Abstract
The utility model particularly relates to a crane wheel set. An adjustable wheel set comprises a wheel (1), a wheel rack (2), a circular bearing box (3), a wheel axle (4), a circular bearing box (3), a dustproof cover (5), a self-aligning bearing (6) and a connecting bolt set (7), wherein the circular bearing box (3) is provided with N wire holes (9) which are uniformly distributed in a same circumference, and the eccentric distance between the circle center of an inner hole (for installing the self-aligning bearing (6)) of the circular bearing box (3) and the circle center of the circumference on which the N wire holes are located is L; and M light holes are respectively distributed in the two side surfaces of the wheel rack (2), the M light holes and the N wire holes are formed in a same circumference, and the M light holes are overlapped with M wire holes in the N wire holes. When a wheel deflects and is required to be adjusted, the purpose of adjusting the wheel can be achieved just by rotating the circular bearing boxes on one or two sides, and then the bolt set passes through the light holes in the wheel rack and the wire holes in the circular bearing box and then is screwed down. The adjustable wheel set disclosed by the utility model can effectively adjust the deflection of wheels, and also can adjust the height difference of wheels.
Description
Technical field
The utility model belongs to the weight-lifting equipment technical field, particularly a kind of crane locomotive wheels.
Background technology
When the set of wheels of hoisting crane adopts the round bearing box structure, can only rely on the whole working accuracy of crane end carriage or bogie frame and reduce the horizontal and vertical deflection that welding deformation between the beam of main side is controlled wheel.But be subjected to the impact of the factors such as equipment precision and manufacturing process, unsatisfactory to the declination control of wheel, cause hoisting crane that the wheel gnawing rail phenomenon in use occurs.
The utility model content
The purpose of this utility model is: providing a kind of can adjust in installation process, and control wheel horizontal and vertical deflection prevents that wheel from gnawing the set of wheels design plan of rail
The technical solution of the utility model is: a kind of adjustable wheel group comprises: wheel, vehicle wheel frame, round bearing case, axletree, round bearing case, cover of dust, tilting bearing, tie bolt group; It is characterized in that:
Well-distributed N silk hole arranged on the faying face of described round bearing case and described vehicle wheel frame on same circumference, and the center of circle eccentric throw of the center of circle and described N place, hole circumference that described round bearing case is installed the endoporus of described tilting bearing is L;
Described vehicle wheel frame is provided with the circular hole that matches with described round bearing case bossing cylindrical, and the side-lower of described circular hole has a breach that when assembling described round bearing case is passed through; The two sides of described vehicle wheel frame are distributed with M unthreaded hole, a described M unthreaded hole on vehicle wheel frame take described circular hole as the center of circle, and with described N silk hole on same circumference, and coincide with wherein M hole.
Second technical scheme is: adjustable wheel group as previously discussed is characterized in that: described N=24; Described M=4; Described eccentric throw is that L is 3mm; 4 unthreaded holes are spaced apart 60 °.
The 3rd technical scheme is: aforesaid adjustable wheel group is characterized in that: maximum inner eccentric holes place makes marks on described round bearing case outside face.
When the wheel deflection need to be adjusted, only need to rotate one or both sides round bearing case, after reaching the purpose of adjusting deflection, again the bolt group is passed unthreaded hole and the silk hole on the round bearing case on the vehicle wheel frame and tighten and get final product.The utility model dismounting is convenient, and is easy to adjust and precision is high, can effectively adjust the deflection of wheel, and rail is gnawed in prevention, and the while also can be adjusted the difference of height of wheel.

The specific embodiment
Embodiment 1: referring to accompanying drawing, a kind of adjustable wheel group comprises: wheel 1, vehicle wheel frame 2, round bearing case 3, axletree 4, round bearing case 3, cover of dust 5, tilting bearing 6, tie bolt group 7; It is characterized in that:
Well-distributed N silk hole 9 on same circumference arranged on the faying face of described round bearing case 3 and described vehicle wheel frame 2, and the center of circle of the endoporus of the described tilting bearing 6 of described round bearing case 3 installations and the center of circle eccentric throw of described N silk place, hole circumference are L;
Described vehicle wheel frame 2 is provided with the circular hole that matches with described round bearing case 3 bossing cylindricals, and the side-lower of described circular hole has a breach that when assembling described round bearing case 3 is passed through; The two sides of described vehicle wheel frame 2 are distributed with M unthreaded hole, a described M unthreaded hole on vehicle wheel frame 2 take described circular hole as the center of circle, and with described N silk hole on same circumference, and coincide with wherein M hole.
Embodiment 2: as described in Example 1 in the adjustable wheel group, and described N=24; Described M=4; Described eccentric throw is that L is 3mm; 4 unthreaded holes are spaced apart 60 °.
Embodiment 3: for easy to adjust, in embodiment 1 or 2 described adjustable wheel groups, maximum inner eccentric holes place makes marks 8 on described round bearing case 3 outside faces.
Claims (3)
1. an adjustable wheel group comprises: wheel (1), vehicle wheel frame (2), round bearing case (3), axletree (4), round bearing case (3), cover of dust (5), tilting bearing (6), tie bolt group (7); It is characterized in that:
