Abstract
The invention discloses a belt driven continuously variable transmission (CVT) driving wheel, and belongs to an engine driving structure. The driving wheel comprises a main shaft, a fixed disk and a box body sleeved on the main shaft; a dust cover extended to the box body and adapted with the size of the box body is arranged on the fixed disk; and the dust cover is blocked on the outer wall of the box body, a narrow space is formed among the dust cover, the box body and the main shaft, and the dust passing area is reduced. The probability that dust granules generated in the working process enter the joint of an oil seal and the main shaft is greatly reduced through the dust cover arranged on the fixed disk, so that the lip of the oil seal is protected from being damaged and the sealing property of the oil seal is improved.
Description
Technical field
The present invention relates to a kind of engine-driving structure, relate in particular to a kind of bel-drivenn CVT driving wheel.
Background technique
In the CVT transmission system, main shaft drives the rotation of CVT driving wheel, and the moment of torsion that produces is delivered on the follower by belt, has realized the transmission of moment.Belt produces the junction point that a large amount of dust granules can enter oil sealing and driving wheel in the course of the work, causes the damage of oil seal lip, causes leakage of oil and oil impregnate phenomenon, thereby reduces the CVT oil sealing sealing.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of dust that prevents influences the bel-drivenn CVT driving wheel of oil sealing sealing.
Technological scheme: for solving the problems of the technologies described above, bel-drivenn CVT driving wheel of the present invention comprises main shaft, fixed tray and is set in casing on the main shaft, on fixed tray, be provided with to casing extend and with the adaptive dust-proof cover of casing size.
Described dust-proof cover is stuck on the cabinet exterior, and dust-proof cover and casing, main shaft form small space, thereby prevent that dust from entering oil seal lip.
Beneficial effect: the dust-proof cover of bel-drivenn CVT driving wheel of the present invention by on fixed tray, being provided with; reduce the probability that the dust granules that produces in the course of the work enters the junction of oil sealing and main shaft greatly; thereby the protection oil seal lip can not destroy, and improves oil sealing sealing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1, bel-drivenn CVT driving wheel of the present invention comprises main shaft 1, and fixed tray 2 is set in the casing 3 on the main shaft 1, is provided with oil sealing 5 between casing 3 and the main shaft 1, and oil sealing 5 prevents leakage of oil and oil impregnate when guaranteeing to lubricate.On fixed tray 2, be provided with to casing 3 extend and with the adaptive dust-proof cover 4 of casing 3 sizes, this dust-proof cover 4 is stuck on casing 3 outer walls, forms small space with casing 3, main shaft 1, the area that passes through that dust enters reduces.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
