Abstract
The invention relates to a dual-input standby speed reducer which comprises a box body and a speed reducer transmission mechanism, wherein the speed reducer transmission mechanism comprises two input shafts; the two input shafts are arranged coaxially and oppositely; two gears are arranged on an intermediate shaft of the speed reducer transmission mechanism and are in gear-meshing with the two input shafts respectively; each gear comprises a gear inner ring and a gear outer ring; the gear outer ring is in gear-meshing with the input shaft; the gear inner ring is penetrated on the intermediate shaft and is arranged in the gear outer ring; the inner wall of the gear outer ring is an inner ratchet wheel; a pawl is arranged on the outer wall of the gear inner ring and is matched with the inner ratchet wheel. When any motor works, one input shaft is in gear meshing with the a transmission gear outer ring, the inner ratchet wheel of the gear outer ring drives the gear inner ring to rotate through the pawl, the gear inner ring drives the intermediate shaft to perform speed-reducing transmission, the other motor is out of work, the intermediate shaft drives the other gear inner ring to rotate, the pawl on the gear inner ring slips on the inner ratchet wheel of the corresponding gear outer ring, no reverse torque is transmitted, and single motor of the gear reducer is subjected to normal speed-reducing transmission.
Description
Technical field
The present invention relates to a kind of speed reducer, is a kind of double input speed reducer for subsequent use specifically.
Background technique
On the transmission device that some high stables, Safety performance require, it is usually equipped with two motors and realizes a preparation and a use, is convenient to switch use, inspection operation.Arranging of two motors must need outfit two speed reducers, which improves user cost and adds usage space, being unfavorable for the compact Layout of each equipment room.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of structure simple, compact, take up room little, be convenient to compact Layout, by speed reducer for subsequent use for the double input of standby functions integration.
The technical solution used in the present invention is: a kind of double input speed reducer for subsequent use, comprise casing and reduction gearing mechanism, described reduction gearing mechanism comprises two input shafts, two coaxial opposing settings of input shaft, the jack shaft of reduction gearing mechanism is provided with two gears, two gears gears meshing two input shafts respectively, described gear comprises inner ring gear and gear outer ring, gear outer ring gears meshing input shaft, inner ring gear cross-under is on jack shaft, inner ring gear is arranged in gear outer ring, gear outer ring inwall is internal clickwork, inner ring gear outer wall is provided with ratchet, click-fit internal clickwork.
Adopt technique scheme, the invention has the beneficial effects as follows: two input shafts connect two motors respectively, during arbitrary machine operation, the input shaft that this motor of transmission connects, by the gear outer ring of this input shaft gear engagement driving gear, the internal clickwork of gear outer ring is through the transmission of ratchet driven gear inner ring, inner ring gear drives jack shaft gearing down, now another motor does not work, jack shaft drives the inner ring gear of another gear to rotate, ratchet on this inner ring gear skids on the internal clickwork of the gear outer ring of its correspondence, without reactive torque transmission, the normal gearing down of speed reducer list motor.When needing switch motor to work, stop arbitrary motor, switch another machine operation, the same single machine operation of speed reducer, a preparation and a use decelerating operation of dual-motor is integrated in a speed reducer, and its structure is simple, compact, takes up room little, is convenient to compact Layout.
