Abstract
The utility model discloses a gear reducer for a lifter, which comprises a box body and a cylindrical angular gear transmission mechanism arranged in the box body; the cylindrical angular gear transmission mechanism comprises an input shaft, a first gear arranged in the input shaft, a middle shaft, a second gear fixed on the middle shaft by a flat key, a third gear connected with the middle shaft in one body, an output shaft, a fourth gear fixed on the output shaft by the flat key and an output gear fixedly connected with the output shaft; the first gear is meshed with the second gear; the third gear is meshed with the fourth gear; and the box body close to the output shaft is provided with pulleys of an aligning ball bearing. The gear reducer for the lifter disclosed by the utility model has the advantages of large output torsion and high transmission efficiency.
Description
Technical field
The utility model relates to the special-purpose speed reducer of a kind of lift.
Background technique
Speed reducer is the transmission part between motor and working machine, is the required high pulling torque slow-speed of revolution of working machine through speed reducer with the little goes through torque conversion of high rotating speed of motor, and traditional speed reducer is realized this function through turbine and worm; Because the transmission efficiency of turbine and worm is low, heating value is big, can not adapt to load and require the earth equipment to use; Lift particularly, because it is frequent to go up and down, load is bigger in the construction; Therefore, can not adopt worm and gear to realize.
Summary of the invention
The purpose of the utility model is to provide a kind of lift that can solve foregoing problems to use gear reduction unit to the low problem of speed reducer transmission efficiency described in the background technique.
The technological scheme of goal of the invention that can realize the utility model is following:
A kind of lift is used gear reduction unit; It comprises casing and the slant gear transmission mechanism that is arranged in the casing; Slant gear transmission mechanism comprises input shaft, is arranged at first gear of input shaft, jack shaft, the output gear that is fixed in second gear on the jack shaft, the 3rd gear that is connected with the jack shaft one, output shaft, is fixed in the 4th gear on the output shaft and is fixedly connected with output shaft through flat key through flat key; First gear and second gear engagement; The 3rd gear and the 4th gear engagement, the other casing of output shaft is provided with the pulley of selfaligning ball bearing.
The input shaft of described one-level gear drive connects motor flange through the coupling with flat key.
The bearing of described output shaft adopts selfaligning roller bearing.
The lift of the utility model comes the rotating speed of output shaft is changed through slant gear transmission mechanism with gear reduction unit, and input end is connected motor flange with click through the coupling with flat key, and first gear is set on input shaft; First gear is a small gear, and second gear that drives on the jack shaft rotates, and second gear diameter is bigger; Through the transmission between first gear and second gear, rotating speed has reduced, and moment of torsion is improved; On jack shaft, be set with the 3rd gear, the 3rd gear also is a small gear, and the 4th gear is set on output shaft; The 4th gear is a gearwheel, through the 3rd gear and the 4th gear meshing, the output shaft rotating speed is reduced; Output torque gets a promotion, and through controlling the number of teeth of first gear, second gear, the 3rd gear and the 4th gear, regulates velocity ratio; Can regulate the output speed and the output torque of speed reducer according to actual needs, satisfy actual demand.
Description of drawings
Fig. 1 is the schematic representation of the utility model;
Among the figure, 1 is casing, and 2 is input shaft, and 3 is first gear, and 4 is jack shaft; 5 is second gear, and 6 is the 3rd gear, and 7 is output shaft, and 8 is the 4th gear, and 9 is output gear; 10 is selfaligning ball bearing, and 11 is coupling, and 12 is motor flange, and 13 is selfaligning roller bearing.
Embodiment
