Abstract
The utility model discloses a kind of new work engine precision-sleeve chain inner sheet, including engine precision-sleeve chain inner sheet body, transition arcs of the engine precision-sleeve chain inner sheet body between one group of symmetrical circle and one group of circle are constituted, pin-and-hole is provided with described one group symmetrical circle, the engine precision-sleeve chain inner sheet body upper surface edge is provided with chamfering.The beneficial effects of the utility model are the pardons for adding chain, make chain drive more smooth, add the service life of chain, reduce noise sound, practical.
Description
Technical field
The utility model is related to bush(ing) chain, particularly a kind of new work engine precision-sleeve chain inner sheet.
Background technology
Bush(ing) chain, which refers to, does not have roller in component part, chain of the sleeve surface in engagement directly with sprocket wheel tooth contact.Mesh
Piece collection cold punching die production shaping, is engaged, the slice, thin piece section produced with gear in preceding market engine precision-sleeve chain
Concordantly（As illustrated in figs. 2-3）.When being engaged after assembling chain with engine internal gear, pardon is poor, in the running, interior chain
Friction is produced with engine internal gear root on the inside of piece and cause abnormal sound noise, while reducing the service life of chain.
Utility model content
The purpose of this utility model is to solve the above problems, devise in a kind of new work engine precision-sleeve chain
Piece.
Realize that above-mentioned purpose the technical solution of the utility model is, a kind of new work engine precision-sleeve chain inner sheet, including
Engine precision-sleeve chain inner sheet body, the engine precision-sleeve chain inner sheet body is by one group of symmetrical circle and one group of circle
Between transition arcs composition, be provided with pin-and-hole, the engine precision-sleeve chain inner sheet body on described one group symmetrical circle
Chamfering is provided with marginal surface.
The chamfering is 45 degree.
The circle and pin-and-hole concentric.
The engine precision-sleeve chain inner sheet body is the monolithic being made up of carbon steel alloy.
The engine precision-sleeve chain inner sheet body is symmetrical structure.
The new work engine precision-sleeve chain inner sheet made using the technical solution of the utility model, in slice, thin piece one side outer rim
Fall 45 degree of angles inclined-plane at place, solves the problem of being previously mentioned in above-mentioned background technology, adds the pardon of chain, make chain drive
It is more smooth, the service life of chain is added, noise sound is reduced, it is quieter when using with stronger practicality.

Embodiment
In description of the present utility model, it is necessary to explanation, term " on " indicate orientation or position relationship be based on
Orientation shown in the drawings or position relationship, or the orientation usually put when using of the utility model product or position relationship,
It is for only for ease of description the utility model and simplifies description, rather than indicates or imply that the device or element of meaning must have
Specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
The utility model is specifically described below in conjunction with the accompanying drawings, as Figure 1-4, a kind of new work engine precision set
Cylinder chain inner sheet, including engine precision-sleeve chain inner sheet body（1）, the engine precision-sleeve chain inner sheet body（1）Be by
Pin-and-hole is provided with transition arcs composition between one group of symmetrical circle and one group of circle, described one group symmetrical circle（2）, it is described to start
Machine precision-sleeve chain inner sheet body（1）Chamfering is provided with top surface edge（3）；The chamfering（3）For 45 degree；The circle and pin-and-hole
（2）Concentric；The engine precision-sleeve chain inner sheet body（1）It is the monolithic being made up of carbon steel alloy；The engine
Precision-sleeve chain inner sheet body（1）For symmetrical structure.
The characteristics of the present embodiment is, engine precision-sleeve chain inner sheet body be by one group of symmetrical circle and one group of circle it
Between transition arcs composition, be provided with pin-and-hole, engine precision-sleeve chain inner sheet body upper surface edge on one group of symmetrical circle
Chamfering is provided with, chamfering is 45 degree, adds the pardon of chain, makes chain drive more smooth, adds the use longevity of chain
Life, reduces noise sound.
In the present embodiment, 45 is fallen at slice, thin piece one side outer rim using particular manufacturing craft to engine precision-sleeve chain inner sheet
Angle inclined-plane is spent, assembling chain is carried out by one group of pin-and-hole, after being completed, chain is added when being engaged with engine internal gear
Pardon, make chain drive more smooth, increase chain service life, meanwhile, engine precision-sleeve chain inner sheet body be by
The symmetrical structure of transition arcs composition between one group of symmetrical circle and one group of circle, and be made up of conventional carbon steel alloy, cost
Low, practical, quieter when using, using effect is more preferable.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Some variations that personnel may make to some of which part embody principle of the present utility model, belong to the utility model
Protection domain within.
