The invention discloses a sealing ring mounting structure of an eccentric cam. The sealing ring mounting structure comprises an eccentric cam cylinder fixedly connected to a mounting frame, wherein the eccentric cam cylinder comprises a first cylinder and a second cylinder, the outer side end face of the first cylinder is a T-shaped end face, and a sealing cover plate is arranged at the joint between the first cylinder and the second cylinder; the periphery of the first cylinder is sleeved with a needle roller bearing, and the needle roller bearing is limited between the T-shaped end face andthe sealing cover plate; the periphery of the needle roller bearing is sleeved with a rotating wheel; the rotating wheel is connected with an external rotating driving mechanism; and the two ends of the rotating wheel are respectively provided with a first sealing clamping groove and a second sealing clamping groove, meanwhile, a first sealing ring and a second sealing ring are embedded in the first sealing clamping groove and the second sealing clamping groove, and the needle roller bearing is packaged between the eccentric cam cylinder and the rotating wheel. Under the effect of realizing eccentric oscillation rotation, the adopted mounting structure is simple, the occupied volume is small, the bearing seal for the eccentric cam is well realized, and the leakage of bearing lubricating oil is avoided.
Description
technical field [0001] The invention belongs to a sealing technology, in particular to a sealing ring installation structure of an eccentric cam. Background technique [0002] Eccentric cams are widely used in vibration follower products, because good lubrication is required to ensure a long service life. Most of the existing eccentric cam vibrators are used in the construction industry, the structure occupies a large volume, and there are many installation structures, so it is usually not required to have a good oil sealing effect inside. However, the applicant wishes to develop and improve a new eccentric cam vibrator structure and apply it to the oscillation module of some precision equipment, therefore, it needs to have good oil sealing performance. [0003] Therefore, the applicant wishes to seek a sealing ring installation structure of an eccentric cam to solve the technical problems existing in the prior art. Contents of the invention [0004] In view of this, the...
