the utility model provides a universal joint with a dustproof sleeve, which comprises a cross shaft and two transmission shaft forks, wherein the cross shaft is connected between the transmission shaft forks; the dustproof cover is positioned at the connecting position of the two transmission shaft forks, and is sleeved on the outer side of the cross shaft; the two ends of the dust cover are rotatably connected to the transmission shaft fork.
The transmission shaft fork comprises a fork lug and a shaft lever, wherein the cross shaft is connected to the fork lug, and the shaft lever is connected to one end, far away from the cross shaft, of the fork lug; the dust cover is rotatably connected to the shaft lever.
The preferable technical scheme of the utility model is that a bearing is sleeved on the shaft rod, a mounting ring is fixedly arranged on the outer ring of the bearing, and the dustproof cover port is detachably arranged on the mounting ring.
The preferable technical scheme of the utility model is that a plurality of fixing holes are arranged on the mounting ring;
the dust cover is characterized in that connecting rings are fixedly arranged at two ends of the dust cover, and are sleeved on the outer side of the mounting ring and fixedly connected with the fixing holes through bolts.
The utility model has the preferable technical scheme that the middle part of the dust cover is provided with a supporting ring.
The utility model is preferably characterized in that the dust cover is made of natural rubber material.
The beneficial effects of the utility model are as follows:
according to the universal joint with the dust cover, the universal joint and the dust cover are connected and separated in a rotating mode, and the dust cover is connected and fixed through the external device under the condition that the universal joint runs at a high speed, so that extrusion abrasion and high-speed expansion damage factors of the universal joint and the dust cover are avoided under a large angle after loading, and the service lives of the universal joint and the dust cover are greatly prolonged.
