Embodiment Construction

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Such as Figure 1-3 As shown, the eccentric positioning idler includes an idler (01), an annular support (02), a support body (03), a fixing member (04) and an idler shaft (05); one end of the section of the idler shaft (05) It is a ring-shaped boss, the ring-shaped boss is provided with the ring support (02) and the support body (03) in sequence along the axial direction; the idler shaft (05) is penetrated with the axial parallel The fixing piece (04); the supporting body (03) is sleeved on one end of the fixing piece (04); the longitudinal section of the other end of the fixing piece (04) is opposite to the supporting body (03) Matching convex ring; the outer side of the annular support bearing (02) is sheathed with the idler (01). The top protrusion of the support body (03) is provided with an idler shaft accommodating hole ...

Abstract

The invention provides an eccentric locating idler wheel shaft. The eccentric locating idler wheel shaft comprises an idler wheel, an annular supporting piece, a supporting body, a fixed part and an idler wheel shaft. An annular boss is arranged at one end of the section of the idler wheel shaft, and the annular supporting piece and the supporting body are arranged on the annular boss in the axial direction in sequence. The fixed part which is parallel to the idler wheel shaft in the axial direction is arranged in the idler wheel shaft in a penetrating mode. The supporting body sleeves one end of the fixed part, and the longitudinal section of the other end of the fixed part is a convex ring which is matched with the supporting body. The idler wheel sleeves an annular supporting bearing. An eccentric hole idler wheel shaft locating device is compact in structure and flexible in layout, can prevent the idler wheel shaft from conducting micro-rotation under the action of periodic rolling force of the bearing, and is convenient to disassemble and assemble.

Description

Technical field [0001] The invention relates to an idler shaft, in particular to an eccentrically positioned idler shaft. Background technique [0002] The idler structure is a common transmission structure in gear meshing. There are two main structural forms. The first structure is that the idler shaft rotates with the idler, and both ends of the idler shaft are supported in the bearing seat through bearings; One structure is that the idler shaft does not rotate with the idler, and the idler is supported on the idler shaft through internal bearings. Compared with the two idler structures, the second idler structure is more compact and flexible and can be supported at one end. [0003] The second type of idler structure is to increase the interference between the idler shaft and the support to prevent the idler shaft from rotating with the idler. The selection of the interference is particularly important. If it is too small, the idler shaft is prone to micro-rotation under the p...
