Description
Technical field
The utility model relates to a kind of speed reducer, particularly a kind of track-type speed reducer that is used for.
Background technique
In the existing engineering machinery, a kind of track-type speed reducer that is used for of use mainly is made of oil hydraulic motor, hydraulic control device, retarder and break.Retarder in this machine contains frame, inner housing, one-level planetary wheeling mechanism, secondary planet wheel mechanism and input shaft, and on inner housing, one, two planetary wheeling mechanisms all are positioned at the inside of frame to frame by Bearing Installation.Because the frame of retarder is made into whole structure shape, just cumbersome when therefore the I and II planetary wheeling mechanism is installed to the inside of frame, when break down in inside, overhaul also very inconvenient equally.
The model utility content
The technical problems to be solved in the utility model provides a kind of track-type speed reducer that is used for, and it is convenient to install and maintenance.
For solving the problems of the technologies described above, the utility model is used for the track-type speed reducer, it contains oil hydraulic motor, hydraulic control device, retarder and break, retarder contains frame, inner housing, one-level planetary wheeling mechanism and secondary planet wheel mechanism, contain the one-level ring gear in the one-level planetary wheeling mechanism, contain the secondary ring gear in the secondary planet wheel mechanism, the frame of described retarder comprises right shell body, middle shell and left shell, described one-level ring gear is arranged in the right shell body, described secondary ring gear is arranged in the middle shell, described left shell by Bearing Installation on inner housing, right shell body, middle shell is arranged in order with left shell and is in the same place by bolt.
Because the frame of retarder is made of right shell body, middle shell and left shell three parts, and is arranged in order by bolt together, when break down in inside, only unload bolt and just can overhaul like this, therefore overhaul very convenient.Equally, because therefore frame is easy to the one-level ring gear is installed in the right shell body for dividing body structure, the secondary ring gear is installed in the middle shell, and is therefore easy for installation.

Accompanying drawing is a structural representation of the present utility model.
1. bolts in the accompanying drawing, 2. inner housing, 3. break, 4. motor casing, 5. output shaft, 6. hub splines, 7. input shaft, 8. secondary ring gear, 9. secondary planetary gear, 10. one-level ring gear, 11. primary planet pinions, 12. the primary planet pinion frame, 13. end caps, 14. one-level sun gears, 15. secondary sun gear, 16. secondary planetary gear framves, 17. sprocket wheels, 18. right shell body, 19. middle shells, 20. left shells.
Embodiment
In the accompanying drawing, the utility model is used for the track-type speed reducer and contains oil hydraulic motor, hydraulic control device, retarder and break 3.Retarder contains frame, inner housing 2, one-level planetary wheeling mechanism, secondary planet wheel mechanism and input shaft 7.The one-level planetary wheeling mechanism contains one-level ring gear 10, primary planet pinion 11, primary planet pinion frame 12 and one-level sun gear 14, and the secondary planet wheel mechanism contains secondary ring gear 8, secondary planetary gear 9, secondary planetary gear frame 16 and secondary sun gear 15.Hydraulic motor output shaft 5 is connected by hub splines 6 with input shaft of speed reducer 7, and hub splines 6 is arranged in inner housing 2.One-level sun gear 14 is fixedly mounted on the input shaft 7, and secondary sun gear 15 is sleeved on the input shaft 7.The frame of retarder comprises right shell body 18, middle shell 19 and left shell 20, and one-level ring gear 10 is arranged in the right shell body 18, and secondary ring gear 8 is arranged in the middle shell 19, left shell 20 by Bearing Installation on inner housing 2.Right shell body 18, middle shell 19 and left shell 20 are arranged in order and are fixed together by bolt 1.End cap 13 is arranged on the right shell body.Oil hydraulic motor and hydraulic control device are installed in the motor casing 4, and motor casing 4 is arranged on the end face of inner housing 2.Three primary planet pinions 11 are arranged on the primary planet pinion frame 12 by rotating shaft and bearing, the spline housing that primary planet pinion frame 12 central authorities are provided with is sleeved on the splined shaft that secondary sun gear 15 1 ends are provided with, three primary planet pinions 11 all with one-level ring gear 10 and 14 engagements of one-level sun gear.Three secondary planetary gears 9 are arranged on the secondary planetary gear frame 16 by rotating shaft and bearing, and three secondary planetary gears 9 all mesh with secondary ring gear 8 and secondary sun gear 15.Secondary planetary gear frame 16 is fixedly installed on the inner housing 2, and it also can make an overall structure with inner housing 2.The inner housing 2 of retarder is arranged on by bolt on the body of engineering machinery, and sprocket wheel 17 is fixed on the left shell 20 of retarder.Because the utility model is with the frame of the retarder of prior art, be made into the branch body structure of right shell body 18, middle shell 19 and left shell 20, and be arranged in order by bolt 1 and be fixed together, like this when break down in inside, only unload bolt 1 and just can overhaul, therefore overhaul very convenient.Equally, because therefore frame is easy to one-level ring gear 10 is installed in the right shell body 18 for dividing body structure, secondary ring gear 8 is installed in the middle shell 19, and is therefore easy for installation.During work, hydraulic motor output shaft 5 drives input shaft 7 by hub splines 6 rotates one-level sun gear 14, sun gear 14 drives primary planet pinion 11 and rotates, the rolling in one-level ring gear 10 that the rotation of primary planet pinion 11 forms, thereby make the spline housing on the primary planet pinion frame 12 drive secondary sun gear 15 rotations, secondary sun gear 15 drives secondary planetary gear 9 again and rotates, the rolling in secondary ring gear 8 that the rotation of secondary planetary gear 9 forms, be fixedly installed on because of secondary planetary gear frame 16 on the body of engineering machinery, finally make left shell 20 driving sprocket wheels 17 of retarder drive crawler travel.
