Abstract
The utility model relates to a reducer, in particular to the reducer for a bucket wheel machine. The reducer for the bucket wheel machine comprises a machine body, a high speed shaft, a bearing seat, a large bevel gear, a secondary gear shaft, a three-level gear shaft, a drum-shaped gear shaft and a floating gear sleeve, wherein one side of the machine body is provided with the bearing seat, the high speed shaft is arranged on the bearing seat, the large bevel gear is arranged at one end of the high speed shaft, and the large bevel gear is connected with the high speed shaft in a meshing mode. When the reducer for the bucket wheel machine is operated, the high speed shaft transmits torsion to a sun wheel through the large bevel gear, the secondary gear shaft, the three-level gear shaft, the drum-shaped gear shaft and the floating gear sleeve, and finally the torsion is output by an internal spline of a planet carrier. The reducer for the bucket wheel machine solves the problems that an existing internal curve radial plunger speed type reducer is low in rotating speed, many in faults and difficult in maintenance and a reducer input shaft is prone to being broken off by the reducer with a planet carrier and bevel gear composite structure. By adopting a motor input pattern, the reducer for the bucket wheel machine has the advantages of being high in rotating speed and efficiency and particularly suitable for installation and use of the bucket wheel machine.
Description
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of bucket wheel machine speed reducer.
Background technique
Conventional bucket wheel machine has two kinds with speed reducer, that is: 1) directly adopt inner curve radial plunger type low speed high torque hydraulic motor to drive bucket wheel, because output shaft directly links to each other with bucket wheel, so rotating speed is lower.And oil hydraulic motor is in slow-speed of revolution district for a long time, and its efficient is not to be in the optimum value section, thereby fault increases maintenance difficult, and this type of oil hydraulic motor costliness.2) structure that adopts planet and bevel gear to make up, the means of fixation of speed reducer is that the bottom is fixed on the wheel axle by output hollow shaft, and the top of speed reducer is a fixedly loose collar, and speed reducer is floating type fixing.That is to say the deceleration body and drive to be relocation mechanism between the bogie frame, and the activity that floats is larger, and the base of motor is fixed on the driving bogie frame.Certain radial-play displacement occurs between motor shaft and the speed reducer input shaft during operation, and the radial load of generation finally causes the fracture of speed reducer input shaft, has the irrational defective of structural design.
Summary of the invention
The purpose of this utility model is: provide a kind of simple and reasonable, solved the radial load that produces because of the radial-play displacement between existing motor shaft and the speed reducer input shaft, cause the bucket wheel machine speed reducer of speed reducer input shaft breakage problem.
The technical solution of the utility model is:
A kind of bucket wheel machine speed reducer, it is by body, high speed shaft, bearing support, bevel gear wheel, the secondary gear axle, the tertiary gear axle, the crowned teeth axle, the tooth cover that floats consists of, it is characterized in that: body 5 one sides are equipped with bearing support 4 by fixing bolt, by tapered roller bearing A2 and selfaligning roller bearing A 3 high speed shaft 1 is installed on the bearing support 4, high speed shaft 1 one ends are provided with bevel gear wheel 6, bevel gear wheel 6 is connected with a joggle with high speed shaft 1, by tapered roller bearing B9 secondary gear axle 8 is installed on the body 5 of bevel gear wheel 6 belows, bevel gear wheel 6 is connected with secondary gear axle 8 by flat key 7, by tapered roller bearing C13 tertiary gear axle 12 is installed on the body 5 of secondary gear axle 8 one sides, tertiary gear axle 12 is fixed with secondary gear 10 by flat key B11, secondary gear 10 is connected with a joggle with secondary gear axle 8, by tapered roller bearing D17 crowned teeth axle 16 is installed on the body 5 of tertiary gear axle 12 1 sides, be fixed with tertiary gear 14 by flat key C15 on the crowned teeth axle 16, crowned teeth axle 16 is connected with a joggle by tertiary gear 14 and tertiary gear axle 12, be installed with planet carrier 20 by the selfaligning roller bearing B22 on deep groove ball bearing 21 and the rear cover 23 on the body 5 of crowned teeth axle 16 tops, sun gear 19 1 sides in the planet carrier 20 are fixedly mounted with planet wheel 27 by roller bearing 28, and sun gear 19 lower ends are connected with crowned teeth axle 16 by the tooth cover 18 of floating; Sun gear 19 upper ends and planet wheel 27 outer gearings, planet wheel 27 and internal gear 24 interior engagements.
The utility model has the advantage of
This bucket wheel machine is fixed on the motor support base by body with speed reducer, speed reducer and motor support base have a style of one's own, during work, high speed shaft transfers torque on the secondary gear axle by bevel gear wheel, then transfer torque to the tertiary gear axle by secondary gear, transfer torque to sun gear by tertiary gear, crowned teeth axle 16 and unsteady tooth cover 18 again, by the internal spline of planet carrier moment of torsion is exported at last.Solved existing inner curve radial plunger type speed reducer because output shaft directly links to each other with bucket wheel, so rotating speed is lower, its efficient is not to be in the optimum value section, thereby fault increases, maintenance difficult, and between the motor shaft of planet and bevel gear combination structure speed reducer and the speed reducer input shaft certain radial-play displacement occurs easily, the radial load of its generation, the problem that very easily causes the fracture of speed reducer input shaft, this bucket wheel machine adopts the mode of motor input with the speed reducer structure advantages of simple, has the rotating speed height, the characteristics that efficient is high.Being specially adapted to bucket wheel machine installs and uses.
