Abstract
The utility model relates to a speed change mechanism, particularly a stepless cycloidal combined multi-speed-ratio large torsional moment material-saving speed changer which is suitable for being used on automatic production lines and various mechanical adjusting and testing devices of various industries. The utility model solves the structural problem that the advantages of a stepless speed changer and the advantages of a cycloidal pin wheel speed reducer are combined. The utility model is characterized in that the structure of the stepless speed changer is connected with the structure of the cycloidal pin wheel speed reducer with a middle connecting disk; one side is connected with a box body of the stepless speed changer, and the other side is connected with a pin tooth casing on the cycloidal pin wheel speed reducer, which forms the stepless cycloidal combined multi-speed-ratio large torsional moment material-saving speed changer. Material can be economized by more than 30%, the volume is reduced by more than 40%, and the utility model is widely suitable for being used on automatic production lines of chemical industry, textile industry, beverage industry, glass industry, electronic instrument industry, etc.
Description
The utility model relates to gear, particularly is fit to the stepless cycloid combination multiple gear ratios high pulling torque material-saving variable-speed motor on every profession and trade automatic production line and the various mechanical commissioning device.
In gear, cycloidal-pin wheel retarder and stepless speed variator were arranged generally in the past.The cycloidal-pin wheel retarder mainly contains compositions such as input shaft, output shaft, end cap, bonnet, pin wheel housing, cycloid wheel, eccentric bushing and pin sleeve, pin gear sleeve, spacer ring, gear pin; Stepless speed variator mainly comprises driving shaft, end cap, casing, belleville spring, platen, the planet compositions such as examining wheel, pivoted arm and arrangements for speed regulation that rubs.Both respectively have advantage.Cycloidal-pin wheel retarder single-stage speed ratio just can reach 1: 87, and output torque is big, but slewing range is restricted; Stepless speed variator then slewing range is big, and the output speed ratio can change arbitrarily between 1: 45 to 1: 7.25.The combination of therefore original employing stepless speed variator and cycloidal-pin wheel retarder is that two independent equipment carry out the straight connection type combination, rather than entire combination, so waste material, and volume is big, is restricted on supporting adaptability.
The purpose of this utility model provides a kind of volume can dwindle 40%, and material economy reaches the stepless cycloid combination multiple gear ratios high pulling torque material-saving variable-speed motor more than 30%.
The technical solution of the utility model be complete machine half be the stepless speed variator structure, comprise input shaft (1), end cap (2), casing (3), belleville spring (4), platen (5), epicyclic friction gear (6), platen (7), pivoted arm (8); Second half is the cycloidal-pin wheel retarder, comprise pin wheel housing (10), cycloid wheel (11), eccentric bushing (12), bonnet (13), output shaft (14), comprise pin sleeve (15), pin gear sleeve (16), spacer ring (17), gear pin (18) on the cycloid wheel (11), cycloid wheel (11) is in transmission connection by bearing pin (19) and output shaft (14).Land (9) is connected in the middle of adopting between this 2 part-structure.Concrete Placement is that middle land (9) is fastenedly connected with casing (3) on one side, and is connected with input shaft (1) inserting end bearing; Another side and pin wheel housing (10) are fastenedly connected, and input shaft (1) inserting end and eccentric bushing (12) are in transmission connection, and constitute integral body of the present utility model.
Said cycloid wheel (11) is 1 and is installed on the eccentric bushing (12);
Said cycloid wheel (11) is two and is installed on the eccentric bushing (12).
The utility model has the advantages that the advantage multiple gear ratios high pulling torque slewing range of stepless speed variator and cycloidal-pin wheel retarder is combined greatly, and the volume after the combination is dwindled greatly that can dwindle 40%, material economy is more than 30%.
Further specify embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural drawing of the present utility model.
With reference to Fig. 1, the utility model left side one side of something has input shaft (1) to be connected with electric motor drive, and end cap (2), casing (3), belleville spring (4), platen (5), epicyclic friction gear (6), platen (7), pivoted arm (8) belong to the coaxial planetary friction formula of pivoted arm stepless speed variator structure; Right one side of something has pin wheel housing (10), cycloid wheel (11), eccentric bushing (12), bonnet (13), output shaft (14), find out from diagram, comprise pin sleeve (15), pin gear sleeve (16), spacer ring (17), gear pin (18) on the cycloid wheel (11), cycloid wheel (11) is in transmission connection by bearing pin (19) and output shaft (14), belongs to the cycloidal-pin wheel reducer structure.Inventive point of the present utility model is to be connected with middle land (9) between stepless speed variator structure and the cycloidal-pin wheel reducer structure, constitutes the overall structure of stepless cycloid combination multiple gear ratios high pulling torque material-saving variable-speed motor.The concrete Placement of middle land (9) is to be fastenedly connected with casing (3) on one side, and is connected with input shaft (1) inserting end bearing; Another side and pin wheel housing (10) are fastenedly connected, and input shaft (1) inserting end and eccentric bushing (12) are in transmission connection.
The utility model had both had the advantage of the coaxial planetary friction formula of pivoted arm buncher, i.e. compact conformation, Constant output characteristic is good, and bearing capacity is big, and transmission stabilization efficiency height also has high strength, slewing range big, also Arrangements for speed regulation can be installed, adjusting speed accuracy height, stable performance; The advantage that has again planet-cycloid reducer, Namely at a high speed than reaching 1: 87, moment of torsion is big, and efficient is up to more than 90%, and the smooth running noise is low, uses reliable Life-span is long. Extensively be used in chemical industry and chemical fiber, textile printing and dyeing, beverage/food, glass ceramics, light industry and machinery, The every profession and trade automatic assembly lines such as electronic instrument, pharmacy process hides and metallurgical mine, lifting transportation, lathe boiler, On the various mechanical commissioning device of the industrial departments such as rubber plastic. One in this machine just can replace original 2, Reach more than 30% through the combination economical with materials, and greatly dwindle original 2 volume and reach more than 40%.
