Problems solved by technology

However, whether it is a mechanical transmission or an electromagnetic transmission, without considering the loss, the maximum theoretical output speed is the speed of the transmission device such as a pulley. When the input power of the power device is constant, it cannot be used for situations with higher requirements on the speed. Satisfy

specific Embodiment approach 2

[0026] The difference between the overspeed transmission device of the present invention and Embodiment 1 is that the diameter d3 of the second driven wheel 3 is larger than the diameter d2 of the first driven wheel 2 , and the diameter d1 of the driving wheel 1 is greater than or equal to the diameter d4 of the third driven wheel 4 .

specific Embodiment approach 3

[0027] The difference between the overspeed transmission device of the present invention and Embodiments 1 and 2 is that the diameter d3 of the second driven wheel 3 is set to be greater than the diameter d2 of the first driven wheel 2, and the diameter d1 of the driving wheel 1 is greater than or equal to the diameter d4 of the third driven wheel 4 , and the diameter d4 of the third driven wheel 4 is greater than the diameter d3 of the second driven wheel 3 .

[0028] For the overspeed transmission of the present invention, there are many ways of setting the diameter relationship of the driving wheel 1, the first driven wheel 2, the second driven wheel 3 and the third driven wheel 4, as long as it is adjusted according to the transmission ratio formula di / dk=nk / ni design, the angular velocity of the third driven wheel 4 can be greater than the angular velocity of the driving wheel 1.

specific Embodiment approach 4

[0029] The difference between the overspeed transmission device of the present invention and Embodiments 1, 2, and 3 is that the driving wheel 1, the first driven wheel 2, the second driven wheel 3 and the third driven wheel 4 are all sprockets, and the driving wheel 1 and the first driven wheel Between the driving wheels 2 and between the second driven wheel 3 and the third driven wheel 4 are driven by chains respectively.

Abstract

The invention relates to an overdrive device and an electromagnetic fan clutch with the same. The purpose of the invention is to provide the overdrive device under the certain input power of a power unit. The overdrive device comprises a driving gear, a third driven gear, a controller I, a first driven gear and a second driven gear, the driving gear and the third driven gear are rotatably connected onto a spindle, the controller I transmits the power of the third driven gear to the spindle, and the first driven gear and the second driven gear are fixedly connected onto an auxiliary shaft. Consequently, the angular velocity of the third driven gear is higher than the angular velocity of the driving gear.

Description

technical field [0001] The invention relates to a transmission device, in particular to a device capable of forming overspeed transmission and an electromagnetic fan clutch with the device. Background technique [0002] The transmission device is an intermediate device that transmits the power of the power device to the working mechanism. It can be transmitted through the cooperation of the mechanical structure or through the electromagnetic device. At the same time, it can also realize variable speed adjustment, such as the existing electromagnetic fan clutch. The electromagnetic transmission device is like this: the pulley is set on the main shaft, the iron core with the coil is embedded in the center hole of the pulley, the permanent magnet fixed disc is set on the main shaft, and a suction disc is set between the permanent magnet fixed disc and the pulley. The suction disk is fixedly connected with the permanent magnet fixed disk through the elastic piece, the pulley rot...
