Abstract
A slip type high-multiple speed reducer consists of four parts of a wheel train mechanism 14, a reduction box body 15, a reduction box cover 16 and an electric motor 17. The electric motor 17 directly drives an input shaft 8 of the speed reducer; a rear input gear 1 and a front input gear 4 are installed on the input shaft 8 fixedly; the rear input gear 1 drives an intermediate gear 2 and then drives a ring gear 3; and the front input gear 4 drives a large intermediate gear 5, and drives an output gear 7 and an output shaft 9 to rotate through a small intermediate gear 6 coaxial with the large intermediate gear 5. Therefore, the rear input gear and the front input gear simultaneously drive the wheel train mechanism. Due to the difference of gear numbers, the slip is generated, which causes the output shafts of the speed reducer to obtain required high multiple transmission ratio. The speed reducer has novel structure and small volume, and can obtain various transmission ratios ranging from dozens to tens of thousands on condition of only making little calculation and regulation on the number of gears while unchanging the internal structure and appearance size.
Description
Technical field
Field involved in the present invention is mechanically operated speed reducer industry.
Background technique
Speed reducer occupies an important position in mechanical industry, the speed reducer industry through long-term development the typing speed reducer of various models as cylindrical gear reducer, worm reduction gear, planet wheel speed reducer, cycloidal planetary gear speed reducer etc.But speed reducer boundary dimension was bigger when velocity ratio was big, perhaps needed to adopt double reduction or more multistage combination.
Technology contents
For a kind of novel structure is provided, gear range is big exactly in the present invention, the speed reducer that boundary dimension is little.
The technological scheme that realizes the foregoing invention purpose is: slip type high-multiple speed reducer is made up of four big parts such as gear mechanism, speed reducer casing, speed reducer case lid, motor.
Gear mechanism is by preceding input gear, intermediate gear, ring gear, back input gear, big intermediate gear, little intermediate gear, output gear, input shaft, output shaft, long jack shaft, front baffle board, afterwards plate washer and relevant bearing washer etc. are assembled into integral body.
There is a bearing pilot hole at speed reducer casing center, and the output shaft of gear mechanism and bearing just are contained in the hole, and casing one end is to install to use adpting flange, the other end is installed the speed reducer case lid, be base below, slip type high-multiple speed reducer both can vertically be installed, and also can horizontally install.
There is a bearing pilot hole at speed reducer case lid center, the input shaft of gear mechanism and bearing just are contained in the hole, bearing pilot hole both sides two axis holes that are being symmetrically distributed, the brachymedial countershaft is packed in the axis hole, intermediate gear is sleeved on the brachymedial countershaft, speed reducer case lid one side links to each other with the speed reducer casing, and another side is installed motor.
The output sleeve of motor is contained in the axis hole of input shaft of gear mechanism, and motor is fastened on the speed reducer case lid.
Fixed installation back input gear and preceding input gear on the input shaft, back input gear driven intermediate gear, drive ring gear again, the big intermediate gear of preceding input gear driven, and by little intermediate gear drive output gear, the output shaft rotation coaxial with big intermediate gear.Back input gear and preceding input gear drive gear mechanism simultaneously, because the number of teeth is poor, have just produced slip, make output shaft obtain required high power velocity ratio.
In order to make stable drive and to improve driving torque, the intermediate gear symmetry of slip type high-multiple speed reducer is installed two, and big intermediate gear, little intermediate gear on circumference uniform four have respectively been installed 14 gears altogether in speed reducer.
The invention has the advantages that: novel structure, volume is little, on same speed reducer, can not change boundary dimension and internal structure, and only need when beginning to design, the number of teeth of gear to be done small calculating change, just can obtain various velocity ratios from tens to several ten thousand.

Among the figure: 1. back input gear, 2. intermediate gear, 3. ring gear, 4. before input gear, 5. big intermediate gear, 6. little intermediate gear, 7. output gear, 8. input shaft, 9. plate washers, 13. brachymedial countershafts, 14. gear mechanisms, 15. speed reducer casings, 16. speed reducer case lids, 17. motor behind output shaft 10. long jack shafts, 11. front baffle boards, 12..
Embodiment
As shown in the figure, slip type high-multiple speed reducer is made up of four big parts such as gear mechanism 14, speed reducer casing 15, speed reducer case lid 16, motor 17.
There is a bearing pilot hole at speed reducer casing 15 centers, and the output shaft 9 of gear mechanism and bearing just are contained in the hole, and casing one end is a mounting flange, and the other end is installed the speed reducer case lid, is mounting base below.Gear mechanism 14 is assembled into parts except that intermediate gear 2, integral installation is in the speed reducer casing.
There is a bearing pilot hole at speed reducer case lid 16 centers, the input shaft 8 and the bearing of gear mechanism just are contained in the hole, bearing pilot hole both sides two axis holes that are being symmetrically distributed, brachymedial countershaft 13 is packed in the axis hole, intermediate gear 2 is sleeved on the brachymedial countershaft 13, speed reducer case lid one side links to each other with the speed reducer casing, and another side is installed motor.
The output sleeve of motor 17 is contained in the axis hole of input shaft 8 of gear mechanism, and motor is fastened on the speed reducer case lid 16.
Motor directly drives the input shaft 8 of speed reducer, on input shaft, be installed with back input gear 1 and preceding input gear 4, back input gear 1 drives intermediate gear 2, drive ring gear 3 by intermediate gear 2 again, preceding input gear 4 drives big intermediate gear 5, and by drive output gears 7 with the coaxial little intermediate gear 6 of big intermediate gear 5, output shaft 9 rotates, back input gear and preceding input gear have just driven gear mechanism simultaneously like this, reason owing to number of teeth difference, just produced slip, made the output shaft of speed reducer obtain required high power velocity ratio.
Slip type high-multiple speed reducer is when calculating velocity ratio, only use seven gears, but in order to make stable drive and to improve driving torque, just intermediate gear 2 symmetries are installed two, big intermediate gear 5 and little intermediate gear 6 are distinguished uniform four on circumference, 14 gears have been installed in speed reducer altogether.
