Problems solved by technology

[0003] Generally, when the gearbox is in working condition, it will generate impact load, which will easily cause the vibration of the bearing and the bearing seat, which will lead to the damage of gear teeth, bearing cage and other components, and reduce the reliability of the transmission system.

Embodiment Construction

[0033] The terms "first", "second", "third" and so on are only used for distinguishing descriptions, and do not represent sequence numbers, nor can they be understood as indicating or implying relative importance.

[0034] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the parts are required to be absolutely horizontal or overhanging, but can allow tilting within the tolerance range. For example, "horizontal" only means that its direction is more horizontal than that of "vertical", and it does not mean that the structure must be completely horizontal, but it can allow tilt within the working tolerance range.

[0035] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "inner", "outer", "first", "second", "upper", "lower" etc. are based on the drawings. The orientation or positional relationship shown, or the orientation or positional relationship...

Abstract

The invention discloses a bearing pedestal and a rotating piece fixing structure, and relates to the technical field of machine part structures. the bearing pedestal comprises a bearing pedestal body,a cavity, a damping filler, an oil storage channel and an oil storage hole. The bearing pedestal body is provided with an installing hole for installing a bearing. The cavity is formed in the bearingpedestal body. The damping filler is arranged inside the cavity. The oil storage channel is arranged on the bearing pedestal body. The oil storage hole is formed in the inner wall of the installing hole and communicates with the oil storage channel. Due to the damping filler arranged inside the cavity, a vibration value generated during transmission of the rotating piece fixing structure can be lowered, and the transmission reliability of the rotating piece fixing structure is improved. The bearing is lubricated through lubricating oil, with which the oil storage channel is filled, so as to reduce abrasion. Meanwhile, the damping filler is cooled through the lubricating oil, the phenomenon that the damping filler is overheated is avoided, the bearing pedestal is in the dynamic hot balancestate, and therefore the transmission reliability of the rotating piece fixing structure can be improved.

Description

technical field [0001] The present application relates to the technical field of mechanical accessories, in particular, to a fixing structure for a bearing seat and a rotating part. Background technique [0002] Bearing housings are mechanical accessories used to install bearings. Bearings are generally used to support rotating parts such as gear shafts and screw screws, which can reduce the friction coefficient during the movement of rotating parts and ensure their rotation accuracy. Bearings and housings are usually used together in gearboxes. [0003] Generally, when the gearbox is in working condition, it will generate impact load, which will easily cause vibration at the bearing and bearing seat, resulting in broken teeth of the gear, damage to the bearing cage and other components, and reduces the reliability of the transmission system. Contents of the invention [0004] The purpose of the present application is to provide a bearing seat and a fixed structure of the...
