Abstract
The utility model provides an unequal pitch chain and chain sprocket, comprising the chain sprocket and the chain meshed with the chain sprocket; the chain consists of an inner chain plate, an outer chain plate and a pin roll; the inner chain plate and the outer chain plate are connected to form the chain through the pin roll; two adjacent pitches are not equal; a circular arc of a tooth root and a circular arc of a tooth crest are connected to form a tooth profile curve of the chain sprocket; the two tooth profiles are connected with each other through a straight line and the circular arc of the tooth root. The structure of the chain and the chain sprocket of the utility model is non-standard structure, pertaining to the unequal pitch chain and chain sprocket. The unequal pitch chain and chain sprocket has the advantages of simple structure, being capable of leading the structure of the device to be compact, great bearing capacity, firmness and durability and low cost, etc., and is particularly suitable for cold-draw equipment of a nonferrous metal profile.
Description
(1) technical field
The utility model relates to 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 purpose of this utility model 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 purpose of this utility model is achieved in that 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 utility model 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 utility model 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
1＞1 o'clock, the diameter that sprocket diameter such as compares at the pitch chain sprocket was 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 utility model 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 utility model 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 the utility model sprocket wheel;
Fig. 2 is the structural representation of the utility model chain;
Fig. 3 is the plan view of Fig. 2.
(5) embodiment
For example the utility model 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:
