Gear Transmission Device with Overspeed Circular Displacement Output Function

Abstract

The invention proposes a gear transmission device having an overspeed circumferential displacement output function. The device improves a main shaft on the structure of a traditional gear transmission device, is added with a displacement output mechanism, and mainly consists of a spline shaft, a transmission shaft, a straight gear, an oil stop shaft part, a speed limiting block, a parking sleeve, an output rod, a box body, a box cover and the like; the rotating speed is input by using the spline shaft; on the one hand, the longitudinal rotating speed output is generated through the bevel gear engagement; and on the other hand, an oil stop shaft in the oil stop shaft part rotates through first-grade gear transmission; a heavy block mounted on the oil stop shaft is deviated from the oil stop shaft under the effect of centrifugal force; and when the designed rotating speed is exceeded, the speed limiting block is ejected, and rotates to drive the parking sleeve and the output rod to generate the displacement output in the circumferential direction. The device can serve as a diesel engine accessory, not only can serve as a transmission device, but also can serve as an action generation mechanism of a galloping protection device.

Description

Technical field [0001] The invention belongs to the field of diesel engines, and particularly relates to a gear transmission device used as an accessory of a diesel engine. Background technique [0002] Gear transmissions are various gear mechanisms that mesh with each other or connect with each other. [0003] Gear transmission devices are widely used in industries such as automobiles, ships, power stations, and construction machinery, and generally play the role of speed reduction and torque transmission. Gear transmissions usually do not have the function of transmitting speed and realizing displacement output at a certain speed. [0004] As a diesel engine accessory, the existing technology is also used for ordinary speed reduction and transmission torque. Diesel engines also need accessories for transmitting speed and displacement output. For example, it is used as the action generating mechanism of the flying protection device. The existing diesel engines often In addition, t...

Problems solved by technology

[0004] As an accessory of a diesel engine, the gear transmission device is also used for ordinary deceleration and transmission of torque in the prior art, and the diesel engine also needs accessories for transmitting speed and displacement output, such as an action generating mechanism for a runaway protection device. Existing diesel engines are often It is another separate design of accessories to realize these functions, which makes the machine have many accessories and complex structure
