摘要:
A golf ball kit having an abrasive material adapted for imparting enhanced micro surface roughness to an exterior surface of a golf ball. The enhanced micro surface roughening affects the aerodynamic properties of the ball as compared to golf balls having the same set of construction specifications but without enhanced micro surface roughness. The kit includes an instruction device having a plurality of correlations between at least one performance parameter and micro surface roughness for at least a first golf ball.
摘要:
A method for match lapping a ball valve assembly including a ball and a seat, the method having the following steps: contacting the seat with the ball; rotating the ball about a first rotational axis; rotating the seat about a second rotational axis; and changing an angle formed at the intersection of the first and second rotational axes. The method may include applying lapping compound to one or both of the seat and ball.

A steel ball machining apparatus comprises a ball machining mechanism having a pair of machining plates which are adapted to oppose and rotate relative to each other, a steel ball storing vessel for supplying to and receiving from said polishing mechanism steel balls, a steel ball supply path provided between said machining mechanism and said steel ball storing vessel, a steel ball discharge path provided between said machining mechanism and said steel ball storing vessel adapted to discharge said steel balls to said vessel, and a set of parallel bars provided in at least one of said steel supply path and steel ball discharge path so as to eliminate foreign matter.
摘要:
A method of grinding rough-shaped spherical objects to a finished spherical form comprising the steps of freely supporting the rough-shaped spherical object on one end of a vertically oriented tube. This one end is open and has an inside diameter such that a segment portion of the object lies within the tube. Next, an abrasive is applied to the surface of the object, and the object is ground by vibrating the tube axially at a frequency in the range of approximatelly 20-25 KHz, whereby the surface of the object is ground to a truer spherical shape.
摘要:
Granular solid particles, in particular hard, comminuted material of any given shape, are kept continuously in relative movement in a funnel-shaped container by means of a stream of liquid whereby they are rounded off. The rounded-off particles are suitable as filler material for wear-resistant coatings.

THIS APPARATUS INCLUDES A ROTATABLE BALL SUPPORT MEMBER, A ROTATABLE BALL ENGAGING MEMBER POSITIONABLE DIRECTLY ABOVE THE BALL SUPPORT MEMBER AND MEANS FOR DRIVING THE BALL ENGAGING MEMBER. OTHER MEANS POSITION THE BALL ENGAGING MEMBER FOR MOVEMENT TO AND FROM ENGAGEMENT WITH THE BALL ON THE BALL SUPPORT MEMBER, A CUTTER MEANS IS PROVIDED AND A SUPPORT MEANS CARRIES THE CUTTER MEANS IN A PIVOTALLY POSITIONED SO THAT CONTROL MEANS CONNECTING TO THE SUPPORT MEANS CAN MOVE IT TO BRING THE CUTTER MEANS INTO AND OUT OF ENGAGEMENT WITH THEN THE FALL BACK SPEED OF A CONVEYED SUBSTANCES ON THE FLASH, OR RIND THEREFROM.
摘要:
A method of treating bearing rolling elements or bearing rings after a hardening and temper heat treatment is disclosed. The method may include treating the bearing rolling elements in a tumbling treatment and then in a duplex hardening treatment. The method may include treating the bearing rings in a peening treatment and then in a duplex hardening treatment. The duplex hardening treatment may also include at least one sequential process segment consisting of subjecting the bearing rolling element & rings to a nitriding process to increase the surface hardness and compressive residual stress. The combined two-step process produces a deep surface/sub-surface residual stress greater than the depth of the maximum operating von-Mises shear stress along with an ultra-hard surface with high magnitude of compressive residual stress. In so doing, the bearing ring and rolling elements will have significantly enhanced rolling contact fatigue resistance and resistance to surface imperfections and debris.
