Abstract
The utility model discloses a speed reduction box which comprises an active shaft and an inactive shaft, wherein the active shaft is provided with an active wheel, the inactive shaft is provided with an inactive wheel, the active and inactive wheels are linked, the active wheel has worm surface tooth structure, and the tooth face of the active wheel is connected with outer space via a worm rod. The speed reduction box has compact structure, small volume, stable gear operation in use, low noise, low abrasion and long service life.
Description
Technical field
The utility model relates to a kind of speed reducer.
Background technique
Speed reducer all can be used usually in the motor application field, can reach to slow down with it to increase the function of square, thereby improve roadability.The size of speed reducer is generally all decided with motor, but internal structure adopt the planetary gear train structures shape volume of speed reducer bigger, limited to its using scope; Noise is big when running up simultaneously, and gear wear is fast, and working life is short.
The model utility content
Problem to be solved in the utility model provides a kind of speed reducer, and internal structure is compact to design, low noise during work.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: this speed reducer box house is provided with driving shaft and driven shaft, described driving shaft is provided with driving wheel, described driven shaft is provided with follower, described driving wheel and follower interlock, described driving wheel is a snail face toothing, and the flank of tooth of described driving wheel is connected with outside by worm screw.
The utility model adopts technique scheme, compact structure, and the speed reducer volume reduces, and gear operation is steady during work, and noise is low, and wear extent reduces, and has prolonged working life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the general assembly drawing of a kind of speed reducer of the utility model.
Embodiment
As shown in Figure 1, speed reducer casing 1 inside is provided with driving shaft 2 and driven shaft 3, is provided with driving wheel 4 on driving shaft 2, on driven shaft 3, be provided with follower 5, driving wheel 4 and follower 5 interlocks, driving wheel 4 is a snail face toothing, the flank of tooth of driving wheel 4 is connected with outside by worm screw 6.After worm screw 6 was by driven by motor, driving wheel 4 just and then rotated, and then drove follower 5 and rotate, at last by driven shaft 3 outputs.
