Embodiment Construction
[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0014] figure 1 and figure 2 The dust-proof and waterproof protection structure of the generator bearing shown includes a generator front cover 1, a rotating shaft 2 and a pulley 3. The inner center of the generator front cover 1 is provided with a transmission hole 4 matching the rotation shaft 2, and the transmission hole 4 A ball bearing 5 is clipped and fixed inside, and the rotating shaft 2 traverses through the inside of the ball bearing 5 and is movably connected with the front cover 1 of the generator. An annular sealing head 6, a fixed blind hole 7 matching with the rotating shaft 2 is provided at the center of the right side wall of the pulley 3, ...

The invention relates to safety protection technology of generators and especially relates to a dustproof and waterproof protective structure of generator bearings. The protective structure comprisesa generator front cover, a rotating shaft and a belt pulley; a driving hole which is matched with the rotating shaft is opened at a center position inside the generator front cover; a ball bearing isclamped and fixed inside the driving hole. According to the dustproof and waterproof protective structure of generator bearings of the invention, by means of an integral structure sealing head installed at a left side of the generator front cover and a sealing groove which is installed at a corresponding position at right side of the belt pulley; by using the guide chute on the inner wall of the outer side of the seal groove to separate the external impurities and the helical guide surface on the inner wall of the seal groove to separate the internal impurities, the sealing and safety of the connection end of the whole generator are greatly improved; early failure of bearings is avoided and the use service life of bearings is increased and the reliability of generators is increased.
Description
technical field [0001] The invention relates to the technical field of generator safety protection, in particular to a dustproof and waterproof protection structure for generator bearings. Background technique [0002] In order to protect the internal safety of the generator, the exterior of the generator is equipped with a casing and an end cover. The joint between the pulley and the end cover of the old structure generator is open, and water and dust will enter the inside of the bearing during use. , leading to early failure of the bearing. The early failure of the bearing cannot be completely avoided only by the sealing of the bearing itself. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved generator bearing dustproof and waterproof protection structure is provided to solve the problem that the joint between the pulley and ...
