Description
Technical field
The utility model relates to a kind of motor output reduction gearing mechanism, in particular, relates in particular to a kind of straight pin of spaced set that utilizes and replaces the motor of internal tooth to export reduction gearing mechanism.
Background technique
The output of motor is behind the gear or gear train deceleration that are meshed, and the form output that is meshed with external tooth through internal tooth again is a kind of power way of output comparatively commonly used.In the process of processing and fabricating,, make that the cost of whole transferring structure is higher because internal tooth is difficult for processing; And in case in toothed ring gear be damaged also easy-maintaining not.
Summary of the invention
The utility model provides a kind of straight pin of spaced set that utilizes to replace the motor of internal tooth to export reduction gearing mechanism in order to overcome the shortcoming of above-mentioned technical problem.
The motor output reduction gearing mechanism of the utility model comprises driving gear, type sprocket-type gear and rotates the outer ring that said driving gear is fixedly set on the output shaft of motor; Its specialization is: driving gear is connected with a type sprocket-type gear transmission through at least one pair of gear train that is meshed; The edge of said type sprocket-type gear evenly offers a plurality of breach, rotates on the outer ring and evenly is provided with a plurality of straight pins that match with breach, and the camber line between the camber line distance between adjacent two breach and adjacent two straight pins is apart from equating.
Driving gear is fixed on the output shaft, and motor rotates thereby order about driving gear through the driving to output shaft; Driving gear is realized the driving to class sprocket-type gear through gear train.Because type sprocket-type gear edge position spaced set is jagged, rotates the outer ring equal intervals and is provided with the straight pin that matches with breach; Like this, in class sprocket-type gear rotating process, will order about and rotate the outer ring rotation.This just is equivalent to utilize cooperating of breach and straight pin, has substituted the engagement of external tooth and grinding tooth; The fit form of breach and straight pin can guarantee good transmission, also can avoid processing the loaded down with trivial details of internal tooth, simplifies the structure, and has reduced cost.
The motor output reduction gearing mechanism of the utility model, said gear train comprises first gear, first small gear, second largest gear, second small gear and third pinion; The first gear and first small gear are fixed on first stationary axle, and the second largest gear and second small gear are fixed on second stationary axle, and third pinion is fixed on the 3rd stationary axle with a type sprocket-type gear.The form that adopts a plurality of gears to be meshed helps the setting of velocity ratio.
The motor output reduction gearing mechanism of the utility model, said driving gear is meshed with first gear, and first small gear is meshed with second largest gear, and second small gear is meshed with third pinion.The form that adopts gear to be meshed with gear helps multiple velocity ratio and sets.
The motor of the utility model output reduction gearing mechanism comprises two fixed plates that laterally arrange, and said first stationary axle, second stationary axle and the 3rd stationary axle rotational fixation are on two fixed plates.In the process of operation, gear only need rotate, and should keep relatively-stationary state, can realize effectively spacing to stationary axle through fixed plate.
The motor output reduction gearing mechanism of the utility model, the rotating speed of said type of sprocket-type gear and the rotating speed ratio of driving gear are less than 1.The velocity ratio of only guaranteed class sprocket-type gear and driving gear just can be realized the reduction of speed effect less than 1.
The beneficial effect of the utility model is: the motor output reduction gearing mechanism of the utility model; (1) through breach and matching of the straight pin type of belt drive that is meshed with external tooth of incompatible replacement internal tooth; Both guaranteed carrying out smoothly of transmission of power, the drawback of also having avoided the processing internal tooth to bring; (2) match through a plurality of gear trains, realized gearing down effectively.The driving mechanism of the utility model effectively reduces the difficulty of processing of internal tooth, and reduces the noise between gear.
Description of drawings
