Abstract
The invention provides an unequal-pitch chain sprocket which comprises a sprocket and a chain which is meshed with the sprocket; the chain consists of an inner chain plate, an outer chain plate and a pin; the inner chain plate and the outer chain plate are connected by the pin to form the chain; the two neighboring pitches are unequal; the tooth profile curve of the sprocket tooth profile is composed of a dedendum circular arc and an addendum circular arc by connection; two tooth profiles are connected with the dedendum circular arc by a straight line. The chain sprocket has non-standard structure and belongs to the unequal-pitch chain sprocket. The chain sprocket has the advantages of simple structure, large carrying capacity, good firmness and durability and low cost, etc., can lead the equipment structure to be compact, and is particularly fit for the cold-drawing equipment of non-ferrous metal sections.
Description
(1) technical field
What the present invention relates to is a kind of driving mechanism, specifically a kind of chain sprocket driving mechanism.
(2) background technique
Chain-driven is a kind of common mechanical transmission mechanism.In Transmitted chains, being most widely used of bush roller chain, the geometrical shape of sprocket tooth form has NBS.But at some special occasions, for example on the non-ferrous metal section bar cold-draw equipment, the outer plate inner width spatial position that needs to use chain is as the sprocket teeth embedded location, and the while is carried out the section bar drawing with the hook loose joint on the drawbench traction gear.Also require the compact structure of chain sprocket driving mechanism, bearing capacity big simultaneously.The chain sprocket mechanism of standard can not satisfy these requirements.
(3) summary of the invention
The object of the present invention is to provide that a kind of compact structure, bearing capacity are big, the chain sprocket wheel with variable pitch of firm and durable.
The object of the present invention is achieved like this: it comprises sprocket wheel and the chain that is meshed with sprocket wheel; Chain is made up of inner plate, outer plate and bearing pin, and inner plate, outer plate connect chaining by bearing pin, and two adjacent pitches are unequal; The tooth curve of sprocket tooth form is connected to form by tooth root circular arc and tooth top circular arc, is connected with the tooth root circular arc by straight line between two profiles of tooth.
The present invention can also comprise:
1, the end of the inner plate of described chain is a circular arc, and its radius equates with the radius of the tooth root circular arc of sprocket wheel;
2, the pitch diameter D of sprocket wheel
0With the meropodium of tooth number Z, chain apart from t, short pitch t
1Between satisfy:
3, sprocket wheel outside diameter circle Dc and pitch diameter D
0, chain the radius r of inner plate end circular arc between satisfy: Dc=D
0+ 1.1r;
4, tooth top circular arc radius R and meropodium are apart from satisfying between the radius r of t, inner plate end circular arc: R=t+r;
5, base circle diameter (BCD) Dr and pitch diameter D
0, meropodium is apart from satisfying between the t: Dr=D
0-0.3t;
6, penalty coefficient e and short pitch t
1Between satisfy: e=0.08t

Chain sprocket of the present invention is a non-standard structure, belongs to chain sprocket wheel with variable pitch, it with standard etc. the pitch chain sprocket compare its main feature and be embodied in:
1, be particularly suitable for non-ferrous metal section bar cold-draw equipment, its outer plate inner width spatial position just in time is the sprocket teeth embedded location, simultaneously also be can with the hook loose joint on the drawbench traction gear, carry out the section bar cold-drawn.
2, the simple structure of chain, bearing capacity is big, firm and durable, cost are low.
3, when teeth number of sprocket identical, chain outer plate pitch t determines that under the situation, sprocket diameter is with t/t
1Ratio increase and reduce.T/t
11 o'clock, the diameter that sprocket diameter such as compares at the pitch chain sprocket is little, and diameter group is littler mutually with standard roller chain or leaf chain.This is for satisfying under former S=t-2 of sprocket tooth (r+e) and the structural requirement prerequisite, and chain sprocket of the present invention can reduce the diameter of sprocket wheel, makes compact equipment, and it is more reasonable to design.
4, when the cold-drawn section bar, under the constant situation of resistance of deformation (pulling force of need of work), tractive force and motor shaft torque or the reduction starting torque of sprocket diameter I to improve chain.
Simple structure that chain sprocket wheel with variable pitch of the present invention has, the compact structure that can make equipment, bearing capacity are big, firm and durable, low cost and other advantages, are particularly suitable for non-ferrous metal section bar cold-draw equipment.Also the design for non-standard chain pitch wheel driving mechanism provides a kind of new design considerations.
(4) description of drawings
Fig. 1 is the structural representation of sprocket wheel of the present invention;
Fig. 2 is the structural representation of chain of the present invention;
Fig. 3 is the plan view of Fig. 2.
(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the composition of chain sprocket wheel with variable pitch comprises sprocket wheel and the chain that is meshed with sprocket wheel; Simultaneously in conjunction with Fig. 2 and Fig. 3, chain is made up of inner plate 1, outer plate 3 and bearing pin 2, and inner plate, outer plate connect chaining by bearing pin, and two adjacent pitches are unequal, meropodium apart from t greater than short pitch t
1The tooth curve of sprocket tooth form is connected to form by tooth root circular arc ab and tooth top circular arc bc, is connected with the tooth root circular arc by straight line aa between two profiles of tooth.Should satisfy following requirement between this part during design:
1, the end of the inner plate of described chain is a circular arc, and the radius r of the tooth root circular arc of its radius r and sprocket wheel
