Abstract
The utility model discloses a supporting wheel or a guide wheel with a combined type mud water sealing structure, which comprises a shaft (1), an outer oil seal (2), an inner oil seal (3), and the supporting wheel or the guide wheel (4). The supporting wheel or the guide wheel with the combined type mud water sealing structure is characterized in that the outer oil seal (2) is provided with four lip tongues, the inner oil seal (3) is in interference fit with the shaft (1), and the outer oil seal (2) is in interference fit with the supporting wheel or the guide wheel (4). All the components of the supporting wheel or the guide wheel are in interference fit with each other. When the inner oil seal and the outer oil seal are assembled together, a sealed space is formed by tightly attaching the four lip tongues, thereby being capable of effectively preventing water and mud from entering the space between the inner oil seal and the outer oil seal, being capable of effectively preventing lubricating oil in a bearing from leaking, guaranteeing a good working environment of bearing lubrication cleaning, and prolonging service life of the bearing.
Description
Technical field
The utility model relates to a kind of caterpillar wheel or track adjusting wheel with compound type muddy water hermetically-sealed construction.
Background technology
The caterpillar wheel on facility chassis such as caterpillar band self-propelled reaper, rotovator, track adjusting wheel etc. because of it is worked in dry land, paddy field, fluid mud field for a long time, tend to make its early failure because of entering such as water, mud cause wear-out of a bearing, axle wearing and tearing.
Summary of the invention
The purpose of the utility model be to provide a kind of simple in structure, can effectively prevent sealing, mud get in the caterpillar wheel or the track adjusting wheel of band compound type muddy water hermetically-sealed construction between the outer oil seal.
The technical scheme that the utility model adopted is: a kind of caterpillar wheel or track adjusting wheel with compound type muddy water hermetically-sealed construction; Comprise outer oil seal, inner oil seal, axle, caterpillar wheel or track adjusting wheel; It is characterized in that: said outer oil seal has four road words; Between inner oil seal and the axle is interference fit, is interference fit between outer oil seal and caterpillar wheel or the track adjusting wheel.
Take interference fit between each parts of the utility model; Fit tightly by four road words when inside and outside oil sealing fits together and form a fully enclosed space; Both can prevent effectively that sealing, mud got between the interior outer oil seal; Can effectively prevent the oil leak in the bearing again, guarantee the works fine environment of bearing lubrication cleaning, the service life of improving bearing.
Description of drawings
Fig. 1 is the constructional drawing of the utility model.
The specific embodiment
According to the accompanying drawing and the specific embodiment the utility model is described further below:
Can know that from Fig. 1 the utility model comprises axle 1, outer oil seal 2, inner oil seal 3, caterpillar wheel or track adjusting wheel 4, outer oil seal 2 has four road words, is interference fit between inner oil seal 3 and the axle 1, is interference fit between outer oil seal 2 and caterpillar wheel or the track adjusting wheel 4.
The described enforcement of the utility model is the description to the preferred embodiment of the utility model; Be not that scope and design to the utility model limits; Various modification under the prerequisite that does not break away from the utility model design philosophy and improvement all should fall into the protection domain of the utility model, and the protection content of the utility model all is documented in claims.
