Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 shown;

[0023] A balance lever structure for adjusting throttle lever torque according to an embodiment of the present invention, the structure includes:

[0024] The camshaft 1 that is rotationally connected to the regulator housing (not shown) at both ends, the camshaft 1 and the regulator housing are connected by ball bearings, and the camshaft 1 and the throttle lever (not shown) are connected by internal and external splines , the internal and external splines are installed in the form of staggered teeth, which eliminates idle travel and ensures that the throttle lever and camshaft 1 rotate synchronously;

[0025] Control lever 2, the control lever 2 is arranged on the upper side of the camshaft 1, and fits the lift pr...

Abstract

The invention discloses a balance lever structure for adjusting the torque of a throttle lever, which comprises a cam shaft with two ends rotatably connected with a regulator shell, and the cam shaft is connected with the throttle lever through an internal spline and an external spline; the control lever is arranged on the upper side of the cam shaft and attached to the lift profile of the cam shaft. The balance lever is arranged on the lower side of the cam shaft and attached to the balance molded surface of the cam shaft, and the balance lever and the control lever are arranged in parallel. The torque of the throttle lever can be effectively adjusted, abrasion of parts is reduced, the service life of mechanical parts is prolonged, and reliability of the mechanical parts is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical hydraulic fuel regulator equipment, in particular to a balance lever structure for adjusting the torque of an throttle lever. Background technique [0002] The aero-engine fuel regulator belongs to a complex mechanical-hydraulic system, which is composed of multiple components that are coupled with each other, and is an important part of the aero-engine. On the one hand, the fuel regulator is used as the actuator of the main control amount of fuel, and on the other hand, it is used as the mechanical hydraulic control backup of the digital control system of the aeroengine. [0003] The throttle lever structure in the existing mechanical hydraulic fuel regulator generally has the problem that the torque is greater than the required value, which is not conducive to the operation of the mechanical part, but also causes serious wear and tear on the camshaft, bearings and other parts, which is very h...
