Heavy loading shaft push device for hole

Abstract

The invention discloses a heavy loading shaft push device for a hole. The device comprises a push shaft which is arranged in an outer shaft; a bearing push plate which is fixed on the inner wall of the outer shaft is radially (axially) arranged on the shaft end of the push shaft; at least two shearing push plates which are radially embedded into a groove of the inner wall of the outer shaft are arranged on the outer side of the bearing push plate, and the shearing push plates are fixedly connected with the bearing push plate through bolts; a left shearing push plate and a right shearing push plate are symmetrically and radially embedded into an annular groove of the corresponding inner wall of the outer shaft; and the bolts are uniformly and circumferentially distributed on the outer sides of the shearing push plates and connect the shearing push plates and the bearing push plate. The heavy loading shaft push device has the characteristics of small design limitation and huge bearing and the like, and is easy to process and assemble and works reliably.

Description

technical field [0001] The invention relates to an axial propulsion device capable of bearing huge axial loads, in particular, it is applicable to mechanical equipment with heavy loads and very high reliability requirements, such as ships, metallurgy, wind power and other industries. Background technique [0002] The traditional axial bearing methods mainly include the following two types: the first one is the bearing bearing of the retaining ring for the hole, see figure 1 As shown, it includes a thrust shaft 12 placed in the outer shaft 11, a thrust plate 13 radially arranged in the outer shaft 11 is arranged at the axial end of the thrust shaft 12, and a hole is adopted on the outside of the thrust plate 13 It is fixed on the inner wall of the outer shaft 11 with a circlip 14 . [0003] The working principle of the above-mentioned circlip bearing for the hole is: the thrust shaft 12 generates an axial force P, passes through the thrust plate 13, and then transmits the ...

AI Technical Summary

Problems solved by technology

[0005] The working principle of the end pressure plate bolt bearing thrust is: the thrust shaft 12 generates an axial force P, passes through the thrust plate 13, and then transmits the force to the thrust bolt 16 on the shaft end pressure plate 15; the bolt 16 bears the axial force, Due to the limitation of installation space, the size and quantity of bolts 16 will be limited, so the design safety factor is lower than that of the circlip for holes; at the same time, bolts are easily affected by partial loads, resulting in overloading of a single bolt until failure
