Description
Technical field
The present invention relates to a kind of precision drive chain, belong to the driving mechanism field of precision equipment.
Background technique
In the transmission of precision equipment, precision machined gear generally can be used to carry out transmission, and for the precision drive of long distance, screw rod then generally can be used to carry out transmission, but the processing more complicated of screw rod and associated gear, screw drive is when high-bearing capacity simultaneously, be easy to effect of attrition precision occurs, if use belt transmission, then be easy to because the change of environment makes the tension force of belt change, make belt pulley generation skidding to a certain extent, or because the local difference of belt tension, have influence on the asynchronous of pulley rotation speed, thus have influence on the precision of transmission,
Sprocket driving utilizes the low tension liter property of chain and low advantage affected by environment, often be used as the transmission of high-bearing capacity, because the elasticity of Chain link for chain grate self and the problem press-fiting precision, when some chain inclined work, irregular swing can be there is between chain link, affect the precision of transmission, chain itself adopts chain bearing pin static pressure dress fixing simultaneously, after a long time use, chain nodal plate is easy to relative chain bearing pin and is shifted, swingable amplitude between linking is increased, affects the transmission accuracy of chain.
201320292650.9 provide a kind of high-accuracy link chain mechanism, and it is mainly through multiple axle sleeve type bearing and adopt nut to fix, and realize the accurate manufacture of chain and accurate location, but said structure still also exist more shortcoming:
1, the more complex structure of number of spare parts, weight is large.
2, chain self inertia is comparatively large, is easy in the anxious stopping time, promotes sprocket wheel and certain rotation occurs, thus affect normal equipment operation precision.
3, need when chain manufactures artificial to carry out fastening to screw-nut, when quantity is more, be difficult to the validity ensureing that screw, nut are fixing, because during screw volume production, major part adopts thread rolling machine to carry out the processing of screw thread, and precision is low, and stress is large.
Summary of the invention
The technical problem to be solved in the present invention is: the chain link overcome in prior art between chain easily swings the problem affecting transmission accuracy, provides a kind of precision drive chain.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of precision drive chain, comprises inner link and outer link;
Described outer link comprises two outer link sheets, is respectively provided with a press mounting hole A in the transverse ends of described outer link sheet;
Described inner link comprises two inner link sheets, is respectively provided with a press mounting hole B in the transverse ends of described inner link sheet;
An annular cushion block is provided with in the position of the corresponding press mounting hole B of described two interior chain inner link sheets;
Between described inner link sheet and outer link sheet, the annular of corresponding cushion block is provided with the cavity of an arc, the opening direction of described arc is towards the longitudinal middle part of inner link sheet or outer link sheet, and the elastic component being provided with an arc in the cavity of described arc realizes the support to inner link sheet and outer link sheet.
As further innovation of the present invention, comprise a wavy compression spring at described elastic component.
As further innovation of the present invention, the height of described cavity medium position is less than the height of cavity both sides.
As further innovation of the present invention, be provided with the reinforcing chip of arc in the position of the corresponding cavity of described outer link sheet.
As further innovation of the present invention, described cavity comprises the arc groove be arranged on outer link sheet, and the arc groove on described outer link sheet and reinforcing chip are by forming punch process inside outer link sheet.
The invention has the beneficial effects as follows:
1, the present invention arranges spring sheet thus the support force at raising chain link two ends by one at link plate edge, reduces the deflection degree of chain link, thus improves the transmission accuracy of chain.
2, corrugated spring sheet is compared to block rubber, the area of contact of itself and chain nodal plate is less, force of sliding friction is lower, the metal material of spring sheet has good oleophylic performance simultaneously, compared to other organic elastomer materials, be less likely to occur aging, lubrication to a certain degree can be carried out simultaneously, the elasticity release dynamics of wave structure and direction also more even.
3, the height in the middle part of cavity is less than the height of cavity both sides, makes the support force in the middle part of spring sheet be greater than the support force on both sides, thus the elastic strain power adapting to chain nodal plate end is greater than the elastic strain power of both sides.
4, reinforcing chip can prevent the situation that the intensity occurred because the local of chain nodal plate empties reduces.
5, punch process is compared to turnery processing, and its metal compaction degree is better, and intensity is also higher.

Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Fig. 1 ~ 5, the present invention is a kind of precision drive chain, comprises inner link and outer link;
Described outer link comprises two outer link sheets 2, is respectively provided with a press mounting hole A in the transverse ends of described outer link sheet 2;
Described inner link comprises two inner link sheets 3, is respectively provided with a press mounting hole B in the transverse ends of described inner link sheet 3;
An annular cushion block 4 is provided with in the position of described two corresponding press mounting hole B of interior chain inner link sheet 3;
Between described inner link sheet 3 and outer link sheet 2, the annular of corresponding cushion block 4 is provided with the cavity 5 of an arc, the reinforcing chip 6 of arc is provided with in the position of the corresponding cavity 5 of described outer link sheet 2, the height of described cavity 5 medium position is less than the height of cavity 5 both sides, the opening direction of described arc, towards the longitudinal middle part of inner link sheet 3 or outer link sheet 2, is provided with the support that a wavy compression spring realizes inner link sheet 3 and outer link sheet 2 in the cavity 5 of described arc;
Arc groove groove on described outer link sheet 2 and reinforcing chip 6 are by forming punch process inside outer link sheet 2.
The transverse direction that chain is subject to power and when being distorted:
Opposing oscillatory is there is because of the natural resiliency of Chain link for chain grate and certain frame amount of chain pin 1 between outer link sheet 2 and inner link sheet 3, affect the transmission accuracy of chain, by the Diastolic Force of compression spring self, power is provided support to outer link sheet 2 and inner link sheet 3, to reduce the amplitude of fluctuation between outer link sheet 2 and inner link sheet 3 as much as possible, also can make chain return timely after swinging simultaneously, thus raising precision;
