A structure and method for supplying oil to two friction clutches at the same time. The present invention relates to a friction clutch oil supply structure and method. The present invention is to achieve the purpose of controlling two friction clutches at the same time, improving the compactness of the gear transmission device, rationally saving space, and reducing the weight of the gear transmission system. The oil inlet shaft is rotatably connected and installed in the clutch oil inlet seat. The friction clutch pressure oil inlet ring is inserted on the clutch oil inlet seat. The first oil inlet joint and the second oil inlet joint are respectively connected to the clutch oil inlet seat. The clutch oil inlet seat is processed with an oil return through hole. The first friction clutch pressure oil supply port, the second friction clutch pressure oil supply port and the friction clutch lubricating oil inlet port are processed on the oil inlet shaft. Step 1: the first oil inlet joint, the second oil inlet joint and the third oil inlet joint supply oil; Step 2: the first oil inlet joint works; Step 3: the second oil inlet joint works. Step 4: the third oil inlet joint works. The present invention belongs to the field of friction clutch work.

The utility model discloses a kind of axle sleeve of electric wheel type loader working device, belong to electric loader technical field. Including: first axle sleeve, second axle sleeve and third axle sleeve connected on swing arm are connected on movable arm;First oil feeding cavity and multiple groups of first annular grooves are opened on the first axle sleeve, and the first oil feeding cavity is communicated with first annular groove;First pin shaft is connected in the first axle sleeve;When the first oil feeding cavity sends in butter to middle first annular groove, butter flows to the first annular groove of both sides through the gap between first axle sleeve and first pin shaft;By setting multiple annular grooves in first axle sleeve, second axle sleeve, third axle sleeve respectively, replace traditional single annular groove structure, significantly increase the storage capacity of butter in axle sleeve, effectively avoid dry grinding phenomenon, reduce the incidence of pin shaft and axle sleeve abnormal wear, abnormal sound, fracture and other faults, prolong the maintenance cycle and service life of working device, improve the operation stability of loader.

The invention belongs to the technical field of ground grinding machines, and particularly relates to a ground grinding machine for indoor construction, which comprises an extrusion type water spraying assembly, a periodic pressure applying assembly, a grinding shell assembly, a planetary grinding assembly, an advancing assembly and a rack assembly, the periodic pressure applying assemblies are annularly and evenly distributed on the planetary grinding assembly, the planetary grinding assembly is rotationally arranged in the grinding shell assembly, and the advancing assembly is arranged below the rack assembly. Through periodical rotation of the planet carrier, the extrusion piston can be periodically pressed in a reciprocating mode in cooperation with the annularly-distributed slope tables, and the technical purpose of reciprocating water spraying can be achieved in cooperation with the one-way valve and the annularly-arranged spray head; compared with direct water supply through the water tank, the pressure fluctuation caused by the change of the residual water in the water tank can be eliminated, and the technical effect of maintaining the stable water supply can be achieved no matter how the residual water in the water tank is.
