Brief description
Fig. 1 is in the utility model embodiment, the sectional view of transmission device;
Fig. 2 is in the utility model embodiment, the three-dimensional structure diagram of chain and guide rail.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention to be described in further detail the application.
In the embodiment of the present application, a kind of chain transmission device is provided, by arranging on chain body and can relatively lead
The roller that rail rolls so that become rolling friction from traditional sliding friction between chain and guide rail, reduces equipment attrition.
Chain transmission device given by the present embodiment, as shown in Figures 1 and 2, including two guide rails be arrangeding in parallel 1,
Being arranged on the chain on guide rail 1, chain includes chain body 2, and the adjacent link place of company is provided with bearing pin 21.Chain body 2 includes putting down
Two row's interior lining panels 22 that row is arranged, are positioned between two row's interior lining panels 22 and the guide 23, Yi Jilian that be connected fixing with interior lining panel 22
Connect the outer liner plate 24 of adjacent two interior lining panels 22 of same row.Guide 23 outer surface is nested with the first roller 31, and the first roller 31 can
Rotate around guide 23 surface.It is equipped with identical chain on two guide rails 1, and be symmetrically set.It is provided with receiving inside guide rail 1
Portion 10, chain body 2 is housed in the cavity of receiving portion 10.Chain body 2 can roll in receiving portion 10.
Further, receiving portion 10 is simultaneously provided with position limiting structure inside guide rail 1.Specifically, position limiting structure include by
The upper limit part 11 downwardly extending directly over first roller 31, and by lower limit part upwardly extending immediately below the first roller
12.Upper limit part 11 and lower limit part 12 are positioned between two row's interior lining panels 22 of chain body 2, upper limit part 11 and lower limit
Part 12 defines that body 2, along the axial displacement of bearing pin 21, meanwhile, also defines the displacement in the vertical direction of chain body 2
(being perpendicular to the direction of guide rail surface).The interior lining panel 22 of chain body 12 side is positioned at the cavity of receiving portion 10, opposite side
Interior lining panel 22 is positioned at the containment portion of receiving portion 10.If with upper limit part 11 and lower limit while interior lining panel 22 first roller 31
Part 12 contacts, and can cause at least one contact surface generation sliding friction, and for avoiding this situation, the first roller 31 is at upper limit part
The connected mode of matched in clearance is used between 11 and lower limit part 12.So make, when the first roller 31 and upper limit part 11 connect
Touch when, its lower surface departs from lower limit part 12, and now the first roller 31 at upper limit part 12 surface scrolls;When the first rolling
When wheel 31 contacts with lower limit part 12, its upper surface departs from upper limit part 11, and now, the first roller 31 is on lower limit part 12 surface
Roll.
Further, bearing pin 21 is provided with extension towards guide rail 1 inner opposite end, and extension is provided with anti-creep liner plate 25, prolongs
Extending portion highlights anti-creep liner plate 25 surface portion and forms supporting part 211.The material 4 that conveyer is carried just is placed on guide rail both sides
Symmetrically arranged supporting part 211 surface, and due to the barrier effect of anti-creep liner plate 25, material 4 will not move between two guide rails 1
Move or outside removal guide rail.Being additionally provided with the second roller 32 between anti-creep liner plate 25 and outer liner plate 24, the second roller 32 is nested in pin
On the extension of axle 21, and can rotate about with bearing pin 21 for axle.Corresponding, guide rail 1 surface is provided with and the second roller 32 phase
The lug boss 13 abutting, lug boss 13 is distributed along guide rail bearing of trend so that the second roller 32 can roll on lug boss 13 surface
Dynamic.
It is also preferred that the left form a groove between lug boss 13 and lower limit part 12, in chain body 2 is inside guide rail 1
Liner plate 22 and outer liner plate 24 are contained in this groove.
Use such design, so that there are two stress between chain body 1 and the second roller 32 and guide rail 1
Point, reduces the pressure suffered by contact surface, reduces the damage of equipment.Additionally, when the material 4 of supporting part 241 carrying is overweight, bearing pin
21 just constitute lever, cause chain body 2 to be upturned for fulcrum with lug boss 13 with bearing pin 21 contact point, and upper limit part
The existence of 11, defines chain body 2 upwards relatively big large-scale displacement so that bearing pin 21 produces a pole in this case
Its small angle is deflected up, and the first roller 31 offsets with upper limit part 11 surface, and along upper limit part 11 surface scrolls,
Make bearing pin 21 substantially still keep the state paralleled with guide rail 1 surface, do not interfere with the transport of material 4.
Further, the guide rail 1 in the present embodiment is the standby aluminium rail of aluminum, and what guide rail 1 was paired is erected at pcb board Reflow Soldering
Or in the chamber of the equipment heating (or cooling) of wave-soldering, be used for transmitting pcb board.And the chain transmission device in the present embodiment,
It, depending on the concrete pcb board weight transported, can switch between sliding friction and rolling friction two states.Concrete,
Set maximum static friction force between the first roller 31 and upper limit part 11 or lower limit part 12 as F1, the second roller 32 and projection
Maximum static friction force between portion 13 is F2, the maximum static friction force between the first roller 31 and guide 23 is F3, the second roller 32
And the maximum static friction force between bearing pin 21 is F4;When the pcb board weight transmitting makes F1> F3When, the first roller 31 starts rolling
Dynamic, on the contrary F3> F1When, the first roller 31 does not rolls, but slides on guide rail 1.Same, work as F2During > F4, second
Roller 32 at lug boss 13 surface scrolls, otherwise, F4 > F2When, the second roller 32 slides on lug boss 13 surface.Thus real
Show the chain purpose that sliding friction and rolling friction two states mutually switch on guide rail 1.The two contact surface is in
The state of minimum friction, reduction equipment is due to the loss causing that rubs, the service life of extension device, and meanwhile, material transports
Process is more smooth and easy, lowers equipment failure rate, improves production efficiency.
Chain transmission device given by the utility model, by arranging first can rolling along track in chain junction
Roller so that chain can convert between track between sliding friction and rolling friction, significantly reduces the mill of equipment
Damage degree, increases transmission device service life;Bearing pin extension is provided with the second roller, adds putting forth effort between chain and guide rail
Point, reduces the pressure that the two contact surface bears, reduces equipment loss further;Guide rail is provided with the receiving portion accommodating chain, prevents
Due to end part of pin shaft load-bearing, cause chain body to be upturned, maintain the balance in chain.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to assert this Shen
Being embodied as please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of the present application is conceived, some simple deduction or replace can also be made.
