For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of effectively reduces output shaft and worm gear friction, and the worm gear of the motor increased the service life.
For achieving the above object, the utility model provides following technological scheme: a kind of worm gear of motor, comprise diapire, be arranged on the external annulus of diapire periphery and be arranged on the internal ring wall of bottom wall central, the periphery of described external annulus arranges external tooth, axis hole is provided with in described internal ring wall, be provided with the internal tooth be arranged in parallel with the axial direction of axis hole in described internal ring wall, the inner side of described internal ring wall is provided with oil storage tank, and described oil storage tank is arranged in the form of a ring.
By adopting technique scheme, oil storage tank inner casing stores lubricant oil, and after motor long-term work, the lubricant oil in oil storage tank still can play lubrication to output shaft and worm gear, thus the friction decreased between output shaft and worm gear, and then extend the working life of motor.
The utility model is arranged further: described oil storage tank two side position is respectively arranged with groove, is embedded with O-ring seal in described groove.
By adopting technique scheme, the seal ring of oil storage tank both sides makes output shaft oil storage tank two corresponding to worm gear side position opposing seal, thus prevents the oil leakage in oil storage tank, further extends the working life of motor.
The utility model is arranged further: described internal ring wall one end is provided with at the inwardly protruded positioning boss of the radial direction of axis hole, and the groove of described oil storage tank side is arranged on described positioning boss.
By adopting technique scheme, the axial direction of positioning boss to output shaft plays positioning action, and the groove of oil storage tank side is arranged on described positioning boss, avoids the internal tooth position of internal ring wall, and make processing convenient, sealing effect is also better.
The utility model is arranged further: the described internal ring wall the other end is provided with the extension boss extended at the axial direction of axis hole, and the groove of described oil storage tank opposite side is arranged on the inwall of described extension boss.
By adopting technique scheme, avoid the internal tooth position of internal ring wall, make processing convenient, sealing effect is also better.
The utility model is arranged further: the stiffening rib radially arranged described diapire being provided with some quantity, and described diapire is also provided with the through hole of some quantity.
By adopting technique scheme, stiffening rib improves the steadiness of worm gear, and through hole makes motor internal air more easily circulate, and prevents motor internal local superheating, and further extends the working life of motor.
The utility model is arranged further: the inner side of described external annulus is also provided with connection ring wall, and described external annulus is provided with connecting tendon with being connected between ring wall.
By adopting technique scheme, further increase the steadiness of worm gear.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model example structure figure;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Embodiment
See accompanying drawing 1 to accompanying drawing 3, the worm gear of motor disclosed in the utility model, comprise diapire 1, be arranged on the external annulus 2 of diapire 1 periphery and be arranged on the internal ring wall 3 at diapire 1 center, the periphery of described external annulus 2 arranges external tooth 201, axis hole 301 is provided with in described internal ring wall 3, be provided with the internal tooth 302 be arranged in parallel with the axial direction of axis hole 301 in described internal ring wall 3, the inner side of described internal ring wall 3 is provided with oil storage tank 303, and described oil storage tank 303 is arranged in the form of a ring.By adopting technique scheme, oil storage tank 303 inner casing stores lubricant oil, and after motor long-term work, the lubricant oil in oil storage tank 303 still can play lubrication to output shaft and worm gear, thus the friction decreased between output shaft and worm gear, and then extend the working life of motor.
The utility model is arranged further: described oil storage tank 303 liang of side positions are respectively arranged with groove 304, are embedded with O-ring seal 4 in described groove 304.By adopting technique scheme, the O-ring seal 4 of oil storage tank 303 both sides makes output shaft oil storage tank corresponding to worm gear 303 liang of side position opposing seal, thus prevents the oil leakage in oil storage tank 303, further extends the working life of motor.
The utility model is arranged further: described internal ring wall 3 one end is provided with at the inwardly protruded positioning boss 305 of the radial direction of axis hole 301, and the groove 304 of described oil storage tank 303 side is arranged on described positioning boss 305.By adopting technique scheme, the axial direction of positioning boss 305 pairs of output shafts plays positioning action, and the groove 304 of oil storage tank 303 side is arranged on described positioning boss 305, avoids internal tooth 302 position of internal ring wall 3, make processing convenient, sealing effect is also better.
