Embodiment Construction

[0019] The structure of the external self-lubricating gear device of the present invention is set as:

[0020] see figure 1 , the big roller 1 is connected with the small roller 2 through the connecting rod 6; the lubricating wheel 3 is connected with the big roller 1 through the left pressing mechanism 4; the lubricating wheel 3 is connected through the right The pressing mechanism 5 is connected with the small roller 2 .

[0021] see figure 2 , is a three-dimensional structural diagram of the present invention, wherein the large roller 1 is fixedly connected with the driving gear 7, and the small roller 2 is connected firmly with the driven gear 8; the driving gear 7 is connected with the driven gear The gears 8 mesh with each other, and are the working parts that need to be lubricated. The lubricating wheel 3 is in contact with the large roller 1 and the small roller 2 respectively, and the friction generated during movement will scrape off the self-lubricating material,...

Abstract

The invention discloses an externally-added self-lubricating gear device. The device is composed of a pair of meshed gears, a pair of rolling wheels and a lubricating wheel made of self-lubricating materials. According to the externally-added self-lubricating gear device, the pair of rolling wheels with knurling structures formed on the surfaces are utilized, and the lubricating wheel with a leftpressing mechanism and a right pressing mechanism is combined, so that the pair of rolling wheels and the lubricating wheel are arranged in a triangular layout; the lubricating property of the self-lubricating materials is efficiently utilized, so that the lubricating requirement of the pair of meshed gears is achieved, and the self-lubricating function of gear transmission is achieved; and the defect that self-lubricating materials used for achieving conventional self-lubricating gear transmission cannot be continuously supplemented is overcome, the real-time, continuous and durable lubricating requirements of a transmission system under the severe working condition can be met, and the objectives of small weight, reliability and persistence of the gear transmission lubricating system areachieved.

Description

technical field [0001] The invention belongs to a gear self-lubricating device, in particular to an external gear self-lubricating device. Background technique [0002] Gear transmission is the most widely used transmission form in modern mechanical engineering. In order to ensure the normal operation of transmission, gear transmission lubrication becomes very important. At present, the main gear transmission lubrication methods are: liquid lubrication (such as oil injection lubrication, matrix oil storage type lubrication, etc.), solid lubrication (such as surface coating type lubrication, grease lubrication, etc.). For liquid lubrication, due to the need for oil tanks and large weight and volume, it is often used in the lubrication of high-speed gear transmission, which has high requirements for the working environment and is expensive; solid lubrication is mainly used in low-speed gear transmission, but the loss is serious during operation, and it is not easy to replace. ...
