Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a bearing assembly applied to a cantilever suspension tower includes a locking sleeve 1, a bearing seat 2, an upper flange 3, a lower flange 4 and a lock nut 5, and also includes a first tapered thrust bearing 6 (cone needle roller bearing, tapered roller bearing) and the second tapered thrust bearing 7 (tapered needle roller bearing, tapered roller bearing).

[0017] First, the first tapered thrust bearing 6 and the second tapered thrust bearing 7 are parallel and relatively sleeved on the locking sleeve 1, that is, the upper end of the first tapered thrust bearing 6 faces downward, and the second tapered thrust bearing 7 The upper end faces upward, and the two are relatively set on the locking sleeve 1; then the bearing seat 2 is sleeved outside the locking sleeve 1 and clamps the first tapered thrust bearing 6 and the second tape...

Abstract

The invention discloses a bearing assembly applied to a cantilever tower crane. The bearing assembly comprises a locking sleeve, a bearing block, an upper flange, a lower flange, a locking nut, a first conical thrust bearing and a second conical thrust bearing, wherein the first conical thrust bearing and the second conical thrust bearing are in parallel and are relatively sleeved on the locking sleeve; the bearing block is sleeved outside the locking sleeve and clamps the first conical thrust bearing and the second conical thrust bearing; the locking nut is connected with the locking sleeve and is used for locking the first conical thrust bearing and the second conical thrust bearing between the bearing block and the locking sleeve; the bearing block and the locking sleeve are clamped bythe upper flange and the lower flange from the upper side and the lower side; and the bearing block and the locking sleeve are locked between the upper flange and the lower flange by fasteners. By adopting the two conical thrust bearings, the bearing assembly has high coaxiality, favorable stability and uniformity in stress; a rotating arm cannot laterally move in the rotating process; a joint can move more freely, stably and reliably; a medical person can operate more conveniently; and the time and the physical force are saved.

Description

technical field [0001] The invention relates to a bearing assembly applied to a medical cantilever pendant. Background technique [0002] The medical pendant is a new type of auxiliary medical equipment developed in recent years for intensive care units, operating rooms and emergency rooms of hospitals to centrally solve medical gas input, power distribution, network transmission, negative pressure suction, and exhaust gas discharge devices. [0003] Various instruments are placed on the tray of the medical pendant, and the rotating arm can rotate within a certain range, which is convenient for medical staff to operate. However, due to the large load capacity, the rotating joint of the medical pendant will bear a huge partial load during work. The existing rotary joint adopts the structure of two plane thrust needle roller bearings, which can meet the load-bearing strength requirements, but because the plane thrust needle roller bearings have no restrictions in the radial di...
