Background technology
In the transmission of precision equipment, can be typically driven using precision machined gear, and for the essence of long range
Close transmission, then can be typically driven using screw rod, but the processing of screw rod and associated gear is more complicated, while screw drive exists
In the case of high-bearing capacity, it is easy to which effect of attrition precision occurs, if using belt transmission, being easy to the change because environment
Change and cause that the tensile force of belt changes so that belt pulley occurs skidding to a certain extent, or because of belt tension
Local difference, has influence on the asynchronous of pulley rotation speed, so as to have influence on the precision of transmission；
Chain gear transmission is often used as in high-bearing capacity using the low tension liter property of chain and low advantage affected by environment
Transmission because the elasticity of Chain link for chain grate itself and press-fiting the problem of precision, in the case of some chain inclined works, chain link
Between irregular swing can occur, the precision of transmission is influenceed, while chain is fixed using chain bearing pin static pressure dress in itself, in length
After time use, chain nodal plate is easy to relative chain bearing pin and is shifted over so that the swingable amplitude increase between link, influences chain
The transmission accuracy of bar.
The content of the invention
The technical problem to be solved in the present invention is：The chain link between chain in the prior art is overcome easily to swing influence transmission
A kind of problem of precision, there is provided precision drive chain.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of precision drive chain, including inner link and outer link；
The outer link includes two exterior chain nodal plates, and a press mounting hole is each provided with the transverse ends of the exterior chain nodal plate
A；
The inner link includes two inner link pieces, and a press mounting hole is each provided with the transverse ends of the inner link piece
B；
The position of described two inner link pieces correspondence press mounting hole B is provided with a cushion block for annular；
Between the inner link piece and exterior chain nodal plate, the annular position of correspondence cushion block is provided with a cavity for arc,
The opening direction of the arc is provided with one towards inner link piece or the longitudinal middle part of exterior chain nodal plate in the cavity of the arc
The elastic component of individual arc realizes the support to inner link piece and exterior chain nodal plate.
As further innovation of the invention, a wavy spring shim is included in the elastic component.
As further innovation of the invention, the height of the height less than cavity both sides of the cavity medium position.
As further innovation of the invention, the position of exterior chain nodal plate correspondence cavity is provided with the reinforcement of arc
Piece.
Used as further innovation of the invention, the cavity includes the arc groove being arranged on exterior chain nodal plate, described outer
Arc groove and reinforcing chip on chain nodal plate are formed by outer link piece inner side punch process.
The beneficial effects of the invention are as follows：
1st, the present invention sets spring leaf so as to improve the support force at chain link two ends by one at link plate edge, reduces chain
The deflection degree of section, so as to improve the transmission accuracy of chain.
2nd, compared to block rubber, it is smaller with the contact area of chain link plate piece, force of sliding friction for corrugated spring leaf
It is lower, while the metal material of spring leaf has good oleophylic performance, compared to other organic elastomer materials, it is not easy to occur
Aging, while a certain degree of lubrication can be carried out, the elastic release dynamics of wave structure and direction are also more uniform.
3rd, height of the height in the middle part of cavity less than cavity both sides so that the support force in the middle part of spring leaf is greater than both sides
Support force, so as to adapt to the elastic deformation power of the elastic deformation power more than both sides of chain link piece end.
4th, reinforcing chip can be prevented because the situation of the intensity decreases that the part of chain nodal plate is emptied and occurred.
5th, compared to turnery processing, more preferably, intensity is also higher for its metal compaction degree for punch process.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant with the present invention.
As shown in Fig. 1 ~ 5, the present invention is a kind of precision drive chain, including inner link and outer link；
The outer link includes two exterior chain nodal plates 2, is each provided with one in the transverse ends of the exterior chain nodal plate 2 and press-fits
Hole A；
The inner link includes two inner link pieces 3, is each provided with one in the transverse ends of the inner link piece 3 and press-fits
Hole B；
The position of the corresponding press mounting hole B of described two inner link pieces 3 is provided with a cushion block for annular 4；
Between the inner link piece 3 and exterior chain nodal plate 2, the annular position of correspondence cushion block 4 is provided with a sky for arc
Chamber 5, the reinforcing chip 6 of arc, the height of the medium position of the cavity 5 are provided with the position of the exterior chain nodal plate 2 correspondence cavity 5
Less than the height of the both sides of cavity 5, the opening direction of the arc towards inner link piece 3 or the longitudinal middle part of exterior chain nodal plate 2, in institute
Support of the wavy spring shim realization to inner link piece 3 and exterior chain nodal plate 2 is provided with the cavity 5 for stating arc；
Arc groove groove and reinforcing chip 6 on the exterior chain nodal plate 2 are formed by the inner side punch process of outer link piece 2.
The horizontal power received in chain and when being distorted, between exterior chain nodal plate 2 and inner link piece 3 because Chain link for chain grate from
Body elasticity and chain pin 1 certain frame amount and there is opposing oscillatory, influence chain transmission accuracy, by spring shim to outer link
Piece 2 and inner link piece 3 provide support force, to reduce the amplitude of fluctuation between exterior chain nodal plate 2 and inner link piece 3 as far as possible, from
And improve precision.
The technological progress of this product has：
1st, spring leaf is set so as to improve the support force at chain link two ends at link plate edge by one, reduces the inclined of chain link
Throw, so as to improve the transmission accuracy of chain.
