Abstract
The invention relates to the technical field of connection and fastening of mechanical parts. The invention aims to provide a design technology for a non-standard flat washer. The invention adopts a new design method of a connecting hole, can realize smooth connection between the parts, can also realize connection of at least two kinds of different center distances in a certain range, and reduces the cost. The flat washer has a brief and compact structure and facilitates integrated and standardized design and manufacturing.
Description
Technical field
The present invention relates to a kind of connection and tightening technology field of component of machine.
Background technique
Plain washer 1 is the standard component of scyewed joint.The general connection that is used for metal parts increases bearing area, prevents the injuring part surface.Plain washer (as shown in Figure 1 and Figure 2), the ring of sky in being generally, thickness is much smaller than its diameter.Its connecting hole 2 is positioned at the center of plain washer, is manhole 3, and its effect is the turnover for screw or bolt, and the internal diameter of its manhole 3 is all greater than the external diameter of the corresponding position of screw or bolt.The benefit of doing like this is when a little dislocation is arranged between the unthreaded hole that is connected or the tapped hole centre distance, also can guarantee to connect smoothly.But when centre distance misplaces when serious, that perhaps has a mind to as required staggers during centre distance, and the plain washer 1 of standard just can't be satisfied the demand.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of plain washers that can realize that within the specific limits at least two kinds of different centre distance parts connect are provided.
Technological scheme of the present invention is: packing ring is provided with an above bar hole; Described bar hole comprises two sections straightways that are parallel to each other, connects two sections circular arcs of two straightways.
Radially be provided with a bar hole on the described packing ring; Intersect described bar hole and packing ring medial axis.
Radially be provided with two bar holes on the described packing ring; Described two bar holes are vertically intersected on the packing ring medial axis.
Described bar hole is two; Described packing ring is provided with two bar holes that are parallel to each other; The packing ring medial axis equates to the distance of two bar holes.
Described packing ring is square, triangle or ellipse.
The present invention adopts connecting hole, both can realize the smooth connection between the part; Simultaneously can realize the connection of at least two kinds of different centre distance within the specific limits; Reduce cost.The present invention's compactness simple for structure is convenient to integrated, standardized designs manufacturing.
