Problems solved by technology
[0003] The lubrication of the inner bearing of the wheel side support is very important to the performance of the wheel side support. In order to ensure the lubrication of the inner bearing of the wheel side support, the wheel side support may be designed as a closed type, such as the application number CN201520697782.9 "skid steer loader Wheel side transmission device" patent, the lubrication effect of this wheel side support is very good, but it requires high sealing performance, and the lubrication maintenance is inconvenient
Either the wheel side support is designed as an open type, that is, the bearing in the wheel side support device is lubricated by the splashed oil in the chain box, but because the outer bearing is far away from the chain box, the amount of splashed oil in the actual use process cannot fully meet the requirements. Lubrication requirements for outboard bearings, which in turn cause premature failure of outboard bearings

Embodiment Construction
[0013] The wheel side support of the skid steer loader contains two bearings for carrying. The overall structure is similar to a simple support beam structure, and the bearings are installed back to back. The present invention will be further described below in conjunction with drawings and embodiments.
[0014] like figure 1 , figure 2 , image 3 As shown, a wheel side support of a skid steer loader includes a support shaft 1, a support seat 2, a sealing ring 3, a first bearing 4, a cover 5, a second bearing 6 and a bushing 7; the support shaft 1 is relatively The supporting seat 2 performs a circular motion, and one end of the supporting shaft 1 is connected with the tire rim 8 through bolts, and the other end is connected with the sprocket 9 . The supporting shaft 1 locks the sprocket 9 through a gland and bolts, and the axial play is adjusted through an adjusting pad. The supporting shaft 1 is provided with a butter passage 11, and the butter passage 11 includes an ax...

The invention relates to a skid-steer loader wheel rim support which comprises a support shaft, a support seat, a seal ring, a first bearing, seal covers, a second bearing and a bush. The support shaft moves circumferentially relative to the support seat; one end of the support shaft is connected with a tire rim through a bolt; the other end of the support shaft is connected with a chain wheel; the support shaft is provided with grease channels comprising an axial grease channel and a radial grease channel; a tool withdrawal groove is formed in a step part of the support shaft locking the first bearing; and the seal covers comprise a first seal cover and a second seal cover. The wheel rim support sequentially comprises the support shaft, the seal ring, the first bearing, the first seal cover, the second seal cover, the second bearing and the bush in the direction from the tire rim to the chain wheel. The wheel rim support is simple in structure and convenient to manufacture, and not only can the lubrication demand of the wheel rim support be met, but also the maintainability can be effectively improved, so that the reliability and the service life of the wheel rim support are improved.
Description
technical field [0001] The invention relates to a transmission device, in particular to a wheel side support of a skid steer loader, and belongs to the technical field of engineering machinery. Background technique [0002] Skid steer loader, also known as skid steer loader, multifunctional engineering vehicle, and multifunctional engineering machine, is a special wheeled chassis equipment that uses the difference in linear velocity of the wheels on both sides to realize vehicle steering. The wheel side support device of the skid steer loader transmits the output torque of the travel motor to the tire side to realize the travel and steering functions. Therefore, the performance and maintainability of the wheel support have an important influence on the performance of the skid steer loader. [0003] The lubrication of the inner bearing of the wheel side support is very important to the performance of the wheel side support. In order to ensure the lubrication of the inner bea...
