Disclosed is a composite seal for a rzeppa universal joint. The composite seal for the rzeppa universal joint is used for transmission systems of mechanical equipment such as vehicles. The inner diameter of the large end of an inner seal is matched with the diameter of an annular groove in the outer circle of an outer sleeve of the rzeppa universal joint, and the large end of the inner seal is clamped in the annular groove. The inner diameter of the small end of the inner seal is matched with the diameter of the outer circle of a spline shaft of the rzeppa universal joint, and the small end of the inner seal is closely attached to the outer circle of the spline shaft. A dust cover is mounted outside the inner seal. The large end of the inner seal and the large end of the dust cover are fixed to the outer circle of the outer sleeve through a large hoop together. The small end of the dust cover is matched with an annular groove in the outer circle of the spline shaft, clamped in the annular groove and fixed to the outer circle of the spline shaft through a small hoop. The inner seal is in a shape of a bent curve structure. The small end of the inner seal is of a flexible lip structure. The inner seal can seal grease separately; when the dust cover is damaged, it can be guaranteed that the grease does not leak all the time; the lubricating grease can be prevented from flowing towards the interior of the dust cover in work; and it is guaranteed that the grease inside the rzeppa universal joint is centralized in a work lubricating area, thus, the lubricating efficiency and effectiveness are improved, and the requirement of the rzeppa universal joint for the large extension and retraction amount is met.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a compound seal for ball cage universal joints used in transmission systems of mechanical equipment such as vehicles. Background technique [0002] The existing seal of the ball cage universal joint is a corrugated dustproof cover, one end of which is fixed on the jacket of the ball cage universal joint, and the other end is fixed on the spline shaft of the universal joint. When the ball cage universal joint rotates, this dust cover can preserve grease and prevent foreign matter such as external dust from entering the interior of the universal joint. However, under harsh conditions of use, the dust cover is prone to breakage and grease leakage, especially when working in the field, this problem is more prominent. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a compou...
