Description
Technical field
The utility model relates to driving chain field more particularly to a kind of wear-resisting low noise silent chains.
Background technique
The type of current 2 formula silent chain of round pin is very various, engaging contact position and divide from sprocket and sprocket,
It can be classified as engagement toothed chain, outer meshing silent chain, compound engaging tooth shape chain three categories are applied in this three categories silent chain
Most wide is compound engaging tooth shape chain.The fit form of combined type silent chain is 1 round pin of carrier bar, 2 formula (as shown in Fig. 1),
Open up circular through-hole 3 on carrier bar 1, round pin 2 be rotatably dispose in through-hole 3 (and in order to both guarantee smoothly to cooperate,
The diameter of through-hole 3 is greater than the diameter of round pin 2), this structure leads to compound engaging tooth shape chain when in use, and the meeting of round pin 2 exists
It spins in through-hole 3, and round pin 2 can constantly rub during this and the surrounding of squeezing through-hole 3 is along hole wall, lead to external toothing tooth form
Chain can generate biggish drive noise in transmission, and there is biggish wear problems between round pin 2 and carrier bar 1 simultaneously.
Utility model content
The utility model is in view of the above-mentioned problems, propose a kind of wear-resisting low noise silent chain.
The technical solution that the utility model is taken is as follows:
A kind of wear-resisting low noise silent chain, including carrier bar and round pin offer pin hole on the carrier bar, and the round pin is located at pin
In hole, the pin hole includes that two straight lines and two arc-shaped edges, the end of straight line are connected to the end of arc-shaped edges respectively
Together, it is parallel to each other between two straight lines, and the distance between two straight lines are equal to the diameter of round pin, the diameter of arc-shaped edges
Equal to the diameter of round pin, the arc-shaped edges are used for clip round pin.
The present apparatus is in transmission process, not with the sprocket wheel tooth engagement period, the contact side of round pin and pin hole when carrier bar Tensile
Formula becomes face contact from original line contact, improves bearing area；During sprocket engagement, round pin moved in pin hole by
" spinning " becomes to move linearly, and the transmission stability made in this way greatly improves, and while improving transmission stability, reduces transmission and makes an uproar
Sound；Rotation process contact position of the engaging-in process round pin in carrier bar is also to become face contact from line contact, is significantly improved wear-resisting
Performance.
The drive noise in transmission process can be greatly reduced in the present apparatus, while significantly reducing the mill of carrier bar and round pin
Damage, so that the service life is longer for carrier bar and round pin.
Optionally, there are two the pin holes.
Optionally, the edge of the carrier bar is provided with circular arc chamfering.
It optionally, further include teeth, the tooth pressure is set on carrier bar.
Optionally, there are two the teeth.
Optionally, the teeth are the triangle teeth with fillet point.
Optionally, the round pin is metal round pin, and the carrier bar is metal carrier bar.
The fit structure mode of pin hole and round pin is equally applicable to internal messing round pin formula silent chain and interior-and nibbles outside in this programme
Compound engagement round pin formula silent chain improves wear-resisting property and reduces drive noise.
The beneficial effects of the utility model are: the drive noise in transmission process can be greatly reduced, while substantially dropping
The low abrasion of carrier bar and round pin, so that the service life is longer for carrier bar and round pin.
Detailed description of the invention:
Fig. 1 is compound engaging tooth shape chain structure simplified schematic diagram；
Fig. 2 is wear-resisting low noise silent chain structure schematic diagram.
Each appended drawing reference in figure are as follows: 1, carrier bar, 101, circular arc chamfering, 102, teeth, 2, round pin, 3, through-hole, 4, pin hole,
401, straight line, 402, arc-shaped edges.
Specific embodiment:
Below with reference to each attached drawing, the utility model is described in detail.
As shown in Fig. 2, a kind of wear-resisting low noise silent chain, including carrier bar 1 and round pin 2 offer pin hole 4 on carrier bar 1, circle
Pin 2 is located in pin hole 4, pin hole 4 include two straight lines 401 and two arc-shaped edges 402, the end of straight line 401 respectively with circle
The end of arc side 402 links together, and is parallel to each other between two straight lines 401, and the distance between two straight lines 401 etc.
In the diameter of round pin 2, the diameter of arc-shaped edges 402 is equal to the diameter of round pin 2, and arc-shaped edges 402 are used for clip round pin 2.
The present apparatus is in transmission process, not with the sprocket wheel tooth engagement period, the contact of round pin 2 and pin hole 4 when 1 Tensile of carrier bar
Mode becomes face contact from original line contact, improves bearing area；During sprocket engagement, round pin 2 moves in pin hole 4
Become to move linearly by " spinning ", the transmission stability made in this way greatly improves, and while improving transmission stability, reduces transmission
Noise；Rotation process contact position of the engaging-in process round pin 2 in carrier bar 1 is also to become face contact from line contact, is significantly improved
Wear-resisting property.
The drive noise in transmission process can be greatly reduced in the present apparatus, while significantly reducing carrier bar 1 and round pin 2
Abrasion, so that carrier bar 1 is with round pin 2, the service life is longer.
As shown in Fig. 2, there are two pin holes 4.
As shown in Fig. 2, the edge of carrier bar 1 is provided with circular arc chamfering 101.
It as shown in Fig. 2, further include teeth 102, tooth pressure is set on carrier bar 1.
As shown in Fig. 2, there are two teeth 102.
As shown in Fig. 2, teeth 102 are the triangle teeth 102 with fillet point.
As shown in Fig. 2, round pin 2 is metal round pin 2, and carrier bar 1 is metal carrier bar 1.
The fit structure mode of pin hole 4 and round pin 2 is equally applicable to 2 formula silent chain of internal messing round pin and interior-in this programme
Compound 2 formula silent chain of engagement round pin is nibbled outside to improve wear-resisting property and reduce drive noise.
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
His relevant technical field similarly includes within the protection scope of the present utility model.
