The specific embodiment
Referring to Fig. 1 Fig. 2, Fig. 3, Fig. 4
How how be used for JSDB series double speed mainly is made up of with hoist redution gear 5, motor gear 6, planet stent 7, big internal gear 8, key 9, brake wheel 10, articulation hole bolt 11, small ring gear 12, plunging joint gear 13, key 14, angular wheel shaft 15, brake shoes 16, braking mechanism 17, brake handgrip 18, left cover 19, right cover plate 20, outer cover plate 21 etc. electrical motor 1, epicyclic transmission mechanism 2, service braking mechanism 3, clutch and brake mechanism 4, double speed with the soft start mechanism of winch.
Be used for JSDB series double speed and use the soft start mechanism of winch more; Include the motor gear 6 that is fixedly set on the motor output shaft; Shift sleeve is equipped with planet stent 7 on the motor gear 6; The wheel hub of planet stent 7 is set with big internal gear 8 outward, and said motor gear 6, planet stent 7 and big internal gear 8 constitute epicyclic transmission mechanisms 2; The output shaft external fixation of planet stent 7 is set with brake wheel 10, is fixedly connected with small ring gear 12 on the outer face of brake wheel 10, and shift sleeve is equipped with plunging joint gear 13 in the small ring gear 12, and plunging joint gear 13 internal fixation are set with angular wheel shaft 15; Also include the service braking mechanism 3 of control big internal gear 8 and the clutch and brake mechanism 4 of control brake wheel 10.
The both sides of big internal gear 8 are installed with left and right cover plate 19,20 respectively. Part 19,20 is supported on respectively on 7 of motor flange and the planet stents through the antifriction-bearing box in covering.The right side of said brake wheel 10 is installed with the outer cover plate 21 that is sleeved on outside the plunging joint gear 13.
