Specific embodiment
The utility model is described further below with reference to embodiment, but is not limited to the content on specification.
As shown in Figure 1, Figure 2 and Figure 3, the utility model relates to the transmission device that a kind of device has Tooth wheel with changeable teeth, it includes
Transmission belt 1 and Tooth wheel with changeable teeth 2, transmission belt 1 are sleeved on Tooth wheel with changeable teeth 2, carry out transmission effect, and Tooth wheel with changeable teeth 2 includes tooth base 21
With oscillating tooth 22, oscillating tooth 22 includes plug-in unit 221, teeth 222 and teeth seat 223,223 one of plug-in unit 221, teeth 222 and teeth seat
Molding, the radial section of teeth seat 223 are that fan is cyclic annular, and fan ring is a part that an annulus is intercepted by sector, and annulus includes big
Circumference and small circumference, after intercepting fan ring, fan ring also includes big circumference and small circumference, and the great circle perimeter surface of teeth seat 223 is uniformly set
It is equipped with teeth, the small circumference surface middle part of teeth seat 223 is provided with plug-in unit, and provided circumferentially about fluted the 211 of tooth base 21, plug-in unit
221 are inserted into groove 211, and oscillating tooth 22 is installed in groove 211 by the two clearance fit, constitute Tooth wheel with changeable teeth 2, teeth seat
223 be bonded with tooth base 21 make oscillating tooth 22 closely fitting tooth base 21 so that is connected between oscillating tooth 22 is stronger.
The number of oscillating tooth 22 is more than or equal to two, is provided with connecting hole 2221, connector 2222 in the teeth 222 of oscillating tooth 22
Two neighboring oscillating tooth 22 is connected as one across connecting hole 2221, after each oscillating tooth 22 connects, is formed to 21 center of circle of tooth base
With joint efforts, it can be avoided oscillating tooth 22 to fall, connector 2222 is flexible connecting member, and generation size is not accurate when avoiding installing,
The problem of can not installing, connector 2222 preferably connects rope, and unidirectional anti-tripping, oscillating tooth tooth is equipped on connection rope
During rotation, the direction that oscillating tooth 22 runs to power suffered when each position is different, therefore connector 2222 is when long for wheel 2
Between elasticity can occur in use process slowly slow down, cause to connect unsteady situation between oscillating tooth 22, influence equipment and normally transport
Row, it is unidirectionally anti-tripping to prevent connection rope in use since elasticity reduction causes to loosen between oscillating tooth 22, when even
It is unidirectionally anti-tripping to make to connect rope to the extension of 221 direction of plug-in unit when splicing rope elongates, guarantee the connection between each oscillating tooth 22
Fastening, prevents oscillating tooth 22 from falling off, while ensure that device operates normally, it is preferable that is provided in the teeth 222 of 22 two sides of oscillating tooth
Two adjacent oscillating tooths 22 are connected as one by connecting hole 2221 by connector 2222.
Transmission belt 1 is sleeved on Tooth wheel with changeable teeth 2, and since Tooth wheel with changeable teeth 2 is ceaselessly rotating, each oscillating tooth 22 is connected as one
Body, it is acute angle with centripetal force that for centripetal force towards the center of circle of tooth base 21, the power and teeth 222 on transmission belt 1 are tangent, therefore, transmission
The connection tightness for more fastening oscillating tooth 22 Yu tooth base 21 with 1, avoids the case where oscillating tooth 22 falls off during rotation, shadow
Normal transmission is rung, the two sides of Tooth wheel with changeable teeth 2 are respectively arranged with baffle, and wherein side is dismountable block plate, when replacing oscillating tooth 22,
It does not need to dismantle the connector 2222 between oscillating tooth 22, directly dismountable baffle is taken away, Tooth wheel with changeable teeth 2 is laid flat i.e.
Can, due to being clearance fit between plug-in unit 221 and groove 211, oscillating tooth 22 can directly fall off from tooth base 21, then directly
Tooth base 21 is changed to new oscillating tooth 22, the oscillating tooth 22 to fall off on tooth base 21 can continue to apply on other tooth bases 21, reach
To the purpose of waste utilization, a large amount of resource is saved.
When in use, oscillating tooth 22 is inserted into the groove 211 of tooth base 21 for the present apparatus, after the completion of each oscillating tooth 22 inserts,
It installs the connecting hole 2221 in teeth 222 by connector 2222 to be connected as one each oscillating tooth 22, connector 2222 can be excellent
The flexible connecting members such as spring or connection rope are selected as, it is simple to operate, when connector 2222 is connection rope, connecting
Anti- take-off is installed on rope, prevents connection rope from there is a situation where loosening, causing oscillating tooth 22 to fall off during rotation, influencing
The normal transmission of Tooth wheel with changeable teeth 2 and transmission belt 1 does not need to carry out entire Tooth wheel with changeable teeth 2 more when needing to change transmission ratio
It changes, only needs to change oscillating tooth 22, be first placed on the ground baffle, transmission belt 1 is unloaded, then by 2 water of Tooth wheel with changeable teeth
Placing flat is on baffle, since oscillating tooth 22 and tooth base 21 are clearance fit, between oscillating tooth 22 is removed, it is very convenient, at
This is cheap, saves a large amount of time and labour, and after being installed, transmission belt 1 is sleeved on for oscillating tooth 22 needed for installing later
On Tooth wheel with changeable teeth 2, baffle is installed, it can normal use.
The preferably friction band of transmission belt 1, can also be suitable for transmission belts 1 of Tooth wheel with changeable teeth 2, friction band is with intensity for other
It is high, brake force is big, wear rate is low etc., and advantages, no asbestos tree refer to braided braking band in addition to the excellent of asbestos resin braided braking band
Point is outer, also has to human body non-hazardous, no pollution to the environment characteristic.
As shown in figure 4, transmission belt 1 can also be spliced transmission belt, it is spliced by multiple identical cell cubes 11, single
First body 11 is cube, and cell cube 11 is equipped with mounting hole 1 and mounting hole 2 112, when carrying out assembled, by a unit
Mounting hole 1 on body 11 is connect with the mounting hole 2 112 in another cell cube 11, guarantees engaging biography with Tooth wheel with changeable teeth 2
When dynamic, increasing friction force and manufacture noise will not be abutted between each cell cube 11 of transmission belt 1, at the same again can according to demand,
It is spliced into various sizes of transmission belt 1, the expense of replacement transmission belt 1 is saved, reduces costs, the surface bonding of cell cube 11
Flexible rubber makes in transmission process when mutually abutting or colliding between two adjacent cell cubes 11, being capable of reduction unit
The abrasion of body 11 increases the service life of transmission belt 1, while reducing noise, reduces noise pollution, increase transmission belt 1 with
The frictional force of 2 contact surface of Tooth wheel with changeable teeth enables what transmission belt 1 more fastened to be bonded with Tooth wheel with changeable teeth 2, avoids that transmission belt occurs
It the phenomenon that 1 skidding, is allowed to normally to be driven.
Obviously, the above embodiment of the utility model is merely examples for clearly illustrating the present invention,
And it is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, it is stated upper
It can also be made other variations or changes in different ways on the basis of bright.Here all embodiments can not be given thoroughly
It lifts.It is all to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
Protection scope column.
