Abstract
The utility model relates to the technical field of switchgear, and especially a kind of ring main unit motor-operating mechanism, has transmission component, and transmission component comprises motor gear and operation gear of transmission that is meshed with it; Described operation gear is primarily of steel gear outer ring and fixedly embedded nylon inner sleeve composition in steel gear outer ring; The axis direction of described nylon inner sleeve offers endoporus, is provided with air chamber operating axis in endoporus.This ring main unit motor-operating mechanism, is not easy the phenomenon occurring that endoporus skids or tooth ruptures during operation gear normal running.
Description
Technical field
The utility model relates to the technical field of switchgear, especially a kind of ring main unit motor-operating mechanism.
Background technology
Motor-operating mechanism is the important component part in ring main unit, the operation principle of motor-operating mechanism normally: motor gear with operation meshed transmission gear, thus drive be arranged on operation gear on air chamber operating axis carry out a point closing operation.
But, due to existing operation gear employing is nylon material, operation gear is by after temperature, humidity effect, its dimensional tolerance and the strength of materials easily change, easily occur during operation gear normal running that endoporus skids or the phenomenon of tooth fracture, cause whole motor-operating mechanism can not normal deciliter.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of ring main unit motor-operating mechanism, is not easy the phenomenon occurring that endoporus skids or tooth ruptures during operation gear normal running.
The utility model solves the technical scheme that its technical problem adopts: a kind of ring main unit motor-operating mechanism, has transmission component, and transmission component comprises motor gear and operation gear of transmission that is meshed with it; Described operation gear is primarily of steel gear outer ring and fixedly embedded nylon inner sleeve composition in steel gear outer ring; The axis direction of described nylon inner sleeve offers endoporus, is provided with air chamber operating axis in endoporus.
Further specifically, the cross sectional shape of described endoporus is the square be rounded down, and the cross sectional shape of air chamber operating axis is suitable with endoporus and the square be also rounded down, and the rounding radii of air chamber operating axis is greater than the rounding radii of endoporus.
Further specifically, described steel gear outer ring is fixedly connected with by fastening bolt with nylon inner sleeve.
The beneficial effects of the utility model are: this ring main unit motor-operating mechanism, change the material of main part of operation gear into steel, the tooth operating gear is made to be not easy fracture when normal running, and close-fitting nylon inner sleeve in the main part of operation gear, make the overall dimensions tolerance operating gear affect by humiture little, ensure that the endoporus of operation gear does not occur skidding when normal running; But when transmission component generation clamping stagnation, the endoporus of operation gear but can skid, thus protection air chamber is injury-free.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, ring main unit motor-operating mechanism, has transmission component, and transmission component comprises the operation gear 2 of motor gear 1 initiatively and the transmission that is meshed with it; Operation gear 2 forms primarily of steel gear outer ring 21 and fixedly embedded nylon inner sleeve 22 in steel gear outer ring 21, and steel gear outer ring 21 is fixedly connected with by two fastening bolts 23 with nylon inner sleeve 22.
As shown in Figures 2 and 3, the axis direction of nylon inner sleeve 22 offers endoporus 221, is provided with air chamber operating axis 3 in endoporus 221.The cross sectional shape of endoporus 221 is the square be rounded down, and the cross sectional shape of air chamber operating axis 3 is suitable with endoporus 221 and the square be also rounded down, and the rounding radii of air chamber operating axis 3 is greater than the rounding radii of endoporus 221.
The operation principle of this ring main unit motor-operating mechanism is as follows:
Steel gear outer ring 21 is as the main part of operation gear 2, and its structural strength is comparatively strong, and when normal running, the tooth of operation gear 2 is not easy fracture.Nylon inner sleeve 22 is tight with at the inwall of steel gear outer ring 21, the overall dimensions tolerance of operation gear 2 affects less by humiture, the relative position between nylon inner sleeve 22 and air chamber operating axis 3 can be kept constant, and then ensure when normal running, there is not the phenomenon of skidding in the endoporus 221 of operation gear 2.But when transmission component generation clamping stagnation, the endoporus 221 of operation gear 2 but can skid, thus protection air chamber is injury-free.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
