Problems solved by technology

[0002] The current fan is easily corroded in the acid-base gas environment, which not only affects the service life of the fan, but also affects the output rate of industrial products. Therefore, the design of the anti-corrosion fan is basically connected with the bearing and the fan blade. This has better anti-corrosion performance, but the bearings with the same diameter have serious oil leakage and troublesome installation

Embodiment Construction

[0011] Describe in detail below in conjunction with accompanying drawing:

[0012] In the fan structure, there are two bearings (3) on the fan rotor (1), and there is a labyrinth oil passage (2) in front of the bearings to supply oil to ensure the normal operation of the bearings and oil seals, so that the rotor and bearings can A relatively good closed environment is formed to ensure that the bearings and internal units are not corroded.

[0013] In specific implementation, the oil circuit can also adopt a multi-curve reciprocating structure to ensure oil recovery and circulation.

[0014] In addition, the two bearings can be designed into a structure with little difference in size to increase the strength of the mechanical load and avoid damage to the life of the fan due to the bottleneck principle.

Abstract

The invention provides a bearing seat special for ventilator. Two bearings fix the blade of the ventilator. The oil supply circuit of the bearing is of labyrinth structure. One bearing is big and the other is small, the end bearing is of small diameter and the middle bearing is of large diameter. As adopting large, small two bearings, mounting can be done at one side, and the labyrinth structure of the ventilator ensures the oil supply to bearing more sufficient. Advantages: avoided over heated of machine oil, long service life and convenient mounting.

Description

technical field [0001] The invention relates to a bearing seat, in particular to a special bearing seat for a ventilator. Background technique [0002] The current ventilator is easily corroded in the acid-base gas environment, which not only affects the service life of the ventilator, but also affects the output rate of industrial products. Therefore, in the design of the anti-corrosion ventilator, the bearing and the fan blade are basically connected as a whole. This has better anti-corrosion performance, but the bearings with the same diameter have the problems of serious oil leakage and troublesome installation. Contents of the invention [0003] The invention provides a special bearing seat for a ventilator which is convenient to install and has less oil leakage. [0004] For realizing the above object, technical scheme of the present invention is: [0005] A special bearing housing for fans, with two bearings to fix the fans of the fan, characterized in that the be...
