Adjustable revolution speed sensor support

Abstract

The invention belongs to the technical field of machinery, and relates to an adjustable revolution speed sensor support. The adjustable revolution speed sensor support is provided with a fixed bottomplate used for being fixed on a front end cover of a diesel engine; notches for indicating the installation direction are formed in two ends of the end face on one side in the width direction of the fixed bottom plate; a plurality of sensor support bodies are fixed on the fixed bottom plate and form an arc; a threaded through hole for mounting a sensor is formed in the center of each sensor support body; the sensor is a structure capable of freely moving along the axial direction of the threaded through holes; a circular smooth hole for being matched with a connecting bolt is machined in eachsensor support body; the top of each circular smooth hole is a circular counter bore matched with the end of each connecting bolt; and a mounting bolt is of a structure capable of freely moving up anddown along the axial direction of each circular smooth hole. According to the adjustable revolution speed sensor support, the problem that the position deviation of the sensor support bodies is caused by large thermal deformation because of integral welding is solved.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an adjustable rotating speed sensor bracket. Background technique [0002] The speed signal of the diesel engine is mainly collected by the speed sensor, and the speed sensor needs to be fixed with the speed sensor bracket; in the design process, it is necessary to ensure the positioning accuracy and reliability of the bracket, and the position and quantity can be adjusted at the same time. [0003] A certain type of diesel engine is designed to install the speed measuring gear at the free end, and the speed sensor bracket is installed on the front cover. It is necessary to use the speed sensor bracket to fix the speed sensor and align it with the speed measuring gear. Due to the compact structure of the front end of the front cover, it is necessary to avoid the fresh water pump, Seawater pumps and high-pressure oil pipes cannot be directly integrally welded with conventional desi...

Problems solved by technology

[0003] A certain type of diesel engine is designed to install the speed measuring gear at the free end, and the speed sensor bracket is installed on the front cover. It is necessary to use the speed sensor bracket to fix the speed sensor and align it with the speed measuring gear. Due to the compact structure of the front end of the front cover, it is necessary to avoid the fresh water pump, Seawater pumps and high-pressure oil pipes cannot be directly integrally welded with conventional designs. Conventional integral welding is to weld the fixed bottom plate and the main body of the bracket as a whole. Due to the compact space at the front end of the front end cover, if integral welding is used, the bracket position, quantity, applicable The specification of the speed sensor cannot be adjusted, the installation process is poor, and the welding thermal deformation is large, resulting in inaccurate positioning
