Technical background:
It is a problem that difficulty is very big that double-steel wheeled vibratory presses the road rammer compacter to turn to problem, so easy unlike motor turning, and domestic and international hydraulically powered twin-tub wheel road roller is to adopt hydraulic push rod, realize turning to huge hydraulic thrust, and the twin-tub of our utility model wheel vibration pressure road rammer compacter is to adopt non-Hydraulic Power Transmission System; In addition, if employing rack gear, to need to increase a cover motor, reductor system again, structure is bigger, and it is complicated, do not reach the control effect, turn to manually and adopt, its steering force is controlled at the labour intensity requirement that could adapt to the people below 10 kilograms at most, the vibration frequency of adding vibrating body is up to per minute 1500 times, and the limit that the people can bear must be below 60 times, and its degree of freedom reaches 6 directions, and the utility model is exactly that ingenious employing conventional mechanical structure solves this labyrinth easily.
Summary of the invention:
The purpose of this utility model provides a kind of steering mechanism manually that can overcome the double-steel wheeled vibratory roller of above-mentioned shortcoming.
For achieving the above object, the technical scheme that the utility model provides is: the frame of road roller is connected by roller bearing and afer bay, gear wheel is rigidly connected by gear shaft and afer bay, the rotation reducer pedestal is housed on the frame, rotate fixedly connected reductor on the reducer pedestal, fixedly connected steering spindle stop sleeve on the reductor, the steering spindle support set is arranged in the steering spindle stop sleeve, steering spindle support set bottom is connected with the reductor power shaft by key, square hole and steering spindle are arranged in the steering spindle support set, and square hole cooperates the realization steering spindle to rotate and slide up and down with steering spindle lower end square toes; Be fixed with steering wheel on the vibration damper plate and support block set, top cooperates with last axle by rolling bearing pedestal, and last top square head portion is connected with steering wheel square hole and screw, and last is connected with steering spindle by pin and axis and pin and lower shaft.Steering wheel rotation drive to be gone up in the pivot pin pivot pin and lower shaft and axis of orientation and is overcome swing all around and rotate, thereby axis of orientation axle sleeve reductor power shaft, output shaft, pinion, gear wheel are rotated, and forces the gear shaft afer bay and turns to roller steering.
Transmission process of the present utility model is: the cardan axis that steering wheel rotation connects rotates (adopt cardan axis mainly to overcome steering spindle and be subjected to four direction oscillatory forces all around) and drives and have the steering spindle support set of square hole to rotate in supporting with it, (steering spindle is rotated to do in the axle support set that can also rotate at the same time and is slided up and down, draw the rotation that rings axle to overcome the vibration damper plate bob), thereby driving the reductor power shaft rotates, drive the pinion rotation that links to each other with speed reducer output shaft simultaneously, also force the gear wheel that is meshed with pinion to rotate, drive the afer bay that is connected as a single entity with Large Gear Shaft During simultaneously again and rotate, thereby make afer bay and the following roller rotation that turns to reach the purpose that turns to.
The utility model can reach running beneficial effect reliable, easy to operate, with low cost by above technical scheme.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment:
See shown in the accompanying drawing 1:
Present embodiment is mainly by afer bay 1, install and turn to roller 37 in its lower section, frame 2, roller bearing 3, gear wheel 4, key 5, round nut stop washer 7, round nut 8, gear shaft 9, vibration damper plate 10, steering spindle axle sleeve 11, screw 12, steering wheel 13, rotating shaft gland 14, rolling bearing 15, last axle 16, pin 17, axis 18, lower shaft 19, pin 20, bearing gland 21, rolling bearing 22, steering spindle 23, steering spindle support set 24, bolt 25, spring 26, key 27, axle sleeve 28, reductor 29, bolt 30, turn to reductor seat board 31, pinion 32, key 33, back-up ring 34, bolt 35, bracing frame 36, turn to roller 37 formations such as grade.
Afer bay 1 bottom is equipped with and turns to roller 37, turn to roller 37 by roller bearing 3,4 cooperate with frame 2, gear shaft 9 by afer bay 1 top, key 6 is connected with gear wheel 5, be equipped with on the frame 2 and turn to reductor bed plate 31, turn to be equipped with on the reductor bed plate 31 and turn to reductor 29, reductor 29 output shafts are equipped with and gear wheel 5 pinion in mesh 32 by key 33, reductor 29 top power shafts link to each other with turning to support sleeve 24 by key 27, support set 24 fit ons are in steering spindle axle sleeve stop sleeve 11, be combined with the steering spindle 23 of square toes in the steering spindle support set 24 in the slideway of square opening, steering spindle 23 is by compression spring 26, rolling bearing 22, bearing gland 21, be fixed in the steering spindle axle sleeve stop sleeve 11, can only rotate with suitably mobile up and down.Steering direction dish 13 is gone up axle 16, pin 17, axis 18 lower shafts 19, pin 20 and steering spindle 23 rotations by connecting bolt 12 drives, because steering spindle 23 bottoms are square toes, thereby also drive endoporus is the axle sleeve 28 of square hole and the reductor 29 power shafts rotation that connects with key 27, drive pinion 32 rotations that reductor 29 output shafts and key 33 link to each other simultaneously, also force gear wheel 5 and key 6 Large Gear Shaft During 9 to be rotated, drive the afer bay 1 that is connected as a single entity with Large Gear Shaft During 9 simultaneously and rotate, thereby make afer bay 1 and following roller 37 rotations that turn to realize that two steel wheels turn to.
Steering spindle 23 tops reach upward by pin 20 and lower shaft 19, pin 17 with axis, and pivot hinge is connected, vibration damper plate 10 is fixed with bracing frame 36, bracing frame 36 tops cooperate with last axle 16 by the axis of rolling 15 to be fixed on the bracing frame 36, steering wheel 13 bottom square openings are inserted in axle 16 square toes and are tightened up by screw 12, after be enclosed within bracing frame 36 tops with rotating shaft gland 14 again.Like this on vibration damper plate 10, artificial easily rotate with bracing frame 26 that vibration damper plate 10 solidity are connected on steering wheel 13, axle 16 axis, 18 lower shafts 19 and steering spindle 23 are rotated, the steering spindle square shaft has the steering spindle support set 24 of square hole to rotate by interior, and make and turn to reductor 29 pto input shafts to rotate, also make pinion 32 and stir gear wheel 15 rotations, force gear shaft 9 and afer bay 1 and turn to roller 37 to rotate, and realize the purpose that road roller turns to.Frame 2 afer bays 1 are along with the vibrating wheels vibration so, then the gear wheel 5 on the frame 2 turns to reductor 29 and steering spindle axle sleeve support set sleeve can produce up and down 6 direction random motions all around, steering wheel rotation is then gone up axle 16 axis, 17 lower shafts 19 and is sold to adapt under the swing situation all around and rotate, and the square toes of steering spindle 23 adapt to up-down vibration in steering spindle support set 24 inner springs control slip.
The example of the above is a preferred embodiments of the present utility model only, is not that this limits practical range of the present utility model, so all equivalences of doing according to the shape structure and the principle of utility model change, all should be covered by protection domain of the present utility model.
