Intelligent constant-filling hydraulic coupling

Abstract

The invention discloses an intelligent constant-filling hydraulic coupling. The working conditions of the intelligent constant-filling hydraulic coupling can be detected online in real time, and the intelligent constant-filling hydraulic coupling is convenient to disassemble or assemble. The intelligent constant-filling hydraulic coupling is characterized in that a pressure sensor, a temperature sensor and a driving end rotating speed sensor are arranged on a shell or a pump wheel; a driven end rotating speed sensor is arranged on a main shaft; sensor signals are collected and sent into corresponding micro-control units (MCUs) to be processed, are then transmitted through a wireless emission module, and are received by a wireless receiving module and then transmitted to an electronic control unit, so that real-time detection of the working condition of the hydraulic coupling is realized; and meanwhile, an expansion sleeve is arranged in a main shaft assembly end inner hole, a shaft hole is formed in the expansion sleeve, the outer surface of the expansion sleeve is connected with the inner surface of the main shaft assembly end inner hole through a sectional wedge-shaped conical surface, an axial through groove is formed in the expansion sleeve, one end of the expansion sleeve is connected with a locking nut, and the locking nut is connected with the main shaft assembly end inner hole through threads. By means of the intelligent constant-filling hydraulic coupling, the working condition of the hydraulic coupling can be detected online in real time, so that the intelligent management of equipment can be realized by a customer. Moreover, a connecting device enables the hydraulic coupling to be disassembled or assembled conveniently.

Description

technical field [0001] The present invention relates to a hydraulic coupling, in particular to a constant filling type hydraulic coupling, in particular to a constant filling type hydraulic coupling which can detect the working condition of the constant filling type on-line and in real time and is convenient for the disassembly or installation of the hydraulic coupling Intelligent fixed-fill hydraulic coupling. Background technique [0002] Fixed filling type (torque-limiting type, common type) hydraulic couplings are widely used because of their characteristics that other transmission methods do not have. Since the fixed-fill hydraulic coupling is a closed transmission element, it is impossible to adjust its liquid filling volume during its operation. When the fixed-fill hydraulic coupling encounters severe overload of the working machine, it will reduce the output speed until it stalls (output zero transmission speed) to realize torque limit protection for the entire tran...

Problems solved by technology

As the ultimate overload protection of the fixed-fill hydraulic coupling for the whole machine, whether it is spraying liquid through the safety plug or using the anti-blowout safety plug, there are deficiencies: when the fusible safety plug is used for liquid spraying protection, the sprayed working medium The site environment is polluted to some extent, and the high-temperature liquid may cause harm to the surrounding personnel. To restore the operation of the hydraulic coupling, it is necessary to refill the fluid and replace the safety plug, which is troublesome to operate; however, the use of the anti-blowout safety plug can avoid the ejection of the working medium , but because of its low operating temperature setting (the anti-blowout safety plug must be used in conjunction with the fusible safety plug, the action temperature of the anti-blowout safety plug is much lower than the melt blown temperature of the fusible safety plug), which will make the overload capacity of the working machine It is greatly reduced, and the anti-blowout safety plug must also be replaced to restore the operation of the hydraulic coupling

However, there are firstly that the machining accuracy of the thread of the screw sleeve is high, the processing is difficult, and the quality is difficult to guarantee. The thread fit precision of the screw sleeve and the dismounting screw is not high, the frictional resistance is large, and the strength of the thread is not enough, which may easily lead to thread damage; the second is disassembly. Inconvenient, in order to fix the motor shaft or reducer shaft, you need to remove the motor fan guard first, and then remove the fan blades

[0005] When there is no screw sleeve or the screw sleeve is damaged, the old hydraulic coupling cannot be removed, it can only be damaged and disassembled, and cannot be inspected and repaired, which not only causes certain economic losses, but more seriously delays normal production
