Problems solved by technology

The traditional rudder shaft adopts the fixed structure of the snap ring, the installation process is complicated, and requires a large installation space, and repeated disassembly reduces the positioning accuracy of the rudder installation
Due to the tight installation space of small rudders and the limited installation space of rudder shafts, traditional snap rings cannot meet the demand
In addition, the ring groove on the rudder shaft will reduce the strength of the rudder shaft and affect the service life of the rudder shaft

Embodiment Construction

[0028] like figure 1 As shown, the present invention provides a small rudder cabin installation structure that is convenient to disassemble, including rudder blade 1, rudder shaft 2, housing 3, rotating grid ring 4, O-shaped sealing ring 5, lubricating gasket 7, rudder shaft Set 8, countersunk head screw 9 and steering gear.

[0029] There are multiple rudder blades, and they are evenly distributed on the outer side of the shell in the circumferential direction, and are used to control the overall flight depth, heading and roll. Each rudder blade is driven by the steering gear, and the rudder shaft transmits torque to drive it to rotate, and all the steering gears are installed inside the housing. The lower end of the rudder shaft is connected with the rudder blade, and the rudder shaft and the rudder blade are integrally processed. The upper end of the rudder shaft passes through the shell respectively, and is connected with the rudder shaft sleeve after lubricating the gas...

Abstract

The invention discloses a convenient-to-disassemble mounting structure in a small rudder cabin. The convenient-to-disassemble mounting structure comprises a rudder blade, a rudder shaft, a shell, a lubricating gasket, a rudder shaft sleeve, a steering engine, a rotating Glyd ring and an O-shaped sealing ring, wherein a lower end surface of the rudder shaft is fixedly connected with the rudder blade and sequentially penetrates through the shell, the lubricating gasket and the rudder shaft sleeve from bottom to top, the rudder blade is tightly attached to the shell, a lubricating and sealing ring structure is installed on the rudder shaft and matched with a rudder shaft hole and a sealing groove in the shell, lubricating and sealing of the rudder shaft are guaranteed, the lubricating gasketis located between the rudder shaft sleeve and the shell and used for reducing friction between the rudder shaft sleeve and the shell, a polygonal prism is arranged at a tail end of the rudder shaft and matched with a polygonal inner hole of the rudder shaft sleeve, the rudder shaft sleeve and the rudder shaft are fixed through sunk screws, the diameter of the rudder shaft sleeve is larger than that of the rudder shaft hole in the shell, and the rudder shaft is prevented from disengaging from the shell. The small-sized rudder cabin inner mounting structure is advantaged in that the rudder shaft can be quickly disassembled and assembled in a narrow space, positioning is accurate, and stability and strength reliability in the use process are ensured.

Description

technical field [0001] The invention relates to a conveniently detachable installation structure in a small rudder compartment, which belongs to the field of mechanical technology. Background technique [0002] The rudder shaft is a transmission device that connects the rudder blade with the steering gear drive mechanism and transmits torque. The traditional rudder shaft adopts the fixed structure of the snap ring, the installation process is complicated, and requires a large installation space, and repeated disassembly reduces the positioning accuracy of the rudder installation. Due to the compact installation space of the small rudder and the limited installation space of the rudder shaft, the traditional snap ring cannot meet the demand. In addition, the ring groove on the rudder shaft will reduce the strength of the rudder shaft and affect the service life of the rudder shaft. Contents of the invention [0003] The technical problem of the present invention is: to ov...
