Abstract
The utility model relates to a motorised valve motor's double end cap structure. According to the utility model, an internal end cap and an external end cap are fixed on an end portion of a motor stator through bolts, and the internal end cap is provided with a window. By the adoption of the double end cap structure, it is guaranteed that secondary sealing of the internal end cap can be realized through the external end cap when the window of the internal end cap opens. Thus, a motor can reach a protection grade of IP67.
Description
Technical field
The utility model belongs to the motor manufacturing technology field, relates to a kind of end cover structure, the double-deck end cover structure of especially a kind of electrically operated valve motor.
Background technology
In the prior art, the structure of motor has only a front end housing (commutator end), end cap has window, adjust the brush holder position by window in the process of the test, observation motor runnability can reach general (below the IP44) requirement of shelter at window motor encapsulation cover plate or shutter after test finishes;
But, for the product requirement degree of protection is IP67, if still adopt an existing front end housing structure, then need after test is finished, the motor front end housing to be pulled down again (many operations), smear fluid sealant at the seam end face, encapsulate after the assembling once more and (need check machinery, electric property after the assembling once more, as the need adjustment, need seal once more, assemble, and degree of protection is difficult for reaching the IP67 requirement).
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of electrically operated valve motor double-deck end cover structure, and this end cover structure adopts two-layer stratigraphic structure, can effectively solve the problem of the assembling of motor performance adjustment and motor secondary, sealing.
The purpose of this utility model solves by the following technical programs:
The double-deck end cover structure of this electrically operated valve motor has internal layer end cap and outer end cap in the end of motor stator by bolt, offers window on the described internal layer end cap.
Above-mentioned outer end cap is placed on the internal layer end cap, and outer end cap adopts bucket formula hermetically-sealed construction.
Above-mentioned outer end cap seam end face is coated with the envelope fluid sealant.
Above-mentioned internal layer end cap and outer end cap are radially staggering in the fixed position of the end of motor stator.
Adopt little matched in clearance between the interior circle of the cylindrical of above-mentioned internal layer end cap and outer end cap.
The utlity model has following beneficial effect:
The double-deck end cover structure of electrically operated valve motor of the present utility model adopts the two-layer equation end cover structure, guarantees can make outer end cap that the internal layer end cap is carried out secondary seal in internal layer end cap windowing, makes motor can reach the degree of protection of IP67.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, the double-deck end cover structure of electrically operated valve motor of the present utility model is by bolt internal layer end cap 9 and outer end cap 10 to be arranged in the end of motor stator, offers window on the internal layer end cap 9.Described outer end cap 10 is placed on the internal layer end cap 9, and outer end cap 10 adopts bucket formula hermetically-sealed construction.Outer end cap 10 seam end faces are coated with the envelope fluid sealant.
Internal layer end cap 9 and outer end cap 10 are radially staggering in the fixed position of the end of motor stator.State between the interior circle of the cylindrical of internal layer end cap 9 and outer end cap 10 and adopt little matched in clearance.
Assembling process of the present utility model is as follows:
1. the internal layer end cap 9 that will have window is assemblied on the stator by bolt 7 and pad 8;
2. carry out electrical performance test, adjust brush holder 11 positions as need, then unclamp the hold-down screw parts 11,12,2 of brush holder 13, brush holder 13 positions are adjusted in rotation, and are then fixing; Motor operation spark can be observed by the window of internal layer end cap 9;
3. after the pass the test, be coated with the envelope fluid sealant, be assemblied on the stator by bolt 3 and pad 4 at outer end cap 10 seam end faces; Because of outer end cap 10 adopts bucket formula hermetically-sealed construction, can reach seal request after the assembling.
In a word, double-deck end cover structure has solved the problem of the assembling of motor performance adjustment and motor secondary, sealing
