Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of drive mechanism of towing machine retarder, utilizes this drive mechanism to reduce the loss rate that transmission is transmitted.
The purpose of this utility model can realize by following technical proposal: a kind of drive mechanism of towing machine retarder, be arranged on the casing, it comprises input shaft, transmission shaft and the output shaft that is axially fixed on the casing, it is characterized in that, described transmission shaft is arranged in a crossed manner with respect to input shaft, be connected by the bevel gear transmission device between the inner of described input shaft and the transmission shaft, be connected by gear drive between the inner of described output shaft and the transmission shaft.
The outer end of input shaft can link to each other with motor rotary shaft by coupler in the drive mechanism of this towing machine retarder, and the outer end of output shaft can link to each other with traction sheave.When the motor drives input shaft rotated, input shaft passed through bevel gear transmission device drive transmission shaft and rotates, and then transmission shaft drives the output shaft rotation by gear drive, output shaft drive traction sheave rotation thus.Bevel gear transmission device in this speed reduction gearing is used for intersecting interaxle transmission, is the mutual transmission between two cone gears; Its driving efficiency is generally 0.94～0.98, compared with prior art obviously has the high advantage of transmission efficiency.
In the drive mechanism of above-mentioned towing machine retarder, described bevel gear transmission device comprises the driving bevel gear portion that is positioned at input shaft the inner and the driven bevel pinion that is meshed with described driving bevel gear portion, and described driven bevel pinion is fixed on the transmission shaft.The end of input shaft has the umbrella tooth, and this structure has guaranteed the firmness of structure and the compactedness of structure.
In the drive mechanism of above-mentioned towing machine retarder, the profile of tooth in described driving bevel gear portion and the driven bevel pinion all is circular shape.Above-mentioned bevel gear screw bevel gear, screw bevel gear be a kind of can by stablize transmitting ratio steadily, the Transmission of low noise transmission; Its driving efficiency height, transmitting ratio is stable, and the circular arc overlap coefficient is big, the load-carrying capacity height, stable drive is smooth-going, reliable operation, compact conformation, advantage such as energy-conservation material-saving is saved the space, and wear-resistant, the life-span is long, and noise is little.In various mechanical drive, for the highest, concerning towing machine, can reduce power of electric motor widely with the driving efficiency of screw bevel gear thus, and then reduce unit consumption of energy, have very big economic benefit thus.The space minimum that the spiral bevel gear wheel drive mechanism needs when transmitting equal moment of torsion can reduce the volume of casing thus.
In the drive mechanism of above-mentioned towing machine retarder, described bevel gear transmission device comprises driving bevel gear that is fixed on input shaft inner end place and the driven bevel pinion that is meshed with described driving bevel gear, and described driven bevel pinion is fixed on the transmission shaft.Driving bevel gear separates production with input shaft in this structure, then have convenient for production, the advantage that productive costs is low; But also ease of assembly and maintenance simultaneously.
In the drive mechanism of above-mentioned towing machine retarder, the profile of tooth in described driving bevel gear and the driven bevel pinion all is circular shape.
In the drive mechanism of above-mentioned towing machine retarder, described gear drive comprises the active oblique gear portion that is positioned at transmission shaft one end and the driven helical wheel that is meshed with described active oblique gear portion, and described driven helical wheel is fixed on the place, inside of output shaft.
In the drive mechanism of above-mentioned towing machine retarder, described gear drive comprises active oblique gear that is fixed on transmission shaft one end and the driven helical wheel that is meshed with described active oblique gear, and described driven helical wheel is fixed on the inner end of output shaft.
Compared with prior art, the drive mechanism of this towing machine retarder has the advantage of compact conformation, driving efficiency height, long service life.
