Abstract
The utility model discloses a secondary-deceleration-brushless-motor box body which includes a cylindrical brushless motor casing, a rear end cover and a front end cover. An end face at one side of the casing is opened. The opened position is sealed through the rear end cover, and an end face at the other side of the casing cooperates with the front end cover so as to form a cavity used for fixing a secondary reducing mechanism. The end face of the casing and the front end cover structure are enabled to form the casing of the secondary reducing mechanism so that the prior structure, in which the motor casing and secondary reducing casing are arranged in a separated manner, is simplified and thus the secondary deceleration brushless motor is smaller in volume.
Description
Technical field
The utility model relates to motor component, particularly a kind of casing that is applicable to double reduction brushless electric machine.

For above-mentioned deficiency, applicant has invented a kind of casing that is applicable to substituting existing double reduction transmission brushless electric machine housing, to address the above problem.
Utility model content
In view of this, the utility model provides a kind of double reduction brushless electric machine casing, by rational structure, arranges, and has solved large, the baroque problem of existing double reduction transmission brushless electric machine volume.
The utility model solves the problems of the technologies described above by following technological means:
Double reduction brushless electric machine casing of the present utility model, comprise columniform brushless electric machine casing, rear end cap and front end housing, one side end face of described casing is uncovered, this open-mouth is by rear end cap cap seal, and the opposite side end face of described casing coordinates with front end housing and is formed for the fixedly cavity of two reduction gear.
Further, on described casing end face, offer the first groove for wheel shaft one end of axial restraint two reduction gear idler gear, on described front end housing, over against position, be provided with one for the second groove of the wheel shaft other end of axial restraint two reduction gear idler gear with described the first groove.
Further, the middle part of described front end housing is provided with centre bore.
Further, on described casing, on the end face of non-uncovered one end, be provided with many floors that radially extend.
Further, on the medial surface of described rear end cap and front end housing, be respectively arranged with many floors that radially extend.
The beneficial effects of the utility model: double reduction brushless electric machine casing of the present utility model, comprise columniform brushless electric machine casing, rear end cap and front end housing, one side end face of described casing is uncovered, this open-mouth is by rear end cap cap seal, and the opposite side end face of described casing coordinates with front end housing and is formed for the fixedly cavity of two reduction gear.By the end face of casing and front end housing structure being formed to the casing that two reduction gear is installed, simplified the structure of motor case and secondary speed reduction box split setting in the past, make double reduction brushless electric machine volume smaller and more exquisite.
