General Introduction:
The reducer adopts split type box structure and shunt double reduction
involute
herringbone gear transmission. It has the advantages of high capacity, long service life,
excellent performance, and convenient maintenance.
Structure:
The reducer is installed on the base of the walking beam pumping unit and is directly
driven by the motor through the adhesive tape. Both ends of the driven shaft are equipped
with cranks. One end of the driving shaft is equipped with a sheave, and the other end is
equipped with a brake wheel with a dead brake device.
Both the driving shaft assembly and the intermediate shaft assembly adopt short
cylindrical roller bearings. The driven shaft assembly has two radial spherical roller
bearings. One end is a fixed end, and the other end is a movable end. When the reducer is
overhauled and reassembled, the bearing caps should be press
-
fitted according to the
thickness of the gaskets used by the factory. The gap at the fixed end can be eliminated
by adjusting the gasket, and the bearing cap need to be tightened with screws to prevent
oil leakage. The movable end should leave a 0.5-1mm gap between the bearing end
surface and the bearing cap, which can be realized by adjusting the thickness of the gasket.
The gears in the reducer are all lubricated by oil bath and splash lubrication. The joint
surface of the reducer box is coated with sealant. There is a two-way oil scraper between
the intermediate gear and the box base, and an oil groove is opened on the joint surface
of the box base, so that the lubricating oil splashed by the gear can flow into the oil groove
to lubricate the bearings. Three plugs are installed on the box base, the upper two are used
for checking the oil level, and the lower one is used for draining the oil. An inspection hole
is on the top of the box, and a venting cover is on the inspection hole.
