Summary of the invention
The utility model provides on a kind of worm gear excircle has only partial arc to be provided with the device for revolving and driving of tooth.For realizing the purpose of the utility model, can adopt following technological scheme.
Half gear device for revolving and driving comprises pedestal 1, pivoting support 2, worm screw 3, and said pedestal 1 is made up of axle housing 11 and 12 liang of parts of seat ring; The shaft axis of the shaft axis of axle housing 11 and seat ring 12 is orthogonal in the spatial position; Said worm screw 3 is installed in the axle housing 11 of pedestal 1, said pivoting support 2 comprise inner ring 21, external toothing 22 and be embedded at inner ring 21 and external toothing 22 between ball 23, external toothing 22 is provided with some installation screws; Inner ring (21) is fixed on the top of the seat ring 12 of pedestal 1; It is characterized in that the partial arc of external toothing 22 excircles is provided with tooth, the tooth of external toothing 22 and worm screw 3 engagements.
The corresponding angle of circular arc that external toothing 22 excircles are provided with tooth in the technique scheme can be selected 120o, 180o, 270o etc. for use usually for be less than the arbitrarily angled of 360o greater than 0o.
For the excessive situation of rotation that prevents that external toothing 22 from possibly occur when moving; In the technique scheme limit stoper 4 can also be set in the appropriate location of seat ring 12; Limit stoper can adopt buffer stopper or limit switch; Guarantee that external toothing is rotated in the predetermined scope, position transducer can also be set, with the angle of accurately measuring external toothing rotation or the position of stop.
In order to strengthen the waterproof and dustproof performance of the utility model; Top board 5 can also be set; Said top board 5 is provided with and external toothing 22 is installed the corresponding hole of screws, and top board 5 is installed on the top of external toothing 22 and inner ring 21, between said top board 5 and the seat ring 12, be provided with seal ring 6 between inner ring 21 and the external toothing 22; Said seal ring 6 can adopt y-type seal ring, Ο shape seal ring or lip-type seal circle, preferred lip-type seal circle.
The external toothing that the utility model utilization has only the part circumference to be provided with tooth has substituted the external toothing that full-depth tooth is set in the general device for revolving and driving; Both satisfied the occasion of some specific (special) requirements and used, and can reduce amount of finish again, enhance productivity, reduce cost of production, economize on resources.
