Abstract
Disclosed is a bearing pressure lubricating device. The utility model relates to an oil pump, wherein, a communicated T- shaped through hole is arranged on a pump body of a plunger oil pump; a plunger and a plunger spring are arranged in the traversing hole; a roller is arranged at the outer end of the plunger and is in an approach connection with a drive cam; an oil delivery ball valve, a reset spring and an oil filling valve are arranged in the longitudinal hole; the two ends of the longitudinal hole are respectively provided with an oil inlet tube and an oil outlet tube; an oil channel is arranged on the pump body at the upper end of the plunger and communicated with the pump body and an oil outlet; an overflow valve is also arranged. The utility model is of simple structure and reasonable design. The utility model is used for lubricating the 943/20 bearing in the gear box of the Shanghai New Holland tractor, with good lubricating effect. The locomotive failure caused by oil insufficiency of the bearing does not easily happen, so the comprehensive cost is low and the service life of the 943/20 bearing is prolonged.
Description
Technical field
The utility model relates to a kind of oil pump, especially relates to a kind of plunger oil pump.
Background technique
At present, 943/20 bearing in China Shanghai knob Holland gear box of tractor, be the oil that takes up by planetary pinion, splashing a bit is used to lubricate on bearing, yet, the above-mentioned practice is lubricated unreliable, 943/20 bearing often is in the oil starvation state when farm work, thereby makes it scaling loss, cause locomotive failure, quit work.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and fuel feeding is effective, is difficult for making the impaired bearing pressure lubricating fitting of bearing in the gear box of tractor.
In order to achieve the above object, the technical solution used in the present invention is: have the through hole that T shape connects on the plunger oil pump pump housing, plunger, piston spring are housed in transverse holes, in the plunger outer end roller being installed is abutted against mutually with driving cam, vertically in the hole fuel-displaced ball valve, Returnning spring and oiling valve are being housed, two-end part is equipped with respectively into and out of oil pipe in vertical hole, has oil duct and communicate with the pump housing, oil outlet on the pump housing of plunger upper end, and relief valve is housed.
The utility model has the advantages that:
Simple in structure, reasonable in design, this device is used for 943/20 bearing lubrication of Shanghai knob Holland gear box of tractor, and high lubricating effect makes bearing be difficult for oil starvation, causes locomotive failure, so overall cost is cheap, has prolonged the working life of 943/20 bearing.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is to have the through hole that T shape connects on the plunger oil pump pump housing 1, plunger 2, piston spring 3 are housed in transverse holes, in plunger 2 outer ends roller 4 being installed is abutted against mutually with driving cam 5, vertically in the hole fuel-displaced ball valve 6, Returnning spring 8 and oiling valve 7 are being housed, two-end part is equipped with respectively into and out of oil pipe 9,10 in vertical hole, has oil duct and communicate with the pump housing 1, oil outlet on the plunger 2 upper end pump housings 1, and relief valve 11 is housed.
This device driving cam is installed on the central transmission bevel pinion axle, oil pump is installed on the fine taper tooth bearing support, the plunger oil pump pump housing is opened the through hole that is connected by T shape, plunger, piston spring are housed in transverse holes, in the plunger outer end roller being housed contacts with driving cam, at vertical two ends, hole the turnover oil pipe is housed respectively, on the pump housing of plunger upper end, has oil duct and communicate, and relief valve is housed with the oil pump oil outlet.
Central authorities' transmission conelet tooth rotates and drives the driving cam rotation, because the acting in conjunction of driving cam and piston spring, plunger moves reciprocatingly, finish oil suction and pump oil process by turnover fuel tap oil feed pump, the oil that oil pump pumps is delivered to 943/20 bearing by oil outlet tube and oil duct with lubricant oil, realizes pressure lubrication, for solving the lubricated of plunger roller and driving cam, discharge a part of fluid by relief valve, be sprayed on plunger roller and the driving cam to lubricated.
