Abstract
The invention relates to a transmission device for a small-scale motor. The transmission device includes a motor protection box and a box cover; a through hole corresponding to a transmission shaft of the motor is formed at the center of the box cover; the box cover sleeves the transmission shaft through the through hole so as to be in threaded connection with the motor protection cover; a circular positioning groove is formed at the side wall of the transmission shaft; the top end of the transmission shaft is sleeved with a transmission gear, the middle segment of the side wall of the transmission gear being provided with saw teeth; the top end of the transmission gear is provide with a circular protection sleeve which is used for protecting the saw teeth; a positioning hole corresponding to the positioning groove is formed at the lower end of the side wall of the transmission gear; and a positioning pin is inserted into the positioning hole so as to be in clamped connection with the positioning groove. The transmission device for the small-scale motor of the invention is provided with the gear protection sleeve and the positioning pin, and therefore, the antiskid performance of the transmission device can be greatly enhanced, and the service life of the gear can be prolonged.
Description
Technical field
The present invention relates to a kind of transmission device for micro-machine.
Background technology
The transmission structures of common micro-machine is simple, mostly directly by geared sleeve on power transmission shaft, prevent from skidding by the frictional force between gear and power transmission shaft, but after long-time use, be easy to cause gear inwall and transmission shaft friction power to reduce, useful life is low, and the common power transmission shaft production cost with alignment pin is very high; Common travelling gear does not have protective device, is easy to cause wearing and tearing even to produce danger.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the problem of above-mentioned existence, provide a kind of transmission device for micro-machine, solve common micro-machine transmission device low useful life, production cost is high and there is no a problem of device for protecting gear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transmission device for micro-machine, comprise electric motor protecting box and and lid, lid center offers the through hole corresponding with motor transmission shaft, lid is enclosed within on power transmission shaft and is threaded with electric motor protecting box by through hole, on power transmission shaft sidewall, offer circular location notch, power transmission shaft top cover has the serrate travelling gear of sidewall interlude tool, travelling gear top has the circular protective sleeve for the protection of sawtooth, the nearly lower end of travelling gear sidewall offers the location hole corresponding with location notch, in location hole, insert alignment pin and the clamping of location notch phase.
Protective sleeve diameter is greater than travelling gear and has serrated face maximum gauge.
Very close to each other between alignment pin and location hole.
The invention has the beneficial effects as follows to there is gear protective sleeve and alignment pin on the transmission device for micro-machine of the present invention, greatly the non-skid property of lifting gear and the useful life of gear.
