-hour, thus the construction period of electric motor end cap is shortened dramatically, and work efficiency is higher.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection range of the present utility model.
