Embodiment
Below in conjunction with accompanying drawing, the transmission system of the utility model speed reducer and structure are elaborated.
The power engine of railroad sleeper stud driver is generally motor or explosive motor, power engine start after, by output shaft by transmission of power to speed reducer, transmission of power is carried out work to the actuator of stud driver by speed reducer again.See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, speed reducer includes I spindle unit 1, II spindle unit 2, III spindle unit 3, intermediate shaft part 4, reversing gear 5, output shaft assembly 6, box part 7, I spindle unit 1 is fixedly connected with the output shaft 8 of power engine, be positioned at speed reducer, I shaftgear 9 of its I spindle unit 1 engages with the gearwheel 10 in the duplicate gear of II spindle unit 2, II spindle unit 2 is given by transmission of power, small gear 11 in duplicate gear engages with III shaftgear 12 of III spindle unit 3, III spindle unit 3 is given again by transmission of power, III shaftgear 12 is fixedly connected with the small coning gear shaft 13 of III spindle unit 3, small coning gear shaft 13 is driven to rotate together, top bevel gear wheel 14 and the bottom bevel gear wheel 14 of small coning gear shaft 13 and intermediate shaft part 4 engage simultaneously, by transmission of power to intermediate shaft part 4, two bevel gear wheels 14 respectively with land 15, copper sheathing 16 is fixedly connected with, be sleeved on jack shaft 17, the driving being subject to small coning gear shaft 13 rotates around jack shaft 17 shaft axis, the sense of rotation of two bevel gear wheels 14 is contrary, the commutation shift fork 18 of reversing gear 5 inserts in the annular groove of commutation clutch cover 19, commutation clutch cover 19 is by inner splined hole and the upper outside spline joint of jack shaft 17, for being slidably matched, commutation clutch cover 19 can be made to move up and down vertically by reversing gear 5, the jaw clutch pawl at upper and lower two ends can be combined with the jaw clutch pawl of upper and lower land 15 end respectively, power passes to the corresponding land up and down 15 connected by upper and lower bevel gear wheel 14 respectively, pass to commutation clutch cover 19 again, commutation clutch cover 19 by spline joint again by transmission of power to jack shaft 17, thus make jack shaft 17 synchronous rotary together with upper bevel gear wheel 14 or lower bevel gear wheel 14 respectively, when the clutch cover 19 that commutates is in not with the position that upper and lower land 15 is combined, upper and lower two bevel gear wheels 14 dally, rotating power no longer posteriorly transmission system transmission, jack shaft 17 is fixedly connected with intermediate gear 20, intermediate gear 20 is driven to rotate together or stop, intermediate gear 20 directly engages with the output gear 21 of the output shaft assembly 6 being arranged on both sides simultaneously, thus rotating power is passed to simultaneously the output gear 21 being arranged on both sides, again by the actuator of railroad sleeper stud driver, regulating mechanism, operating mechanisms etc. work accordingly.Except I spindle unit 1, II spindle unit 2, III spindle unit 3, intermediate shaft part 4, reversing gear 5, output shaft assembly 6 are arranged on box part 7.Compared with prior art, the intermediate shaft part at intermediate gear place, adopts bearings at both ends supporting, but not cantilever support, thus intermediate shaft part and aluminium alloy box stressed very reasonable, substantially improve the transmission meshing quality of gear simultaneously, efficiently solve the fragile and casing Leakage of relevant stressed part, the layout more compact and reasonable of whole transmission system, make speed reducer compacter small and exquisite, lightweight, fault is few, and thus the use and maintenance expense of user reduces greatly.
