As shown in fig. 1, the utility model provides a scraper conveyor speed reducer input shaft assembly, it sets up in the inside of speed reducer casing, including first end cover 10, second end cover 20, planet carrier 30, sun gear axle 40, planet wheel axle 50, ring gear 60 and swivel nut 70.
The first end cover 10 and the second end cover 20 are oppositely arranged and are fixedly connected with the speed reducer casing through a first bolt 11.
The planet carrier 30 is disposed in the first end cap 10 and is rotatably connected to the first end cap 10 by a first bearing 12. The inner ring of the first bearing 12 is fixedly connected with the planet carrier 30, and the outer ring of the first end cover 10 is fixedly connected. The planet carrier 30 is provided with a key slot for receiving power from the output shaft of the motor.
The sun gear shaft 40 is located between the first end cap 10 and the second end cap 20. A sun gear 41 is mounted to each of the first and second ends of the sun gear shaft 40.
A plurality of planetary shafts 50 are evenly distributed circumferentially outside the first end of the sun gear shaft 40. The first ends of the plurality of planetary shafts 50 are all fixedly connected with the first end cover 10. Each planet wheel shaft 50 is provided with at least one planet wheel 51, and the planet wheel 51 is engaged with the sun wheel 41 at the first end of the sun wheel shaft 40.
The ring gear 60 is fitted over the outside of the first end of the sun gear shaft 40. The outer side of the ring gear 60 is fixedly connected with the reducer casing, and the inner side is meshed with the planet gears 51.
The first end cap 10, the second end cap 20, the planet carrier 30 and the sun gear shaft 40 are all coaxially arranged.
The rotary sleeve 70 is provided at a second end of the sun gear shaft 40, and a gear 71 is attached to an outer peripheral surface thereof. The first end of the rotating sleeve 70 is rotatably connected to the second end cap 20 by a second bearing 72. The inner race of the second bearing 72 is fixedly connected to the rotating sleeve 70 and the outer race is fixedly connected to the second end cap 20. The inner side of the rotary sleeve 70 engages with the sun gear 41 at the second end of the sun gear shaft 40.
The sun wheel shaft 40, the sun wheel 41, the planet wheel shaft 50 and the planet wheel 51 together form a planetary gear structure. When the planet carrier 30 is driven by the motor to rotate, the planetary gear structure can reduce the rotation speed of the output shaft of the motor, so that the rotation speed of the gear 71 is reduced, and the purpose of reducing the speed is achieved.
The second bearing 72 and the planetary gear structure directly act to stabilize the position of the sun gear shaft 40, so that the position of the sun gear shaft 40 is stabilized, and the stability of the whole assembly is good.
In one embodiment, it further comprises a plurality of balls 52 circumferentially distributed between the planet wheel shaft 50 and the planet wheels 51. The balls 52 reduce friction between the pinion 71 and the pinion 71 shaft, so that the pinion 71 rotates more smoothly by the ring gear 60, thereby further improving the stability of the entire assembly.
In one embodiment, a first locating block 31 and a first nylon washer 53 are also included. The first locating block 31 is fixedly mounted on the planet carrier 30 and is coaxially arranged with the sun gear shaft 40, the first nylon gasket 53 is positioned between the first locating block 31 and the sun gear shaft 40, and two ends of the first nylon gasket 53 are respectively connected with the first locating block 31 and the sun gear shaft 40. The first nylon washer 53 connects the first positioning block 31 and the sun gear shaft 40 together, limits the offset of the axis line of the sun gear shaft 40, improves the coaxiality of the two, and further improves the stability of the whole assembly.
In one embodiment, a second locating block 21 and a second nylon washer 54 are also included. The second positioning block 21 is fixedly installed on the second end cap 20 and coaxially arranged with the sun gear shaft 40, the second nylon washer 54 is located between the second positioning block 21 and the sun gear shaft 40, and two ends of the second nylon washer 54 are respectively connected with the second positioning block 21 and the sun gear shaft 40. The second nylon washer 54 connects the second positioning block 21 and the sun gear shaft 40 together, so that the offset of the axis line of the sun gear shaft 40 is limited, the coaxiality of the two is improved, and the stability of the whole assembly is further improved.
In one embodiment, a connecting ring 80 is also included, disposed between ring gear 60 and gear 71. The connection ring 80 is sleeved outside the sun gear shaft 40 and connected with the second ends of the plurality of planetary gear shafts 50, and the connection ring 80 is rotatably connected with the reducer casing through a third bearing 81. When the planetary axle 50 is driven by the planet carrier 30 to rotate, the connection ring 80 can rotate together and support the second end of the planetary axle 50, so that the rotation of the planetary axle 50 is more stable.
In one embodiment, the reducer further includes a fourth bearing 90 disposed outside the second end of the rotating sleeve 70, an inner ring of the fourth bearing 90 is fixedly connected to the rotating sleeve 70, and an outer ring of the fourth bearing is fixedly connected to the reducer casing. The fourth bearing 90 acts directly on the second end of the rotary sleeve 70, thereby making the rotation of the rotary sleeve 70 and the gear 71 more stable. Thereby further improving the stability of the overall assembly.
In one embodiment, a seal sleeve 13 is disposed between the first end cap 10 and the planet carrier 30, and a felt oil seal 14 is disposed between the seal sleeve 13 and the planet carrier 30. Because the working environment of the coal industry is poor, more dust is often floated in the air, so the sealing sleeve 13 can prevent the dust in the air from entering the inside of the whole assembly, and the speed reducer is prevented from breaking down. The felt oil seal 14 can play a role in dust prevention and oil sealing, and lubricating oil leakage inside the whole assembly is avoided.
