The rim and its bearings are individually subjected to interference without interference, so that the rims and bearings that are most prone to wear and tear can be extended in service life, and the rims and bearings on each side can be replaced and repaired separately, thus making maintenance and repair more Easy and reduce the cost of repairs.

Description

Improvement of the track roller of agricultural machinery

The present invention relates to a roller on a track of a track-type agricultural machine. The roller is a rim that is symmetrical in two halves and is axially disposed on the axle through a bearing so that the rim can freely rotate.

The main advantages of crawler-type agricultural machinery are: less slippage, large traction, wide contact area between the track and the ground, easy to pass the uneven or slack ground, and can greatly reduce the center of gravity of the agricultural machine, making it more suitable for slope work, and at the same time A smaller turning radius is provided, making the rotary operation of the agricultural machine easier.

Generally, the main structure of the track wheel of the agricultural machine includes: a driving wheel and a driving wheel which are arranged on the front and rear ends of the chassis, and a plurality of rollers are arranged between the main and the passive wheels, and the roller is usually a road wheel. , the brake wheel, the support wheel, etc., as disclosed in the publication No. M439001, which mainly comprises a track frame and a support frame fixed on the track frame on one side, wherein the track The front end of the rack is equipped with a driving wheel, and the driving wheel train is connected to the transmission mechanism of the agricultural machine, and then the driving wheel set is driven by the power transmitted by the transmission mechanism; a braking wheel is respectively arranged at the front end and the rear end of the supporting frame; a driven wheel, and the support frame is provided with a plurality of wheel sets between the brake wheel and the driven wheel, and then a rubber track is wound around the outer circumference of the wheel; and the brake wheel can provide the function of the brake when necessary. To avoid danger; and further to support the frame in the last wheel set A support wheel is arranged between the driven wheels, so the aforementioned support frame is a part of the chassis, and the brake wheel, the driven wheel, the wheel set, the support wheel, etc. are collectively referred to as a roller, or as disclosed in the Patent No. 136779 The idler wheel and the runner, or the roller of the publication No. 321144, are also referred to as the roller. The structure of the roller is generally as shown in Fig. 1, and mainly includes a chassis that can be locked in the agricultural machine. A wheel axle 1 is disposed on the axle 1 and a roller 3 is axially disposed through the bearing 2. The wheel body of the roller 3 is provided with a symmetrical rim 31 at both ends thereof, and a rim is formed between the two rims 31. The groove 32 in the middle of the crawler belt induces the groove 32 received by the tooth, and at the same time, the two sides of the induction tooth in the middle of the track and the inner sides of the two rims 31 abut each other, so that the track does not slip off the roller 3.

At the same time, the support wheel in the roller is installed on the inner side of the upper crawler belt to support the crawler belt to prevent it from sagging, and the roller installed on the inner side of the lower crawler belt is a load wheel for taking the weight of the whole agricultural machine. And the track is flat on the ground to increase the grip, while the agricultural machine is undulating on the uneven ground, so that the contact friction between the rollers and the track is always maintained.

Since the aforementioned roller 3 is a load wheel that bears the weight of the entire agricultural machine, the structure is designed to be applicable to the original vehicle weight, and the rim 31 and the bearing 2 which are most easily worn should also be used. Lifespan, however, because the farming area in Taiwan is generally too small, the turning and turning of the agricultural machinery during operation will be too frequent, plus the aforementioned roller 3 when the agricultural machine is driving on uneven ground, or turning and turning, the longitudinal direction of the track At different positions before and after, different heights and undulations may occur, and the inner side and the outer side of different positions before and after the crawler may also have different heights and undulations, and when turning and turning, both sides of the roller 3 may be caused. The rim 31 causes a difference in the rotational speed of the inner and outer rims 31 with respect to the crawler belt. However, since the rims 31 on the both sides are integrally formed rollers 3, the rims 31 on both sides are not freely rotatable, and the crawler belts are transmitted. The frictional force and stress of the rims 31 on both sides form a torque force, which is installed on the rim except that the rim 31 is easily worn. The inner bearing 2 of the 31 also causes abnormal loss, that is, the roller 3 is particularly prone to wear and damage when turning or turning, which causes frequent repairs and an increase in cost.

The reason is that in order to improve the roller in the conventional crawler belt, the rims on both sides are integrally formed, so that the agricultural machine runs on the uneven ground, or the frictional force of the track forms an abnormal torque force when turning and turning. The bearing and the bearing installed in the rim are very easy to be damaged, which leads to the need to replace the entire roller or all the bearings from time to time, resulting in an increase in the cost of repairing and replacing components. The present invention provides the two symmetry of the roller. The rim, and the two rims are respectively disposed on the axle through the bearing shaft, so that the two rims are freely rotated, and the rim and the bearing respectively bear the friction and stress of the side without mutual interference and damage at the same time. Only the rims and bearings on each side can be repaired and replaced, which makes the maintenance and replacement cost of the components more economical.

The technical solution adopted by the present invention to solve the technical problem is: a roller comprising a shaft on a shaft, which is symmetrical in each other and symmetrical on each of the rims of the bearing shaft, and two rims A groove is formed between them.

Therefore, through the above-mentioned novel roller, the rim is symmetrical and can rotate freely, so that each side rim does not interfere with each other due to the load of friction and stress, so the rim and the bearing The load of abnormal friction and stress is minimized, thereby extending the service life of the rim and the bearing, or when the bearing of one side rim and its shaft is damaged, only the side rim or its bearing needs to be replaced. That is, the rim that is not damaged on the other side can be used continuously, which makes the maintenance easier and reduces the cost of maintenance.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic cross-sectional view showing the structure of a roller on a crawler of the conventional agricultural machine.

2 is a schematic cross-sectional view showing the structure of a roller on the crawler of the agricultural machine of the present invention.

Referring to FIG. 2, each of the rollers 3 mounted on the inner side of the crawler belt is disposed on a wheel axle 1 which is locked on the chassis of the agricultural machine, and the roller 3 is symmetrical by two halves. The rim 31 is disposed on the axle 1 immediately adjacent to the shaft, and each of the side rims 31 is respectively disposed on the axle 1 through the bearing 2, so that the respective side rims 31 can be freely rotated, and at the same time, the two rims are respectively A groove 32 is formed between the 31s for passing the transmissive teeth in the middle of the inner side of the track; and further, a grass cover 4 is disposed adjacent to the two rims 31.

Therefore, when the agricultural machine runs on an uneven ground, or turns or turns, the rollers 3 in the crawler belt will generate an inner wheel difference, but since each side rim 31 is transmitted through the bearing 2, it can be freely on the axle 1 respectively. Rotating, so the friction and stress generated by the load are not interfered by the rim 31 of the side and the bearing 2 at the first time, so the abnormal friction between the rim 31 and the bearing 2 is The stress load is minimized to extend the service life of the rim 31 and the bearing 2.

Moreover, the rim 31 on both sides of the roller 3, if the rim 31 and the bearing 2 on the side with a large load are damaged first, it is only necessary to repair and replace the rim 31 and the bearing 2 of the side damage, so that Maintenance work is simpler and easier, and it also reduces the cost of repairs.
