Abstract
The utility model provides a special construction decelerator, which is characterized in that the upper part in the box body is provided with a big gear two-way output shaft; the lower part of the box body is provided with a small gear shaft meshed with the big gear; the small gear shaft is provide with a big bevel gear; the box bodies on the two sides of the big bevel gear are respectively provided with an input small bevel gear shaft and a small bevel gear shaft that are meshed with the big bevel gear; the box body outside on the side of the input small bevel gear is provided with an electric motor with the electric motor connection plate. The electric motor output shaft is provided with a small input gear and the shaft end of the small input bevel gear is provided with an input gear that is meshed with the small input gear of the electric motor, thereby realizing the objective that a set of decelerator has two synchronous output shafts. The device has the advantages of small volume and low cost, as well as a compact structure and a high efficiency.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of building industry special reduction gear.
Background technique
Construction machinery equipment is different from other machinery, and it mainly is portable engineering machinery, so should cube little to speed reducer, the step output function of seeking common ground again so just can make the synchronous operations simultaneously of two equipment.Known speed reducer is the universal product mostly, does not possess synchronous output function.In order to realize synchronous output, adopt two speed reducers to install side by side at present, pitch wheel and idle wheel are installed on each speed reducer output shaft, thereby are reached the purpose that output shaft rotates synchronously.This structural volume is big, cost is high, is not suitable for construction machinery equipment.
Summary of the invention
The purpose of this utility model is to overcome the deficiency in the known technology and the building industry special reduction gear that a kind of compact structure is provided, has synchronous output function.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The building industry special reduction gear, comprise rectangular box, be installed in the output shafts that gearwheel is housed in the casing, be installed in the casing and gearwheel pinion in mesh axle, be installed in the casing outside and have the motor that motor connects dish, the gear drive that is installed in the input small gear on the motor output shaft and rotates with the drive case internal pinionmw axle of importing pinion, it is characterized in that: described gear drive is that a bevel gear wheel is installed on pinion shaft, the input small coning gear shaft and the synchronous small coning gear shaft that are meshed with bevel gear wheel are installed respectively on the casing of bevel gear wheel both sides, and the axle head of input small coning gear shaft is equipped with the input gear that is meshed with motor input small gear.
Advantage and the good effect that the utlity model has are: because a bevel gear wheel is installed on the pinion shaft in casing, on two side box bodies, install with the input small coning gear shaft of bevel gear wheel engagement and small coning gear shaft synchronously, the input gear that is meshed with motor input small gear is installed at input small coning gear shaft axle head, transmission by large and small bevel gear realizes that the diaxon of a speed reducer exports synchronously in casing like this, reduce volume greatly, reduce cost, model utility also has compact structure, advantage that efficient is high.
