Description
Technical field
The synchronizing wheel component technology field in SMT chip mounters is the utility model is related to, more particularly to a kind of screw bolt-type is synchronous
Wheel.
Background technology
Synchronous wheel assembly with transmission efficiency, it is steady the features such as and be widely applied in the transmission mechanism of various equipment.It is existing
The transmission mechanism for having SMT chip mounters also has many synchronous wheel assemblies, as shown in figure 1, the synchronous wheel assembly include synchronizing wheel 1,
Fixing axle 2, bearing 3 and fastening screw 5, described one end of fixing axle 2 are connected by bearing 3 with synchronizing wheel 1, fastening screw 5 one
End bear against bearing after being threadedly coupled with synchronizing wheel, prevent bearing 3 from leaving the bearing hole of synchronizing wheel 1.This synchronous wheel assembly
Major defect has：If the 1st, the one end of fastening screw 5 be pressed in the outer round surface of bearing 3 power it is excessive be easy for allowing bearing 3 to be deformed, meeting
Synchronous wheel assembly is caused normally to be driven because bearing 3 is stuck；If the one end of fastening screw 5 is pressed in the outer round surface of bearing 3
Power is too small to be easy for allowing bearing 3 to spin off from the bearing hole of synchronizing wheel 1；As can be seen here, how to hold to twisting fastening screw 5
Elasticity is to need certain experiences.But when the assembling of synchronous wheel assembly reaches requirement, after certain time, the meeting of bearing 3
There is certain abrasion, influence the service life of synchronous wheel assembly.
Therefore, existing synchronous wheel assembly need to improve to the position limiting structure of fixing axle 2 or bearing 3, therefore provide a kind of bolt
Type synchronizing wheel.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided one kind can prevent fixing axle,
Bearing departs from the screw bolt-type synchronizing wheel of synchronizing wheel.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of screw bolt-type synchronizing wheel described in the utility model, including synchronizing wheel, fixing axle, bearing and fastening screw, institute
Synchronizing wheel end face is stated by bearing with fixing axle one end to be connected；The synchronizing wheel other end is connected with Limit Bearing, institute
State after fastening screw one end sequentially passes through Limit Bearing, synchronizing wheel and be mutually threadedly coupled with fixing axle one end.
Further, the synchronizing wheel is provided with bearing hole, interstitial hole and limit shaft bearing bore, bearing and is embedded in bearing hole
In, Limit Bearing is embedded in limit shaft bearing bore.
Further, coordinate between the fastening screw and interstitial hole in gap.
After said structure, the utility model has the beneficial effect that：A kind of screw bolt-type synchronizing wheel described in the utility model,
Including synchronizing wheel, fixing axle, bearing and fastening screw, the synchronizing wheel end face is connected by bearing with fixing axle one end；
The synchronizing wheel other end is connected with Limit Bearing, described fastening screw one end sequentially pass through after Limit Bearing, synchronizing wheel with
Fixing axle one end is mutually threadedly coupled.When using the utility model, after fastening screw one end sequentially passes through Limit Bearing, synchronizing wheel
Mutually be threadedly coupled with fixing axle one end, the screw termination of fastening screw tight against being pressed on the end face of Limit Bearing, synchronizing wheel around
When fixing axle rotates, Limit Bearing can prevent fastening screw from followed by synchronizing wheel rotation, and the structure had not both interfered with bearing, limit
It the gearing of position bearing, can also prevent bearing, fixing axle from departing from the bearing hole of synchronizing wheel, ensure the transmission effect of synchronizing wheel
Fruit, while can effectively extend the service life of synchronizing wheel.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 2 to Figure 3, a kind of screw bolt-type synchronizing wheel described in the utility model, including synchronizing wheel 1, fixing axle 2,
Bearing 3 and fastening screw 5, the end face of synchronizing wheel 1 are connected by bearing 3 with the one end of fixing axle 2；The synchronizing wheel 1 is set
Bearing hole 1-1, interstitial hole 1-2 and limit shaft bearing bore 1-3 are equipped with, bearing 3 is embedded in bearing hole 1-1.
The other end of synchronizing wheel 1 is connected with Limit Bearing 4, and Limit Bearing 4 is embedded in limit shaft bearing bore 1-3.Tightly
Gu tight against being pressed on the end face of Limit Bearing 4, described one end of fastening screw 5 sequentially passes through limit shaft for the screw termination of screw 5
Mutually it is threadedly coupled with the one end of fixing axle 2 after holding 4, synchronizing wheel 1.The structure had not both interfered with bearing, the transmission of Limit Bearing 4 is made
With, can also prevent bearing 3, fixing axle 2 depart from synchronizing wheel 1 bearing hole 1-1, ensure synchronizing wheel 1 transmission effect.
As a kind of preferred embodiment of the present utility model, coordinate between the fastening screw 5 and interstitial hole 1-2 in gap；
Fastening screw 5 and interstitial hole 1-2 is avoided to produce friction and influence the normal transmission of synchronizing wheel 1.
When using the utility model, fastening screw one end sequentially pass through after Limit Bearing, synchronizing wheel with fixing axle one end
Mutually be threadedly coupled, the screw termination of fastening screw tight against being pressed on the end face of Limit Bearing, synchronizing wheel around fixing axle rotate when,
Limit Bearing can prevent fastening screw from followed by synchronizing wheel rotation, and the structure had not both interfered with the transmission of bearing, Limit Bearing
Effect, it can also prevent bearing, fixing axle from departing from the bearing hole of synchronizing wheel, ensure the transmission effect of synchronizing wheel, while can have
Effect extends the service life of synchronizing wheel.
