Abstract
The utility model relates to a bearing box, and particularly relates to a leak-proof ventilating cap for a bearing box. The leak-proof ventilating cap for a bearing box comprises a ventilating cap cover, a double-screw bolt and an oil deflector, wherein the ventilating cap cover is connected with the double-screw bolt, the oil deflector is disposed in the double-screw bolt and is a labyrinth-type oil deflector, the oil deflector is a circular sheet with three notches in a staggered arrangement. The leak-proof ventilating cap for a bearing box in the utility model can reduce leakage of lubricating oil, prevent environment rainwater from entering in the bearing box, reduce loss of lubricating oil, protect quality of lubricating oil, reduce bearing loss caused by deterioration of quality of lubricating oil, and reduce maintenance cost.
Description
Technical field
The utility model relates to bearing housing, relates in particular to the ventilative cap of a kind of bearing housing.
Background technique
The thin oil lubricant bearing housing all has ventilative cap, and main effect is the heat a large amount of leakages to prevent lubricant oil from expanding that produce in the diffusion device operation process.The domestic ventilative cap that generally uses is simple, can play thermolysis, but anti-rainwater and leakage of oil ability are on the weak side, and lubricant oil leaks from ventilative cap under the centrifugal action of tightening nut easily, and this is disadvantageous for the bearing safe operation that is installed in open-air position.
Summary of the invention
The utility model is intended to address the above problem, and a kind of bearing housing leakproof cap of breathing freely is provided.The utility model can reduce oil leak and prevent that the environment rainwater from entering in the bearing housing, reduces the loss and the protection quality of lubrication oil of lubricant oil, reduces the damage of bearings that causes because of lubricant oil qualitative change difference and reduces maintenance cost.
For addressing the above problem, the utility model is achieved in that
A kind of bearing housing leakproof cap of breathing freely, it comprises ventilative cap, double-screw bolt and oil deflector, described ventilative cap connects described double-screw bolt, and described oil deflector is arranged in the described double-screw bolt, it is characterized in that, described oil deflector is the mazy type oil deflector, and it is a disk with three road breach of dislocation layout.
Described a kind of bearing housing leakproof cap of breathing freely, described ventilative cap and double-screw bolt are to be threaded.
Described a kind of bearing housing leakproof cap of breathing freely, described ventilative cap and oil deflector are aluminum.
Ventilative cap of the present utility model has three parts, and wherein critical piece is oil deflector and ventilative cap, by optimal design, reduces oil leak and prevents that rainwater from infiltrating, and improves heat dissipating capacity and reduces the oil temperature.Wherein, oil deflector forms labyrinth structure, and the dislocation of three road breach disks is arranged has increased flow passage resistance force of waterproof, can prevent that the lubricant oil that sprays upward from emerging with liquid form, and the breach structure of disk guarantees that heat distributes with gas form; Oil deflector can move freely in double-screw bolt simultaneously, can be by regulating the disk gap position to reduce the leakage of oil.
Ventilative cap is connected with double-screw bolt by thread forms, is easy to dismounting.Screw thread has a plurality of through holes outward, is convenient to gas communication, enlarges flow area, improves radiating effect.Realize gas simultaneously from cap discharge down, this can prevent that extraneous rainwater from entering in the bearing housing.
The material of oil deflector and ventilative cap all adopts aluminum to do and forms, and this can prevent that parts from getting rusty, and improves the life-span.
Description of drawings
Below in conjunction with embodiment the utility model is further described:
Fig. 1 is a sectional view of the present utility model.
Embodiment
As shown in Figure 1: a kind of bearing housing leakproof cap of breathing freely, it comprises ventilative cap 1, double-screw bolt 2 and oil deflector 3, described ventilative cap 1 connects described double-screw bolt 2, described oil deflector 3 is arranged in the described double-screw bolt 2, described oil deflector 3 is the mazy type oil deflector, and it is a disk with three road breach of dislocation layout.
Described a kind of bearing housing leakproof cap of breathing freely, described ventilative cap 1 and double-screw bolt 2 are to be threaded.
Described a kind of bearing housing leakproof cap of breathing freely, described ventilative cap 1 and oil deflector 3 are aluminum.
Claims (3)
1. the ventilative cap of a bearing housing leakproof, it comprises ventilative cap, double-screw bolt and oil deflector, described ventilative cap connects described double-screw bolt, and described oil deflector is arranged in the described double-screw bolt, it is characterized in that, described oil deflector is the mazy type oil deflector, and it is a disk with three road breach of dislocation layout.
