Embodiment Construction
[0018] Coal shearer rocker arm thin oil automatic centralized lubrication system, such as figure 1 As shown, it includes a rocker arm housing 1, a lubricating oil pump 2, and a multi-stage gear transmission mechanism arranged in the rocker arm housing and containing a second transmission shaft 3. The lubricating oil pump is installed in the rocker arm housing as the lubricating oil tank. The arm shell is outside and connected to the second drive shaft drum side; the rocker arm shell is provided with an oil suction port or an oil discharge port located at the lower part of the high-speed cavity and an oil discharge port or an oil suction port located at the lower part of the low-speed cavity. The oil inlet is connected to the oil suction port on the rocker arm housing through the oil inlet pipe 4. A ball valve 8 and a filter 9 are installed on the oil inlet pipe 4. The ball valve is located between the filter and the rocker arm housing. The filter adopts a CGQ magnetic suction fil...

The invention relates to a shearer part, in particular to an automatic central thin oil lubrication system for shearer rockers, and solves the problem that poor lubrication of the existing shearer rockers causes failure of automatic, quantitative and precision lubrication for heavily loaded friction pairs of the rockers. The automatic central thin oil lubrication system for shearer rockers comprises a rocker shell, a lubricating oil pump, and a multistage gear drive comprising a second drive shaft. The rocker shell is provided with a sucker hole and a discharge hole. An oil inlet of a lubricating pump is communicated with the sucker hole through an inlet pipe. An adjustable distributor is installed on an outlet pipe, and an LQ-type pipeline oil flow indicator is added to an oil outlet of the adjustable distributor. The automatic central thin oil lubrication system for shearer rockers is simple in structure, reasonable in design and simple to operate, enables quality and intelligence level of shearers to be higher and failure rate of the shearers to be lower, enables the shearers to be more reasonable in structure and higher in reliability, and is energy-saving, environment-friendly and widely applicable.
Description
Technical field [0001] The invention relates to a coal shearer component, in particular to a coal shearer rocker arm thin oil automatic centralized lubrication system. Background technique [0002] With the gradual improvement of the working reliability of the shearer and the rapid development of the intelligent level, it is necessary to put forward higher requirements for the lubrication system of the shearer. Because the shearer has been in the coal mine for a long time, the working environment is very harsh, the surrounding space is small, the dust is large, the explosion-proof conditions are harsh, the structure of the shearer is compact, and the cutting load of the rocker arm is large. Automatic, reasonable and accurate lubrication of each movement friction pair is very necessary. Moreover, the automatic centralized lubrication of the shearer is also the focus and difficulty at this stage. [0003] When the shearer is cutting, the gears and bearings in the rocker arm have a ...
