Abstract
The utility model provides a hub reduction gear driven by an oil motor. The hub reduction gear consists of the oil motor (1), a sun gear (2), a planet gear (3), a gear ring (4), a planet gear carrier (5), a planet shaft (6), a wheel core (7), a front cover plate (8), a rear baffle (9), a 6826 deep groove ball bearing (10), an HK/20*26*25 needle bearing (11) and a sealing ring (12), wherein the output torque of the hub reduction gear is great and the total length is controlled within 230mm so that the requirement of a pesticide spraying machine on the total length of the hub reduction gear is met; the production assembling difficulty of a planet speed reduction device is reduced and the service life of the hub reduction gear is greatly prolonged; and furthermore, the construction cost is reduced and the hub reduction gear with excellent quality and reasonable price is supplied for a self-propelled pesticide spraying machine manufacturing enterprise.
Description
[technical field] the utility model is a kind of wheel reductor, is a kind of wheel reductor that drives with oil motor specifically.
[background technique] in recent years, along with the development of full-hydraulic self-propelled vehicle-mounted sprayer, increasing to the demand of wheel reductor, technical requirements is more and more higher.The domestic wheel reductor assembly long (350-380mm) with the oil motor driving of selling on market is now easily hindered seedling during walking; The wheel reductor assembly cost that drives with oil motor of import is too high, and the peasant holds and dares not accept; Too little with the direct driving torque of wheel motor, can not meet the demand that the vehicle-mounted sprayer normal operation is walked.The active demand of vast vehicle-mounted sprayer manufacturer can have a kind of both durable in use, no seedling injury again, the cheap wheel reductor that drives with oil motor.
For satisfying the active demand of vast vehicle-mounted sprayer manufacturer, the utility model provides a kind of wheel reductor that drives with oil motor [summary of the invention].
For solving its technical problem, the technical solution adopted in the utility model is: this wheel reductor comprises that oil motor, sun tooth, planet tooth, gear ring, planet braces, planet axis, core wheel, front shroud, backboard, 6826 deep groove ball bearings, HK/20*26*25 needle bearing, seal ring form; One end of planet braces is equipped with oil motor, and sun tooth is installed on the spindle nose of oil motor; The other end of planet braces is equipped with 4 planet axis and planet tooth, between each planet axis and planet tooth, the HK/20*26*25 needle bearing is installed; Two 6826 deep groove ball bearings have been installed on the cylindrical of planet braces, on the outer ring of two 6826 deep groove ball bearings, core wheel has been installed, one end of core wheel is equipped with gear ring, the end face of gear ring is equipped with front shroud, the end face of planet braces and 6826 deep groove ball bearings is equipped with backboard, between backboard and core wheel, seal ring is installed; Sun tooth is 15 teeth, and gear ring is 45 teeth, and reduction speed ratio is 3: 1; The total length of this wheel reductor is controlled in 230mm.
The beneficial effects of the utility model are: 1. the reduction speed ratio due to this wheel reductor is 3: 1, and as using the BMRW-250 motor, output torque can reach 1530N.M, has greatly strengthened driving force; 2. because the total length that makes this wheel reductor is controlled in 230mm, satisfied the requirement of vehicle-mounted sprayer to the wheel reductor total length; 3. owing to sun tooth being directly installed on the spindle nose of oil motor, and between each planet axis and planet tooth, the HK/20*26*25 needle bearing is installed, not only reduce the production assembling difficulty of planetary reduction gear, greatly extended the working life of wheel reductor simultaneously; 4. owing to using domestic oil motor, further reduced cost.
[description of drawings] the utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
In figure: 1 oil motor, 2 sun teeth, 3 planet teeth, 4 gear rings, 5 planet braces, 6 planet axis, 7 core wheels, 8 front shrouds, 9 backboards, 10.6826 deep groove ball bearings, 11, HK/20*26*25 needle bearing, 12 seal rings.
[specific implementation method] is with reference to accompanying drawing 1: an end of planet braces (5) is equipped with oil motor (1), and sun tooth (2) is installed on the spindle nose of oil motor (1); The other end of planet braces (5) is equipped with 4 planet axis (6) and planet tooth (3), between each planet axis (6) and planet tooth (3), HK/20*26*25 needle bearing (11) is installed; Two 6826 deep groove ball bearings (10) have been installed on the cylindrical of planet braces (5), core wheel (7) has been installed on the outer ring of two 6826 deep groove ball bearings (10), one end of core wheel (7) is equipped with gear ring (4), the end face of gear ring (4) is equipped with front shroud (8), the end face of planet braces (5) and 6826 deep groove ball bearings (10) is equipped with backboard (9), between backboard (9) and core wheel (7), seal ring (12) is installed.Specific operation process: a, the work of oil motor driving wheel side reducer.Input high pressure oil in oil motor (1), oil motor (1) rotarily drives sun tooth (2) rotation, sun tooth (2) drives 4 planet teeth (3) rotation, 4 planet teeth (3) drive gear ring (4) rotation, and gear ring (4) drives core wheel (7) rotation and works.The not driving wheel side reducer work of b, oil motor.Stop inputting high pressure oil in oil motor (1), wheel reductor quits work.C, wheel reductor advance and fall back.Change the direction of input oil stream in oil motor (1), by oil motor (1) forward or reverse, thereby the driving wheel side reducer advances or falls back.
Claims (2)
1. a wheel reductor that drives with oil motor is comprised of oil motor (1), sun tooth (2), planet tooth (3), gear ring (4), planet braces (5), planet axis (6), core wheel (7), front shroud (8), backboard (9), 6826 deep groove ball bearings (10), HK/20*26*25 needle bearing (11), seal ring (12), it is characterized in that: an end of planet braces (5) is equipped with oil motor (1), sun tooth (2) is installed on the spindle nose of oil motor (1), the other end of planet braces (5) is equipped with 4 planet axis (6) and planet tooth (3), between each planet axis (6) and planet tooth (3), HK/20*26*25 needle bearing (11) is installed, two 6826 deep groove ball bearings (10) have been installed on the cylindrical of planet braces (5), core wheel (7) has been installed on the outer ring of two 6826 deep groove ball bearings (10), one end of core wheel (7) is equipped with gear ring (4), the end face of gear ring (4) is equipped with front shroud (8), the end face of planet braces (5) and 6826 deep groove ball bearings (10) is equipped with backboard (9), between backboard (9) and core wheel (7), seal ring (12) is installed, the total length of this wheel reductor is no more than 230mm.
