Engine Output Shaft Connecting Device and Its Application Separate Hydraulic Power Unit

Abstract

The invention discloses an engine output shaft connection device, which comprises a spacer ring, a positioning sleeve and a lengthening shaft, wherein one end of the spacer ring is fixedly arranged on a fixed box wall of a driving component or a shaft end surface of an engine, and the other end of the spacer ring is detachably connected with another component; the lengthening shaft is coaxially arranged in the spacer ring, one end of the lengthening shaft is coaxially fixedly connected with an engine output shaft or the input shaft of a driving component, and the other end of the lengthening shaft is a hollow shaft and is sheathed on the other shaft part by key connection; the positioning sleeve is coaxially arranged between the spacer ring and the lengthening shaft; the diameter of the outer ring of the positioning sleeve is equal to the internal diameter of the spacer ring; the positioning sleeve is sheathed on the lengthening shaft; the tail end part of the outer ring of the hollow shaft section of the lengthening shaft is a cone of which the diameter gradually increases; the maximum internal diameter of the positioning sleeve is not greater than the maximum diameter of the hollow shaft section of the lengthening shaft. The quick alignment of the lengthening shaft and the engine shaft is realized by the positioning sleeve, the positioning sleeve and the lengthening shaft are separated after the engine finishes being installed, equipment is free from additional power loss, and the use efficiency of various types of hydraulic construction equipment can be further improved.

Description

technical field [0001] The invention belongs to the field of engine technology and hydraulic power technology, and in particular relates to an engine output shaft connection device and a separate hydraulic power station for its application. Background technique [0002] Small industrial engines usually do not use fixed connections. An engine can usually be connected to replace different drive components for multiple purposes. During the connection setting process of the engine, a connecting shaft will be used to connect the output shaft of the engine and the input shaft of the drive components. It is difficult to install the connecting shaft in the process of connecting the engine or driving parts. During the installation process, the most important thing is the centering of the connecting shaft. The connecting shaft is usually fixedly connected to one end of the shaft part, and the other end is suspended. In this way, the axis of the connecting shaft is often not on the sam...

[0002] Small industrial engines usually do not use fixed connections. An engine can usually be connected to replace different drive components for multiple purposes. During the connection setting process of the engine, a connecting shaft will be used to connect the output shaft of the engine and the input shaft of the drive components. It is difficult to install the connecting shaft in the process of connecting the engine or driving parts. During the installation process, the most important thing is the centering of the connecting shaft. The connecting shaft is usually fixedly connected to one end of the shaft part, and the other end is suspended. In this way, the axis of the connecting shaft is often not on the same shaft axis as the shaft parts connected at both ends. Whether it is the hoisting of the engine or the lifting of the driving parts, it is time-consuming and labor-intensive. It is necessary to quickly connect the connecting shaft to one of the shaft parts. After the coaxial centering is set, the other end can quickly achieve positioning and connection assembly. If the coaxial centering is not realized during the installation process, the shaft parts will wear out during the working process of the drive components, and the power loss of the equipment will be relatively large, which will affect normal work

[0003] Taking the hydraulic power station in the process of electric power construction as an example, in the complex field construction environment, the handling of the hydraulic power station with a large weight and volume is quite difficult, especially in emergency rescue projects, where various terrain environments may appear, The handling of the hydraulic power unit has had a great impact on construction and rescue, and seriously affects the speed and progress of construction and rescue. Therefore, the engine and hydraulic power unit will be transported separately and connected and assembled at the construction site

But often in the connection and assembly process of the engine, due to limited construction conditions, the quick connection assembly of the engine is more difficult
