Background technique
The Machining centershorizontal main axis is horizontally disposed with, 3-5 coordinates are arranged, commonly three rectilinear coordinates add a rotation motion coordinate (rotary table), it can finish the processing of all the other four faces except that attachment face and end face after workpiece once is installed, therefore be very suitable for machining box-type workpieces.It can realize unapproachable precision of conventional equipment and quality requirement, so some required precision height, miscellaneous equipment can't reach the workpiece of its required precision, and particularly some space curved surfaces and complex-shaped workpiece are generally all considered to process on Machining centershorizontal.Therefore Machining centershorizontal is a kind of efficient, high-quality automated production equipment.
Machining centershorizontal is made up of transmission system, guide track system, hydraulic system and measuring system four systems.The B rotation shaft unit belongs to transmission system, mainly bears worktable rotation calibration, generally comprises thrust ball bearing with flat seat, solid of rotation and solid of rotation seat, and the body of solid of rotation and solid of rotation seat is respectively as the raceway up and down of thrust ball bearing with flat seat.See Fig. 1; the quantity of the ball hole in the cage ring of the thrust ball bearing with flat seat of existing Machining centershorizontal such as MC1210 Japan Machining centershorizontal is 12; diameter is 8mm; in the man-hour that adds of carrying out precision parts; because each ball pressure is bigger; make ball and bearing race heavy wear and distortion; can cause the thrust ball bearing with flat seat of no blowout patche, seat ring not have the effect of load-bearing; cause the friction that contacts of the upper-end surface of the lower end surface of solid of rotation and solid of rotation seat; make that indexing motor revolution electric current overcurrent causes reporting to the police, cause the frequent and shutdown of fault.And Machining centershorizontal costs an arm and a leg, and repairs or purchase again business economic pressure is increased.
The model utility content
The purpose of this utility model provides a kind of no blowout patche of slewing gear, the thrust ball bearing with flat seat of seat ring and B rotation shaft unit that comprises the Machining centershorizontal of this thrust ball bearing with flat seat of being used for.
The technological scheme that realizes the utility model purpose is: adopt a kind of novel thrust ball bearing with flat seat, it comprises ball and cage ring.Ball is 24, diameter 10mm.Ball hole in the cage ring is 24, and diameter is 10mm.The B rotation shaft unit that comprises above-mentioned thrust ball bearing with flat seat comprises thrust ball bearing with flat seat, solid of rotation and solid of rotation seat.The body of solid of rotation and solid of rotation seat is respectively as the last race member of thrust ball bearing with flat seat and following race member.The lower end surface of solid of rotation is provided with raceway.The upper-end surface of solid of rotation seat is provided with down raceway.Thrust ball bearing with flat seat comprises ball and cage ring.Cage ring is between solid of rotation and solid of rotation seat, and each ball is arranged in a corresponding ball hole of cage ring, and the outer surface of each ball rolls with the last raceway of the solid of rotation of top simultaneously and contacts and contact with the following raceway rolling of the rotation pedestal of below.Ball is 24, diameter 10mm.Ball hole in the cage ring is 24, and diameter is 10mm.The sectional shape of last raceway and following raceway is a circular arc, and the A/F of last raceway and following raceway is 5mm, and last raceway and following raceway (31) match with ball.
The utlity model has positive effect: (1) thrust ball bearing with flat seat of the present utility model has increased the quantity and the diameter of ball and ball hole, and the bearing power of the thrust ball bearing with flat seat of no blowout patche, seat ring is increased.(2) adopted the B rotation shaft unit of thrust ball bearing with flat seat of the present utility model, can not have because of the ball in the thrust ball bearing with flat seat after the less wearing and tearing promptly can't load-bearing, the friction and the lower end surface that causes solid of rotation contacts with the upper-end surface of solid of rotation seat, thus cause indexing motor revolution electric current overcurrent and report to the police.(3) the utility model is simple in structure, cost is low, has guaranteed that expensive Machining centershorizontal can normal, efficiently move, and has saved the cost of production of repairing or resetting.
