A. measuring the mass distribution of the travelling wheel 100;
B. after the unbalance position and the unbalance size are measured, the unbalance position is de-weighted or the balance weight with corresponding weight is added in the symmetrical direction.
Specifically, because the road wheel 100 bears the weight of the whole machine, solid metal castings are mostly adopted in the road wheel 100 to improve durability and bearing capacity. The above-mentioned adding of the weight generally means attaching the weight to the side of the traveling wheel 100, and the removing of the weight generally means subtracting the metal of the side of the traveling wheel 100 by grinding.

A2. the wheel axle is axially pulled away;
A3. and taking out the travelling wheel 100, and installing the travelling wheel 100 on dynamic balance measuring equipment to measure so as to obtain the mass distribution of the travelling wheel 100.
As described above, the mass distribution of the traveling wheel 100 can be easily measured by the existing dynamic balance measuring apparatus; however, the steps are cumbersome and laborious due to the need to disassemble the road wheel 100.
For this purpose, referring to fig. 1 to 4, the present embodiment also provides a measuring part 200, the measuring part 200 including:
the main body 201 is detachably connected to the travelling wheel 100, the main body 201 is annular, a plurality of guide pieces 202 are distributed at equal angles outside, the guide of the guide pieces 202 is the same as the radial direction of the main body 201, the movable pieces 203 are arranged on the guide pieces 202, the movable pieces 203 and the guide pieces 202 have certain friction force, the travelling wheel 100 can be kept static under the action of static, but can move along the guide pieces 202 under the action of centrifugal force in a rotating state, specifically, the main body 201 is concentrically arranged on the side surface of the travelling wheel 100 in a measuring state, all the movable pieces 203 are adjusted to be closest to the center of the travelling wheel 100, then the stacker is operated, the travelling wheel 100 rotates, and the movable pieces 203 on the guide pieces 202 move away from the center of the travelling wheel 100 under the action of the centrifugal force; after the stacker is stopped and the traveling wheel 100 is kept stationary, if the moving distance of the movable member 203 is different, the mass is unbalanced.
It should be noted that, in general, the measuring component 200 is two matched components, and is respectively installed on two sides, one side, for example, 23, of the running wheel 100, and a relatively large moving distance of the movable component 203 of the position a 101 indicates that the mass of the position a 101 is heavy; by comparing the moving distance of the two-sided moving member 203, it is possible to determine whether the inner side 102 and the outer side 103 are unbalanced.
The measuring component 200 is arranged, so that disassembly is not needed when the travelling wheel 100 is subjected to quality distribution detection; and more importantly, the travelling wheel 100 and parts such as a wheel shaft and a bearing form a whole, if the travelling wheel 100 is not dismounted, the whole quality distribution can be detected, and the weight removal/weighting after the measurement result is taken out is also aimed at the whole, which definitely ensures that the whole balance is better, the whole rotation of the travelling wheel 100 is more stable, and abnormal noise is avoided.
Referring to fig. 5, the present embodiment also provides an unbalance eliminating part 300, and the unbalance eliminating part 300 includes a plurality of perforations 301 formed on the running wheel 100 and equally angularly distributed around the center of the circle thereof, and a balancing weight 302, and the balancing weight 302 is installed on the perforations 301 in the symmetrical direction according to the unbalance position. With this combination of imbalance elimination member 300 and perforable 301, mass distribution imbalance can be eliminated more conveniently, and the number and/or weight of weights 302 can be selected to more accurately eliminate mass distribution imbalance.
As an alternative embodiment, the perforation 301 is made of a smooth hole, and the weight 302 is made of an elastic material, such as rubber, so that the weight 302 can be inserted into the perforation 301 and kept in a fixed position, for example, when the inner side 102 and the outer side 103 are unbalanced, the position of the weight 302 in the perforation 301 can be adjusted to achieve balance, and the weight 302 is kept in a fixed position in the perforation 301 by means of interference fit between elasticity and the smooth hole.
In the measuring component 200 of the present embodiment, a fixing bolt 205 is disposed on the back of the main body 201, and the fixing bolt 205 is made of an elastic material, such as rubber; in the measurement state, the main body 201 may be inserted into the mounting hole by means of the fixing bolt 205 at the back and form an interference fit therewith, thereby fixing the main body 201 to the running wheel 100.
It should be further noted that, the guide member 202 on the main body 201 may be integrally formed with the main body 201 and formed by injection molding of rubber, the guide member 202 is a cylindrical body, the front end and the rear end of the guide member are provided with stop rings 204, the movable member 203 is a C-shaped metal member, the movable member 203 is clamped on the guide member 202, and the movable member 203 can maintain a certain friction force by means of a relatively rough surface of the rubber and an elastic clamping force of the C-shaped movable member 203, so that the movable member 203 is kept stationary under the static state of the running wheel 100.
As a preferred embodiment, the hole 301 is a threaded hole, and the material of the counterweight 302 after the threaded hole is used is not limited, and if made of rubber, the counterweight 302 can be directly screwed into the hole 301 without screwing, and if made of metal, threads are required to be arranged outside the counterweight 302. Of course, regardless of the material, the perforated holes 301 are better in adjusting the positions of the weights 302 in the perforated holes 301, and the balancing accuracy is higher. Further, when the screw holes are used for the through holes 301, the fixing pins 205 on the back of the main body 201 of the measuring member 200 are also stronger, and the opposing measuring member 200 is also stronger.
