Abstract
Provided is a decelerator for a construction elevator, comprising an input gear shaft, a transmission shaft, a transmission shaft bull gear, a transmission shaft pinion, an output shaft, an output shaft gear and a housing. The decelerator for a construction elevator is characterized in that the transmission shaft bull gear and the transmission shaft pinion are fixedly connected to the transmission shaft; the output shaft gear is fixedly connected to the output shaft; the input gear shaft is connected to the output end of the driving motor to transmit the torque to the input gear shaft; the gear of the input gear shaft is engaged with the transmission shaft bull gear to transmit the torque to the transmission shaft; the transmission shaft pinion is engaged with the output shaft gear to transmit the torque to the output shaft; the output shaft transmits the torque to the elevator; the transmission shaft pinion and the output shaft gear both adopt a spiral bevel gear. The decelerator for a construction elevator is advantageous in that the transmission shaft pinion and the output shaft gear both adopt the spiral bevel gear, and thereby vertical transmission of the torque can be realized, and the size of the integral decelerator can be reduced; bearing capability is high, and work stationary and tolerance is high.
Description
Technical field
The application relates to a kind of building hoist retarder, particularly relates to a kind of building hoist retarder with simple and reliable mechanism and higher transmission efficiency.
Background technique
Retarder is the independent gear between prime mover and working machine, is used for reducing rotating speed and increases torque.Traditional retarder generally adopts the worm and gear structure, and transmission efficiency is low, can not satisfy the requirement of big lifting force in the work progress.
China utility model patent CN201925414U discloses a kind of lifter reducer that adopts secondary gear to slow down, and driving efficient is higher, installation is comparatively convenient, but parallel structure is all adopted in the secondary gear deceleration, and the speed reducer size is bigger.
Summary of the invention
The application namely designs in view of problem in the past, and its purpose is to provide a kind of retarder for building hoist, and this retarder has that transmission efficiency is higher, compact structure reliable, characteristic of simple is installed.
For achieving the above object, the application is by the following technical solutions: a kind of building hoist retarder, it comprises the input gear shaft, transmission shaft, the transmission shaft gearwheel, shaft pinion, output shaft, output shaft gear and housing, it is characterized in that, described transmission shaft gearwheel and described shaft pinion are fixed on described transmission shaft, described output shaft gear is fixed on described output shaft, described input gear shaft is connected to transfer torque to described input gear shaft with the output terminal of drive motor, gear on the described input gear shaft and the engagement of described transmission shaft gearwheel are to be delivered to described transmission shaft with described moment of torsion, described shaft pinion and the engagement of described output shaft gear are to be delivered to described output shaft with described moment of torsion, described output shaft outputs to described lift with described moment of torsion, described shaft pinion, described output shaft gear all adopts spiral bevel gear.
As above-mentioned building hoist retarder, gear and transmission shaft gearwheel on the input gear shaft are helical gear.
With the building hoist of existing worm and gear structure retarder project, the application has the following advantages: this retarder adopts gear-driven form, therefore has higher transmission efficiency.The gear transmission structure reliability is installed more simply, does not adopt the copper turbine, has reduced abrasive wear, has improved oil leakage phenomenon, more environmental protection.Input shaft gear and transmission shaft gearwheel are helical gear, advantage such as have bearing capacity height, engagement contact ratio height, gear transmission is steady, noise is low, shaft pinion, output shaft gear adopt spiral bevel gear, realize the vertical transmission of moment of torsion, be conducive to reduce the retarder overall dimensions, also have simultaneously bearing capacity height, stable working, characteristics that tolerance is high.
Description of drawings
Fig. 1 is that expression is according to the structural representation of the application's retarder.
Embodiment
Below, the mode of execution to the application describes with reference to the accompanying drawings.
Fig. 1 is the structural representation that the expression building hoist is used retarder.Retarder comprises input gear shaft 1, transmission shaft 2, transmission shaft gearwheel 3, shaft pinion 4, output shaft 5, output shaft gear 6 and housing 7.Input gear shaft 1 links to each other with the drive motor output terminal, transmission shaft 2 is connected with transmission shaft gearwheel 3 usefulness splines, gear and transmission shaft gearwheel 3 on the input gear shaft 1 are meshing with each other, moment of torsion is delivered to transmission shaft 2 by input gear shaft 1, transmission shaft 2 is connected with shaft pinion 4 usefulness splines, output shaft 5 is connected with output shaft gear 6 usefulness splines, shaft pinion 4 is meshing with each other with output shaft gear 6 moment of torsion is delivered to output shaft 5 by transmission shaft 2, output shaft 5 is connected with working machine, moment of torsion is outputed to lift, shaft pinion 4, output shaft gear 6 all adopts spiral bevel gear, to realize the vertical transmission of described moment of torsion.
Gear and transmission shaft gearwheel 3 on the input gear shaft 1 are preferably helical gear.
Though the application adopts above-mentioned embodiment to be described, the application is not limited to above-mentioned mode of execution, and various changes and modifications all are within the application's the protection domain.
