Abstract
The utility model relates to a transfer case for a vibratory roller. The transfer case is characterized by comprising a case body (1). A transmission shaft (2) is installed in the case body (1). The left end and the right end of the transmission shaft (2) are matched with the inner wall of the case body (1) through bearings (7). The center of the shaft end of the right side of the transmission shaft (2) is provided with a blind hole (8). A gap is reserved between the transmission shaft (2) and the inner wall of the right side of the case body (1). The middle of the transmission shaft (2) is provided with a transmission gear (3). The right side of the case body (1) is provided with a ventilation device. One end of the ventilation device penetrates through the case body (1) and extends into the blind hole (8). According to the transfer case for the vibratory roller, simple modification is carried out on the structure of the case body so that only air can enter the ventilation device, no oil liquid enters the ventilation device, and therefore gear oil can be prevented from being splashed out of the case body and wasted, and the transfer case is easier to achieve and lower in cost compared with other technologies.
Description
Technical field
The utility model relates to a kind of transfer case of vibratory roller, belongs to technical field of engineering machinery.
Background technique
For engineering machinery such as road rollers, owing in a lot of situations needing the power of motor to distribute transmission, therefore transfer case is commonly used, different engineering machinery has different service condition, the transfer case form of mating is also just different, and their basic principle and function are also different.
While work due to driving gear, need to add gear oil and guarantee normal effectively work, and can extend its working life, but current transfer case can run into such problem in actual motion, in the middle of the process that driving gear is running up, gear oil can splash along with the running of driving gear, and then follows air-flow together from be discharged to the outside of transfer case for the abat-vent of ventilating.So not only can cause the minimizing gradually of gear oil, form waste, and the gear oil that is discharged to transfer case outside can form stain, affect the attractive in appearance of transfer case and even whole cabin.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one can prevent that gear oil from sputtering housing, avoids gear oil waste, and the transfer case of vibratory roller with low cost.
The purpose of this utility model is achieved in that
The transfer case of a kind of vibratory roller of the utility model, it comprises casing, a transmission shaft is housed in described casing, the two ends, left and right of this transmission shaft coordinate with the inwall of casing by bearing, axle head center, described transmission shaft right side has blind hole, and the right side inwall of described transmission shaft and casing leaves gap, and the middle part of described transmission shaft is also provided with driving gear, the right side of described casing is provided with an air-breather, and one end of described air-breather is passed casing and stretched in blind hole.
On the sidewall of the casing on described transmission shaft right side, offer through hole, described air-breather stretches in blind hole after entering in casing through through hole.
Described air-breather is independent breathing pipe, or the combination of breathing pipe and hinge bolt, and in the time that air-breather is breathing pipe separately, one end of breathing pipe is stretched in blind hole after entering in casing through through hole; In the time that air-breather is the combination of breathing pipe and hinge bolt, hinge bolt inserts in casing, and its one end is stretched in blind hole, and the other end stretches in outside casing and is connected with one end of breathing pipe.
Between described air-breather and casing, be provided with seal arrangement, sealing device is combination mat.
Between described air-breather and casing, be provided with seal arrangement, described seal arrangement is seal ring or sealing gasket.
The transfer case of the utility model vibratory roller has the following advantages:
The transfer case of this vibratory roller is by simply transforming housing structure, thereby make to enter into the only having gas of hinge bolt the inside and there is no fluid, so just can avoid gear oil to sputter the outside of casing, avoid the waste of gear oil, be easy to realize compared to other technologies, and with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the transfer case of the utility model vibratory roller.
In figure: casing 1, transmission shaft 2, driving gear 3, breathing pipe 4, hinge bolt 5, combination mat 6, bearing 7, blind hole 8, through hole 9.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of transfer case of vibratory roller, comprise casing 1, a transmission shaft 2 is housed in described casing 1, the two ends, left and right of this transmission shaft 2 coordinate with the inwall of casing 1 by bearing 7, the middle part of described transmission shaft 2 is also provided with driving gear 3, transmission shaft 2 axle head centers, right side have blind hole 8, the cross section of this blind hole 8 is trapezoidal, on the sidewall of the casing 1 on transmission shaft 2 right sides, offer through hole 9, the right side of described casing 1 is provided with an air-breather, one end of described air-breather is passed casing 1 and is stretched in blind hole 8, this air-breather is independent breathing pipe 4, or being used in combination of breathing pipe 4 and hinge bolt 5.In the time that air-breather is breathing pipe 4 separately, one end of breathing pipe 4 is articulated joint, and the other end enters casing 1 through through hole 9 and stretches in blind hole 8 after interior; In the time that air-breather is the combination of breathing pipe 4 and hinge bolt 5, hinge bolt 5 inserts in casing 1, and its one end is stretched in blind hole 8, and the other end stretches in outside casing 1 and is connected with one end of breathing pipe 4.
Between described air-breather and casing 1, be provided with seal arrangement, sealing device is combination mat 6, can also be seal ring, sealing gasket etc.
Wherein, the cavity of casing 1 intermediate solid drive shaft 2 tops forms a-quadrant, and the cavity of casing 1 intermediate solid drive shaft 2 belows forms C region, and transmission shaft 2 leaves gap with the right side inwall of casing 1 and forms B region.
In the time that transmission shaft 2 and driving gear 3 run up, due to the effect of centrifugal force, gear oil can be thrown to around the outer ring of driving gear 3, and gyration center position does not almost have gear oil, when gear oil flows to along the inwall of casing 1 behind the inside of bearing 7, have operative gear oil and enter into B region from a-quadrant, but transmission shaft 2 is in the state of running up, under the effect of centrifugal force, the gear oil that enters into blind hole 8 the insides of transmission shaft 2 in B region can be thrown out of along the inclined-plane of blind hole 8, and can not enter in air-breather, finally enter into C region by the gap between bearing 7, there is no fluid so enter into the only having gas of air-breather the inside, so just can avoid gear oil to sputter the outside of casing 1, avoid the waste of gear oil, be easy to realize compared to other technologies, and with low cost.
