The invention discloses an OH3 pump provided with an oil
lubrication box body structure, which comprises a bearing box body arranged on the outer side of a rotating shaft, an
oil storage ring is arranged at the bottom of the bearing box body, a pump efficiency ring is arranged at the center of the
oil storage ring, an oil flinger is arranged in the middle of the bearing box body, the pump efficiency ring and the oil flinger are sleeved on the rotating shaft, and the pump efficiency ring is used for pumping lubricating oil in the
oil storage ring into the oil
lubrication box body. The oil cup is arranged at the bottom of the bearing box body, is pumped into an oil storage bin on an oil guide disc on the top of the bearing box body along an output oil way, falls on an oil flinger from the upper part through an oil way loop, and is dispersed to all parts of the bearing box body along with the rotation of the oil flinger. Traditional
grease lubrication is replaced by oil lubrication,
temperature resistance is higher, the bearing operates stably, meanwhile, the bearing box and other parts are sealed better integrally, impurities such as
silt particles are prevented from entering the bearing, and the service life of the bearing is prolonged.
