Embodiment Construction

[0062] In the following, it will be Figure 1 to Figure 3 Preferred embodiments of the present invention are described.

[0063] The shoe roller head (base) structure according to the present embodiment has a base 1 including a shaft hole 11 . The shaft hole 11 accommodates the journal 3 of the shoe roller head 9 . It should be noted that in figure 1 , the shoe roller head 9 is indicated by a dashed line.

[0064] The cross section of the shaft hole 11 is an octagonal shape. The journal 3 , which is itself circular, has a thickening 32 having an octagonal shape, which corresponds approximately to the octagonal shape of the shaft hole 11 . In the following, where appropriate, for the sake of convenience, the surface of the thickened portion is simply referred to as the surface of the journal.

[0065] Among the eight surfaces of the shaft hole 11, the machining accuracy of one surface 11a at the lowest position in the figure (hereinafter also referred to as the six o'cloc...

Abstract

A shoe roller base structure includes a base (1) having a shaft hole (11) and a journal (3) accommodated in the shaft hole (11). The cross section of the shaft hole (11) is polygonal. At least one surface (11a) of the shaft hole (11) is a torque surface. Here, the torque surface refers to a surface that can be machined more accurately than one or more of the remaining reference surfaces of the shaft hole (11) and absorb torque. The cross section of the journal (3) is a polygonal shape corresponding to the polygonal shape of the shaft hole (11). Each surface of the journal (3) corresponding to one of the at least one torque surface of the shaft hole (11) abuts the corresponding torque surface of the shaft hole (11). The numbers of torque surfaces of the shaft hole (11) and of the journal (3) are respectively lower than the sum of the surfaces of the shaft hole (11) and the surface of the journal (3).

Description

technical field [0001] The present invention relates to a shoe roll pedestal (pedestal) structure, and more particularly to an improved shoe roll pedestal structure with precise alignment of the rollers with the pedestal. This shoe roll base structure is a subassembly of a new shoe roll end module developed by the applicant but not yet disclosed. Background technique [0002] It is known from the prior art that a pressure stub (stub) is accommodated in the circular hole of the rocker bearing, which is arranged in the base. In order to prevent misalignment of the shoe rolls, the contact surface must be machined to a certain precision using turning machining. Although small gaps are unavoidable in manufacturing, these gaps can affect the accuracy of roll alignment. [0003] The prior art document EP 1820900 A1 teaches the use of pin members as torque supports. The pin member enters the support shaft through the base and the rocker bearing ring. Thereby the torque can be ab...
