Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples:
as shown in fig. 1 to 4, a rotary oil supply device comprises an oil block main body 1, a rotary shaft 2, a thrust bearing 3, an oil supply port 4 and an oil return port 5, wherein a through round hole is formed in the center of the front surface of the oil block main body 1, an oil passage groove 6 and a sealing member groove 7 are formed in the round hole, an electromagnetic directional valve fixing screw hole 8, an input oil passage 9 and an output oil passage 10 are formed in the upper portion of the side surface of the oil block main body 1, the input oil passage 9 and the output oil passage 10 respectively correspond to oil inlet and outlet holes of the electromagnetic directional valve 11, the input oil passage 9 respectively communicate with the oil supply port 4 and the oil return port 5, the output oil passage 10 is communicated with the oil passage groove 6, an oil passage 12 is formed in the rotary shaft 2, one end of the oil passage 12 is opened to an end of the rotary shaft 2 and connected with a hydraulic actuating component, the other end of the oil passage 12 is opened to the side surface of the rotary shaft 2 and corresponds to the position of the oil passage groove 6, a circular disc is formed in the inner end of the circular disc, a notch 15 is formed in the inner end surface of the circular disc, the thrust bearing 3 is fixed in the notch 15, one end opposite to the oil outlet end of the rotary shaft 2 is provided with a shaft gland 13, the inner end of the shaft gland 13 is provided with a notch 15, the notch 15 is fixedly in the inner end of the notch 15, the notch 15 is formed in the inner end of the thrust bearing 3, the thrust bearing 3 is fixedly in the inner end of the thrust shaft 3 is connected with the metal gland 2 through the metal gland 2, and the rotary shaft 2 is a cylinder gland through the rotary shaft 2.
The working principle of the rotary oil supply device is as follows: the sealing element is arranged in the groove of the oil outlet end of the rotating shaft center, the thrust bearing is arranged in the groove of the gland of the shaft center, and the thrust bearing is arranged in the groove of the gland of the shaft center and is connected with the rotating shaft center through bolts. The electromagnetic reversing valve is fixed on the upper side surface of the oil path block main body through bolts and is connected with an oil supply and return pipeline, pressure oil supplied by a hydraulic oil source enters the electromagnetic reversing valve through an input oil path, is distributed through the reversing valve and then enters and exits each oil path groove respectively, enters and exits each oil path on the side surface of the rotation axis through the oil path groove, and is communicated with the hydraulic execution part through an oil port at the end head of the rotation axis.
