Problems solved by technology

[0003] At present, in the actual use of hydraulic motors, a certain amount of noise will be generated, which will bring some discomfort to the user. However, the existing hydraulic motor body shell is not equipped with a corresponding noise reduction mechanism. Therefore, we propose a nodular cast iron Hydraulic motor housing

Abstract

The invention discloses a nodular cast iron hydraulic motor body shell which comprises a noise reduction cover, a motor body shell body is arranged in the noise reduction cover, the noise reduction cover is formed by splicing two half cover bodies through a connecting mechanism, and the noise reduction cover is installed on the outer side of the motor body shell body through an installation mechanism; each half cover body is composed of a shell, an external sound absorption layer located on the inner side of the shell, a middle sound insulation layer located on the inner side of the external sound absorption layer and an internal sound absorption layer located on the inner side of the middle sound insulation layer. The middle sound insulation layer is composed of an outer sound insulation layer close to the external sound absorption layer, an inner sound insulation layer located on the inner side of the outer sound insulation layer and a filling layer located between the outer sound insulation layer and the inner sound insulation layer, and the outer sound insulation layer is connected with the inner sound insulation layer through a connecting semi-ring. The noise reduction cover is arranged on the motor body shell so that noise generated by the motor can be isolated and absorbed, and meanwhile the whole noise reduction cover is easy to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of hydraulic motors, in particular to a ductile iron hydraulic motor casing. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and rotational speed) of its output shaft. Liquid is the medium that transmits force and motion. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, marine machinery, petrochemical, port machinery, etc. [0003] At present, a certain amount of noise will be generated in the actual use of hydraulic motors, which will bring a certain sense of discomfort to users. However, the existing hydraulic motor casings do not have a corresponding noise reduction mechanism. For this...
