It puts, is changed to chain roller by the improvement of structure, and by sprocket wheel, it is ensured that chain operation is steady, smooth, with small vibration, and the adjusting of chain roller
It is more convenient, it can preferably meet the straightness between two chain rollers, so as to ensure that chain operation is more stable, eliminates safe hidden trouble.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of chain wheel device for counterweight chain, including rack and chain roll shaft, the both ends of the chain roll shaft are passed through respectively
The both sides of the rack are through at, rolling bearing is cased in the middle part of the chain roll shaft, the outside of the roller bearing is cased with chain roller, institute
The both sides for stating chain roller are respectively arranged with the first limit casing and the second limit casing, and first limit casing and the second limiting
Casing is mutually butted on the both sides of the rolling bearing inner ring respectively, is set on the excircle of the chain roller fluted；The chain roll shaft
One end be internally provided with the first grease channel, the downside in the middle part of the chain roll shaft is provided with oil groove, second stop collar
Be provided with the second grease channel on the inside of pipe, first grease channel, oil groove and second grease channel according to
Secondary connection for the lubrication of the rolling bearing, avoids the phenomenon that clamping stagnation occur between the chain roller and the chain roll shaft, it is ensured that
Chain operation is steady, smooth.
Preferably, first limit casing and the second limit casing are fixed on the chain roll shaft by lock-screw
Outside, first limit casing and the second stop collar are used for the limiting of the chain roller axial direction so that the chain roller installation
Simply, it is easy to adjust, it is ensured that the straightness between two chain rollers improves safety in utilization.
Further, oil nozzle is provided on the outside of first grease channel, for the filling of lubricating oil.
Further, the chain roller is fixed on the outside of the rolling bearing by clamp spring, and installation is simple.
The beneficial effects of the utility model are：(1) by setting chain roller, reduce resistance during chain operation, improve
Mechanically operated efficiency；(2) first grease channel, oil groove and second grease channel is set to avoid the chain
There is the phenomenon that clamping stagnation between roller and the chain roll shaft, it is ensured that chain operation is steady, smooth；(3) by setting first limit
Position casing and the second limit casing, convenient for the chain roller axial direction, it is ensured that the straightness between two chain rollers improves
Safety in utilization.
