Gear Processing industry increasingly competitive, for improving competitiveness, the working ability of numerical control horizontal gear hobbing machine bed is had higher requirement by user, satisfied high accuracy process it is also desirable to significantly improve working (machining) efficiency. And existing numerical control horizontal gear hobbing machine work spindle meets the general speed not high (within the 150r/min that is everlasting) of high accuracy transmission, meet high speed and super precision operating generally rigid not, it is impossible to meet efficiently high-precision processing request simultaneously.
And the work spindle front support of existing lathe is generally adopted sliding bearing or plain bearing, when pretension is big, caloric value is higher, less stable, it is necessary to adopt oil lubrication of fixed place and time, and structure is complicated, needs timed maintenance.
Summary of the invention
This utility model is low for working (machining) efficiency in prior art, the shortcoming of poor stability, it is provided that a kind of working (machining) efficiency is high, the gear-hobbing machine workpiece spindle device stablized.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:
Gear-hobbing machine workpiece spindle device, including bearing block and the work spindle being located in bearing block, also include the double-row conical bearing being located between work spindle and bearing block and the locking nut being located at double-row conical bearing side, work spindle is provided with the screw thread coordinated with locking nut, double-row conical bearing includes multiple ball, and ball is provided with axially extending bore. Raceway on the inside and outside circle of double-row conical bearing and ball fit tightly, ensure that ball rotates simultaneously, owing to being small-angle raceway, the power acting on interior raceway side seat during ball moving is greatly reduced, and therefore kinetic stability is high, and caloric value is little, only need to adopting grease lubrication, the later stage does not need to safeguard, the through hole in ball, enhance the antivibration of ball and absorb impact capacity, improve the ability of the interrupted cut processing of gear.
As preferably, being provided with the spacer ring being enclosed within work spindle between double-row conical bearing, between locking nut and double-row conical bearing, it is provided with the packing ring being enclosed within work spindle.When double-row conical bearing operates, the position of taper roll bearing is stablized by spacer ring, axial force is avoided to make taper roll bearing generation relative movement, reduction work spindle adds precision during work gear, packing ring is used for fixing double-row conical bearing and nut, prevent double-row conical bearing to be displaced outwardly when working, prevent nut loosening simultaneously.
As preferably, also include the inner end cap and the outer end cap that are located at double-row conical bearing opposite side, sealing ring it is provided with between inner end cap and outer end cap, sealing ring engagement sleeves is on work spindle, bearing block is located at the side of inner end cap, outer end cap is located at the opposite side of inner end cap, and outer end cap, inner end cap and bearing block are bolted to connection. Position by the fixing double-row conical bearing of interior outer end cap and work spindle, avoid external dust to contact with double-row conical bearing simultaneously, reduce the operating accuracy of double-row conical bearing, easy to assembly, reliability is high, compare existing machine tool structure and saved installation time, alleviate the workload of assembly crewman.
As preferably, the outside of outer end cap is provided with dust cap, and work spindle one end is provided with annular groove, and dust cap cooperation is embedded in annular groove. Dust cap ensures work spindle energy normal operation, is located in annular groove to be easy to the position of fixing dust cap, it is to avoid cause that dust cap is shifted over during work spindle operating.
This utility model is owing to have employed above technical scheme, there is significant technique effect: the raceway on the inside and outside circle of double-row conical bearing and ball fit tightly, ensure that ball rotates simultaneously, owing to being small-angle raceway, the power acting on interior raceway side seat during ball moving reduces, improve the stability of work spindle operating, and the caloric value of work spindle is little, only need to adopt grease lubrication, later stage does not need to safeguard, through hole on ball, enhances the antivibration of ball and absorbs impact capacity, improves the ability of the interrupted cut processing of gear.
