Title:
WATER PASSING DEVICE OF REDUCER CAPABLE OF DISCHARGING WATER FROM CENTER
Document Type and Number:
WIPO Patent Application WO/2020/082604
Kind Code:
A1
Abstract:
A water passing device of a reducer capable of discharging water from the center, a pipe joint (1) passing through central through holes of a reduction gearbox (4) and an output shaft (5), characterized in that an O-shaped sealing ring (2) is fitted and provided on a cylindrical fitting surface between the pipe joint (1) and the reduction gearbox (4), the pipe joint (1) is provided with an axially limiting outer retaining ring (7) before passing through the reduction gearbox (4), and is provided, after extending out of the reduction gearbox (4), with an axially limiting inner retaining ring (3) movably fitted with the pipe joint through a gap. The O-shaped sealing ring (2) is provided between the pipe joint (1) and the reduction gearbox (4) to achieve sealing, the pressure around the O-shaped sealing ring (2) is kept constant, and the case of sealing failure caused by the pressure becoming smaller due to the change of the installation manner will not occur. The pipe joint (1) is fitted and provided, after passing through the reduction gearbox (4), with the axially limiting retaining ring movably fitted with the pipe joint (1) through the gap, so that the pipe joint (1) can be prevented from disengaging from the reduction gearbox (4), and the pipe joint (1) satisfies the requirement for installing a water inlet pipe in any direction.
