Description

Technical Field

[0001] The utility model relates to the technical field of rotary joints, and more specifically, particularly belongs to a rotary joint piston used for a hot die forging clutch. Background Art

[0002] The internal separator of the hot die forged clutch rotary joint is a high-pressure area and a low-pressure area. The high-pressure area and the low-pressure area are sealed by the high-speed rotation of the rotating shaft. During use, the gap between the high and low pressure areas increases due to long-term use, and the internal oil leaks, which cannot separate the high and low pressures and make the clutch lose its function. Since the rotary joint is an imported product, the purchase cycle is long, which leads to the suspension of the production line and causes economic losses to the company. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a rotary joint piston for a hot die forging clutch, so as to improve the sealing performance of the hot die forging clutch rotary joint and reduce the cost.

[0004] The utility model provides a rotary joint piston for a hot die forging clutch, comprising a piston body, wherein the outer circle of the piston body is provided with symmetrically distributed sealing grooves, and is characterized in that an annular oil seal groove is provided at the position corresponding to the sealing groove in the inner hole of the piston body; and the coaxiality between the inner hole and the outer circle of the piston body is 0.04 mm.

[0005] Furthermore, the piston body is made of tin bronze.

[0006] The utility model provides a rotary joint piston for a hot die forged clutch. Since tin bronze has good wear resistance, tin bronze is used to remake the rotary joint piston of the hot die forged clutch, and the coaxiality of the inner and outer apertures is controlled at 0.04mm. After processing, it is repaired and scraped with the existing concentric shaft to further improve the matching accuracy and ensure that the use function is achieved. In addition, a new oil seal groove is opened at the position of the outer circle sealing groove corresponding to the inner hole of the rotary joint piston. The oil seal groove is supplied with oil through a dedicated oil circuit inside the hot die forged clutch rotary joint to improve the sealing of the hot die forged clutch rotary joint. It can be seen that compared with the prior art, the utility model does not require imported rotary joints, reduces the maintenance cycle and maintenance costs of the hot die forged clutch, reduces costs, and effectively improves the sealing performance of the hot die forged clutch rotary joint.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The utility model provides a rotary joint piston for a hot die forging clutch, comprising a piston body 1 made of tin bronze, wherein the coaxiality of the inner hole and the outer circle of the piston body 1 is 0.04 mm. Since tin bronze has good wear resistance, the rotary joint piston of the hot die forging clutch is remade with tin bronze, and the coaxiality of the inner and outer apertures is controlled at 0.04 mm. After the processing is completed, it is repaired and scraped with the existing concentric shaft to further improve the matching accuracy and ensure that the use function is achieved.

[0017] The outer circle of the piston body 1 is provided with symmetrically distributed sealing grooves 101, and the inner hole of the piston body 1 is provided with an annular oil seal groove 102 at the position corresponding to the sealing groove 101. The oil seal groove 102 is supplied with oil through a dedicated oil circuit inside the hot die forged clutch rotary joint, thereby improving the sealing performance of the hot die forged clutch rotary joint.

[0018] In summary, the utility model does not require imported rotary joints, reduces the maintenance cycle and maintenance costs of the hot die forging clutch, reduces costs, and effectively improves the sealing performance of the hot die forging clutch rotary joint.
