Electromagnetic performer

Abstract

The invention discloses an electromagnetic performer, comprising a shell (100) provided with an inner cavity, a back end cover (600) which is matched with an assembly hole (121) on a back end surface (120) of the shell (100), and a ratio electromagnet (200) and a transmission rod (400) which are mounted inside the shell (100), wherein an output shaft (201) of the ratio electromagnet (200) is connected with a swing arm device (300) in a contact way; the swing arm device (300) is movably connected with the transmission rod (400); and a spring (500) is arranged between a rod body of the transmission rod (400) and a front end surface (110) of the shell (100). The electromagnetic performer provided by the invention is simple in structure and good in sealing property and is capable of removing transmission gaps.

Description

technical field [0001] The invention relates to an electromagnetic actuator, in particular to an electromagnetic actuator for controlling the fuel injection quantity of a diesel engine. Background technique [0002] In the prior art, the fuel injection quantity of the diesel engine is controlled by an electronic speed regulation actuator. Among them, the electronic governor includes a circuit control board and an electromagnetic actuator. The electromagnetic actuator is an executive component that controls the fuel injection quantity of the diesel engine. The electromagnetic actuator of the existing structure includes a housing composed of a front end face, a rear end face, and a plurality of side end faces; the housing is provided with an inner cavity and an oil pressure cavity, and a proportional electromagnet is installed in the inner cavity, and the oil pressure A transmission rod is installed in the cavity, and the transmission rod and the proportional electromagnet a...

AI Technical Summary

Problems solved by technology

[0005] 1) The shell is combined, which makes the structure of the electromagnetic actuator more complicated and the sealing performance is poor;

[0006] 2) The housing is provided with an oil pressure chamber and an inner chamber respectively, and the seal between the oil pressure chamber and the inner chamber must be realized by a sealing assembly, which makes the structure of the electromagnetic actuator more complicated;

[0007] 3) In the rotating device, rolling bearings are installed in many places, and the rolling bearings are fixed by pins, so there is a connection gap; since there is no return device between the slip ring and the rotating device, and between the rotating device and the transmission rod, the rotating device is in the When rotating, there will be a rotation gap, and the electromagnetic actuator will have a larger transmission gap.
