Medium-and-low-speed high-efficiency continuously variable transmission

Abstract

The invention relates to the technical field of speed change equipment, in particular to a medium-and-low-speed high-efficiency continuously variable transmission. The medium-and-low-speed high-efficiency continuously variable transmission comprises a first transmission gear, a second transmission gear, a transmission belt, a supporting mechanism, a box body, an extruding mechanism, a liquid storage base, a liquid discharging mechanism and a lubricating mechanism. According to the medium-and-low-speed high-efficiency continuously variable transmission, when the transmission belt passes throughthe box body, the inner surface of the transmission belt makes contact with the outer walls of balls and drives all the balls to rotate, so that the transmission belt is supported, and the transmission belt is prevented from drooping; a sponge strip can adsorb lubricating fluid and supply the lubricating fluid to a sponge mat so that the lubricating fluid can be adhered to the balls and can be carried to the inner surface of the transmission belt, and the transmission belt can be lubricated; moreover, the liquid discharging mechanism can also be driven to rotate in the movement of the transmission belt, so that cyclic compression of the sponge strip is realized, and then the sponge strip can quickly suck the lubricating oil; and when the transmission belt is broken, a buzzer is electrified to give an alarm, then a worker can be timely reminded to know that the transmission belt is broken, and quick response can be realized.

Description

technical field [0001] The invention relates to the technical field of transmission equipment, in particular to a medium-low speed high-efficiency continuously variable transmission. Background technique [0002] The continuously variable transmission uses the drive belt and the driving and driven wheels with variable working diameters to transmit power, which can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions; the common continuously variable transmission has hydraulic Mechanical continuously variable transmission and metal belt continuously variable transmission.

[0003] The transmission belt is an important part of the transmission. Since the transmission belt works with friction for a long time, its maintenance is very important. However, there is currently a lack of better lubrication equipment for the transmission belt, which makes the friction between the transmission belt and the gears larger and generates more heat. , a large amount of wear and tear, thereby reducing the service life
