Flying cone type mechanical full speed variable speed controller for diesel engine

Abstract

The invention provides a flying cone type mechanical full speed variable speed controller for a diesel engine. The speed controller mainly comprises a flying cone power conversion device, a buffer device and a full speed variable device and is characterized in that the speed controller is in a full speed variable manner. Through a flying cone with the sector-shaped section and the 45-degree included angle between the chord length and the side edge, the aim that the radial feeding amount of the flying cone and the axial output amount of the flying cone are the same is achieved, and it is ensured that a thrust inclined disc moves stably; through the buffer device behind the thrust inclined disc, the side effect of vibration on a plunger is eliminated; through a low-speed limiting plate, low-speed starting is controlled, and it is ensured that the plunger accurately returns to be in the initial state; and through a movable high-speed limiting plate, the high speed variable adjusting function of the speed controller is achieved.

Description

technical field [0001] The invention relates to a flying cone type mechanical variable full-speed governor for diesel engines, in particular to a flying cone with a fan-shaped cross section and a 45° included angle between the chord length and the side to realize the radial feed of the flying cone and the The axial output is the same to ensure the smooth movement of the thrust swashplate; through the buffer device behind the thrust swashplate, the adverse effect of vibration on the plunger is eliminated; through the low-speed limiting plate, the low-speed start is controlled and the plunger is accurately returned to the initial state; through The movable high-speed limiting plate realizes the variable-speed adjustment function of the governor, and belongs to the technical research and development field of the mechanical centrifugal governor. Background technique [0002] The function of the governor is to automatically adjust the fuel supply of the fuel injection pump accord...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems that the lowest and highest speeds of the existing mechanical centrifugal speed governors are generally fixed values, which brings inconvenience to the use under different working conditions, and some bad factors affect the oil supply of the plunger, etc., and provides A flying cone mechanical variable full-speed governor for diesel engines that can effectively solve the above problems
