Abstract
The utility model relates to a stepless cycloidal planet speed reducer which belongs to a class of a cycloidal planet speed reducer. The utility model is characterized in that a speed variator is additionally arranged between a motor and a cycloidal planet speed reducer, and the section of the speed reduction of a cycloidal planet adopts the method that an outer cycloidal planet gear and a needle tooth ring which are connected into integration are driven by an eccentric sleeve which is rigidly connected with an input shaft. Furthermore, a fixing needle tooth ring is meshed with the outer cycloidal planet gear, the outer cycloidal planet gear is meshed with a planet needle tooth ring and fixedly connected with an output shaft to be output, the speed reduction ratio is 5-1700, and the speed variation range is 1.2-3. The utility model has the advantages of compact structure, small size and light weight.
Description
The utility model belongs to the speed reducer class.
Along with the raising of all trades and professions automatization level,, increasing need to propose that reduction speed ratio is very little can change the speed reducer of rotating speed under non-stop-machine situation again in departments such as printing and dyeing, food, weaving, chemical industry, light industry, pharmacy.And at present, the cycloidal-pin wheel planetary speed reducer of plant produced, one-level reduction speed ratio minimum is 9, be 87 to the maximum, greater than 87 speed reducer, adopt plural serial stage to slow down more reduction speed ratio, its type of belt drive is a K-H-V mechanism, promptly adopts the engagement of external cycloidal teeth-shaped and pin tooth, the output of pin-type load W mechanism.The speed reducer of this type does not reach the speed ratio less than 9, the while complex structure, and the requirement on machining accuracy height, the processing technology complexity, volume is big, and transmission performance is poor.
It is bigger that the purpose of this utility model provides a kind of reduction range, the infinite variable speed small-power stepless speed changer of energy, and velocity ratio is 5-1700, and can be implemented under the non-stop-machine situation, changes the purpose of rotating speed.Slewing range is 1.2-3
The purpose of this utility model is achieved in that 1, increases speed change gear between cycloid in planet speed reducer and motor.2, the eccentric bushing that is connected with speed reducer input shaft rigidity drives epicycloid planet wheel and the pin gear ring that connects as one, and the locking pin gear ring is meshed with the epicycloid planet wheel, and epicycloidal gear and planet pin gear ring mesh, and exports with output shaft fixed connection.
Description of drawings:
Fig. 1, a kind of embodiment's of the present utility model main sectional view.
Accompanying drawings detailed structure of the present utility model.
Speed change gear of the present utility model adopts the ball planet stepless speed changes devices, motor shaft links to each other with key with tapered sleeve axle (3), steel ball (4) is as planet wheel, along by tapered sleeve (20) and (21) two raceway lift-over that the conical surface is formed, retainer (5) is connected with key with input shaft (7), rack tube (1) is connected as a single entity by bearing with tapered sleeve axle (3), the central shaft of transmitting gear (2) is fixed on the casing and with rack tube (1) and is meshed, swing pinion (2) just can make the tapered sleeve axle move axially, and realizes the purpose of speed change with the radial position that changes steel ball.Spring (19) is pressed in the right side of tapered sleeve (20); The eccentric bushing (18) that is connected with input shaft (7) rigidity drives epicycloid planet wheel (10) and the planet pin gear ring (14) that connects as one, locking pin gear ring (11) is meshed with epicycloid planet wheel (10), the engagement of epicycloidal gear (15) and planet pin gear ring (14), and balancing weight (9) is arranged with output shaft (16) output eccentric bushing (18) one ends that are connected.
Speed change of the present utility model and deceleration two-part and are integral with the motor direct connection all on same axis.For this reason, volume ratio has speed reducer now, under power situation, and volume-diminished 1/3rd.
The utility model compact structure volume is little, and is in light weight, and manufacturing is simple.Because its reduction speed ratio scope is big, and again can speed governing,, can be extensive use of at industrial departments such as printing and dyeing, food, weaving, chemical industry, light industry, pharmacy for this reason.
Claims (3)
1, a kind of cycloid in planet speed reducer, it comprises housing, input, output shaft is characterized in that, (1) has increased speed change gear between cycloid in planet speed reducer and motor; (2) eccentric bushing that is connected with the input shaft rigidity drives epicycloid planet wheel and the planet pin gear ring that connects as one, and the locking pin gear ring is meshed with the epicycloid planet wheel, and epicycloidal gear and planet pin gear ring mesh and export with output shaft fixed connection.
2, cycloid in planet speed reducer as claimed in claim 1 is characterized in that speed change gear is the ball planet stepless change.
3, cycloid in planet speed reducer as claimed in claim 1 is characterized in that speed change and slows down all on same axis, and is integral with the motor direct connection.
