The supporting wheels are utilized to help the heaviness of the work vehicle while moving on the track rails (rail connections) or track plates, and they are likewise used to limit the tracks and forestall sidelong slippage. It is additionally used to limit the tracks and keep them from slipping sideways. At the point when the farm truck is turned, the supporting wheels power the tracks to slide on the ground.
They are frequently in mud, water and dust and are dependent upon solid effects, so they require solid fixing and wear-safe edges.
Capacities and necessities
The capacity of the supporting wheel is to move the heaviness of the train set to the ground and to move it on the tracks. To forestall wrecking, the supporting wheel ought to likewise have the option to keep the tracks from moving horizontally comparative with it.
The supporting wheels regularly work in mud, water and sand and are exposed to solid shocks, making the functioning conditions amazingly unforgiving and the wheel edges effectively worn.
The prerequisites for the supporting wheel are: wear-safe wheel edge, dependable bearing seal, low moving opposition, and so forth
Type
The sort of supporting wheel utilized for blend tracks and indispensable or elastic tracks is unique: for mix tracks the supporting wheel rolls on the aide rails while for basic or elastic tracks the supporting wheel rolls on the track plate.
There are two sorts of help wheels for mix tracks, as displayed in Figure 1 underneath. One is single flanged and the other is twofold flanged. The previous sort is simpler to produce; hence it is all the more usually utilized and the last option is less ordinarily utilized. The reason for having a spine is to keep the track from moving horizontally comparative with it, to forestall wrecking when turning. The tallness of the spine is normally h = 10-20 mm. To diminish the rubbing between the side of the edge and the side of the track, the side of the edge is frequently made into a slant, with a slant point of α = 20°~30°
Basic or elastic tracks, which have raised pectine teeth projected on the inward surface of the track plate to forestall sidelong development of the track against the supporting wheels, have a level supporting wheel edge without a rib. In any case, each supporting wheel should have a twofold line of edges, as displayed in Figure 2 underneath.
Fig. 2 Supporting wheel with twofold line edge
The quantity of supporting wheels can make the ground tension of the track all the more even, so that strolling on wet and delicate soil can diminish drooping, yet then again, in light of the fact that the length of the track is sure, the quantity of supporting wheels is more, then, at that point, the distance across of each should be little, china Track Roller Factory which builds the moving obstruction, for the most part talking as the track strolling instrument of the consolidate collector, the quantity of supporting wheels is frequently 3 to 4, a couple with 6.
Measurement of the supporting wheels
also the pitch of the track
ought to be generally in the accompanying proportion.
For consolidated tracks
For solid or elastic tracks
Plain direction (for example iron-based powder metallurgical oil direction) are frequently utilized for the supporting wheels, yet moving course are likewise utilized. Whichever bearing is utilized, it is fundamental to forestall the entrance of mud and water.
The edge of the supporting wheel ought to be wear safe and is by and large made of 45 measure steel with a solidified surface of at least HRC53.
Issues that might emerge
(1) Wear of the wheel body. This happens on the grounds that the steel utilized isn’t qualified or that the material is heat-treated with a low hardness and deficient wear obstruction.
(2) Oil spillage. The shaft of the supporting wheel has been pivoting through the sleeve, and the wheel body must be greased up with oil, however assuming the seal is supposed to be terrible, it is not difficult to create the peculiarity of oil spillage, so the shaft and the sleeve are handily exhausted without oil, making the item not be able to be utilized. There are a few purposes behind oil spillage as follows: 1. drifting oil seal isn’t qualified; 2. item sleeve roundness adequately isn’t; 3. support shaft shine adequately isn’t; 4. gear oil isn’t up to norm; 5. handling size resistance, etc. These issues will cause the oil spillage of the supporting wheel.
Oil spillage check and prohibition
- During the establishment interaction, severe review ought to be done by the specialized prerequisites of the parts to hold them clean and forestall debasements back from entering the establishment surface. Particularly the fixing end face of the fixing ring, even a small residue molecule can obliterate the seal and lead to oil spillage.
2, fixing sleeve, fixing elastic ring maturing, misshapening, scars, burst, and so on should be supplanted with new items.
3、The spring ought to be supplanted when the spring power is inadequate, and its end surface can be ground level. At the point when the tension ring twist ought to be fixed and evened out, eliminate the sharp edge.
4, huge and little fixing ring contact isn’t severe, can be reground, so it has a uniform constant crushing ring belt. Try not to contact the ring end face and disturb the mate ring. The thickness of the ring ought to be predictable, if not it should be supplanted.
5、The thickness of the elastic ring adequately isn’t, it is permitted to wrap the asbestos rope to make it arrive at a snugness of/0.15~0.20kg per square centimeter.
6、The hub is twisted, not round or the neck is worn, the center point of the supporting haggle fixing shell with the pieces of the belt are worn should be fixed.
7, bearing and fixing ring plane wear, as per the level of wear, in the fixing sleeve and center point end face between the cushion with 2 ~ 4 mm thick oil-safe elastic ring. After gathering, the seal sleeve get together ought to have the option to pivot openly on the center point. Then again the bearing external ring can be gasketed with a 100 mm external measurement, 85 mm internal distance across and 1.5 mm thickness between the fixing lodging support shoulder to make up for how much bearing wear. At the point when the tallness of the fixing sleeve is under 32 mm, the bearing width is under 41 mm, ought to be supplanted with new items. - The paper cushion on the supporting wheel ought to be kept unblemished and of reasonable thickness [3] .
