Utility model content

The purpose of this utility model is that there is provided a kind of group of high-speed steel shaped steel polishing roll in view of the shortcomings of the prior art Part, the component use mixed binding roll, by the tooth of main shaft and countershaft, groove engage, make product wearability (uniformity), Impact flexibility, thermal fatigue resistance and tensile strength are obtained for raising, and improve the service life of product and the table of product Face quality.

Realizing the technical scheme of the utility model purpose is：A kind of component of high-speed steel shaped steel polishing roll, its feature exists In：Including two high-speed steel shaped steel polishing rolls, wherein one as main shaft, another is used as countershaft, both intermeshings；It is main Axle includes roll neck, the bearing rib roll neck positioned at the body of roll at middle part and positioned at body of roll two ends；Countershaft include positioned at middle part the body of roll and Roll neck, bearing rib roll neck positioned at body of roll two ends.

The main shaft body of roll of the component of the roll includes 5 projections around the body of roll, and the countershaft body of roll includes 4 around the body of roll Individual projection；Countershaft surround groove of 4 projections of the body of roll with spindle collar between 5 projections of the body of roll and is meshed.

The main shaft roll neck of the component of the roll is located at the body of roll two ends, is connected by bearing rib roll neck with the body of roll；Axle Hold block roller neck has 25% radian to be connected with the body of roll；The countershaft roll neck of the component of the roll is located at the body of roll two ends, leads to Bearing rib roll neck is crossed with the body of roll to be connected；Bearing rib roll neck has 25% radian to be connected with the body of roll.

Above-mentioned technical proposal is employed, the utility model has following beneficial effect：

(1) the utility model product is meshed by the groove on the tooth and countershaft on main shaft, simple in construction, assembling side Just, job stability is high, improves the machining accuracy of roll, while making product reduce production cost, improves the production of roll Amount and quality.

(2) the bearing rib roll neck of the utility model product has 25% radian to be connected with the body of roll, has product higher Hardness, intensity and anti-wear performance etc..
