Description

Power mechanism of wheel rail lubricating device

The technical field is as follows:

the parts with mechanical motion need to be lubricated and different lubricating materials have different feeding modes. Typically, lubricating oil and grease of lower consistency may be pumped to transport lubricant through a conduit to the lubrication site. Greases of higher consistency have good retention properties and are usually added directly to the lubrication sites. For solid lubricating materials, special conveying means are required to maintain a continuous supply to the lubrication sites.

Background art:

in the field of wheel rail lubrication of rail transit, due to the particularity of the lubricated part, the conveying position of a lubricant is required to be accurate, the lubricant cannot be thrown and sputtered, and a solid lubrication mode is generally adopted. At present, various conveying modes basically adopt an elastic conveying device, constant thrust is applied to the rear part of a lubricating rod, the lubricating rod is pushed to be in contact with a lubricated part, and a lubricating material is coated on the surface of the lubricated part. The lubricating rod of the conveying mode is always in contact with a lubricated part, and the conveying amount cannot be controlled, so that the lubricating rod can only be used in the field of wheel rim lubrication.

Chinese patent ZL202022038132.7 describes a lubricant block driving mechanism, which can be combined with a "lubricant block driving mechanism" to form a wheel-rail lubrication device.
