Fig. 5 is discussed now, and Fig. 5 represents the chart of the difference between embodiment of the present utility model and the at present commercially available ball.Be described in more detail below these balls.Numerical value on the Y-axis of the left side is the initial velocity of ball when hitting the bar test with length.Each ball hits bar and impacts the lower Nike SQ that adopts 9.5 lofts of the same terms (bar head speed, impact angle etc.) is long.
Height by each bar shaped on the bar chart among the figure represents initial velocity.Initial velocity represents with miles per hour shown in the bar chart.Initial velocity 150 miles per hours approximate 220 feet per seconds.Initial velocity approximately 170 miles per hours approximates 250 feet per seconds.
The numeric representation ball on the right is made the as a whole coefficient of resilience in the chart.In order to measure the coefficient of resilience of object, with the initial velocity ejaculation object of air bubble with about 40 metre per second (m/s)s.Steel plate is positioned at apart from about 1.2 meters of big gun, about 0.6 to 0.9 meter apart from big gun of speed mointor.Object is penetrated by air bubble, and the Negotiation speed supervising device, to determine initial velocity.Afterwards, object strikes is to steel plate, and the Negotiation speed supervising device that rebounds, to determine return speed.The coefficient of resilience is the ratio of return speed and initial velocity.The coefficient of resilience of each ball is by line 544 expressions in the chart.
X-axis represents test ball.Each test ball test initial velocity and coefficient of
resilience.Front 9 balls (label 1-9) are commercially available golf.These balls all have the ball sandwich layer that is about 40mm by the diameter of butadiene rubber compound preparation.For each ball, the definite prescription of ball sandwich layer is slightly different.The ball sandwich layer of each ball is prepared to have the different degrees of compression and the coefficient of resilience by the butadiene rubber with different additive or different size.It is believed that to have association between the coefficient of resilience and the ball sandwich layer size, may be very strong association, so the minor variations of ball sandwich layer size can be brought very important impact to the coefficient of resilience.The about 1.4mm in the top layer of each ball is thick and mainly by SURLYN
Preparation.
On the other hand, the ball of label 10 is the balls according to the utility model embodiment preparation.Be different from front 9 balls, the ball of label 10 has the diameter of mainly being made by the fluoropolymer resin of highly neutralization to be about the ball sandwich layer of 38mm.The diameter of ball sandwich layer can arrive greatly approximately 41mm.The top layer of ball approximately 2.1mm is thick, but can be as small as the approximately thickness of 0.9mm.If necessary, can also comprise cover layer, meet the USGA minimum dimension regulation of 42.67mm (1.680 feet) to guarantee ball.
During the concerning of contrast initial velocity and the coefficient of resilience, it should be noted, for ball 1-9, population interconnection between the coefficient of resilience and the initial velocity.For example, for ball 1,2,4 and 5, its coefficient of resilience is less than 0.795, and initial velocity drops to and is lower than approximately 150.2.For ball 3,6,7 and 8, its coefficient of resilience is greater than 0.800, and initial velocity is greater than approximately 150.8.For ball 9, its coefficient of resilience is about 0.800, and initial velocity is about 150.8.Therefore, a kind of population interconnection between the graphical presentation coefficient of resilience and the initial velocity.
But chart display ball 10 initial velocities shown in Figure 5 depart from the expection initial velocity of traditional ball, and its coefficient of resilience is 0.774.For ball 10, coefficient of resilience value is about 0.774.Be different from by the initial velocity below 150 miles per hours of traditional ball 1-9 prediction, the initial velocity of ball 10 still keeps 150.8, and itself and the coefficient of resilience are almost identical far above the initial velocity of the ball of ball 10.Therefore, by adopting above-mentioned spherical structure, quarter butt can keep relatively low better feel and the rotatory of obtaining than the coefficient of resilience of ball in play, keeps simultaneously sufficiently high initial velocity and obtains long remote when hitting bar and impacting.
This impacts particular importance for half wedge.Have the ball of the low coefficient of resilience, the linksman often more firmly impacts ball, for example, adopts higher bar head speed, obtains the distance identical with the ball with higher coefficient of resilience.More firmly impact (bar head speed is larger), give revolution of basketball the more.Therefore, the linksman can make the lower ball of the coefficient of resilience that good initial velocity is arranged and hit distance, but has increased rotatory in the quarter butt match.
The additional features that can contrast between existing ball and the disclosed ball of the utility model can be referring to Fig. 6.Fig. 6 is the different balls of expression and the degree of compression of ball sandwich layer and the chart of the relation between the coefficient of resilience.The degree of compression of the endosphere sandwich layer of the value representation ball on the X-axis.The degree of compression is by the mensuration of mode well known in the art.Spherical ball sandwich layer and/or ball place under the initial load 10KG.On one or more points, for example on limit, seam or random point, measure the measured value of bulb diameter, usually in millimeter.Record single value or mean value.Load is increased to 130KG, measures the second measured value of bulb diameter at same point, still in millimeter.Record single value or mean value under the heavy load more.Difference between record value is the degree of compression, in millimeter.
The coefficient of resilience of four kinds of situations that the value representation on the Y-axis is considered.Line 650 expression diameters are about 38mm and by the degree of compression of the ball sandwich layer of butadiene rubber compound preparation and the relation between the coefficient of resilience.The Trendline equation of this ball sandwich layer is expressed from the next
Y=0.7531-0.0128x
2+ 0.055x equation 1
Wherein x represents inner spherical core layer compression degree, and y represents the corresponding coefficient of resilience.
The degree of compression of line 660 expression balls and the relation between the coefficient of resilience, described bag is drawn together the top layer that covers the ball sandwich layer shown in the line 650.The equation of this Trendline is expressed from the next
Y=0.6794 – 0.0179x
2+ 0.0831x equation 2
Wherein x represents the ball sandwich layer degree of compression, and y represents the coefficient of resilience of ball as a whole.The difference of the relative coefficient of resilience of ball sandwich layer and the coefficient of resilience of ball is between approximately 0.035 to approximately between 0.037 the scope.
But, comprise that the contrast table of the relative coefficient of resilience of the ball of ball sandwich layer main or that prepared by the polymer of highly neutralization fully reveals obvious difference.Line 670 expression diameters are about 38mm and the degree of compression of ball sandwich layer main or that prepared by the polymer of highly neutralization fully and the relation between the coefficient of resilience.The equation of this Trendline is expressed from the next
Y=0.7951 – 0.0121x
2+ 0.0416x equation 3
Wherein x represents the ball sandwich layer degree of compression, and y represents the corresponding coefficient of resilience.
The degree of compression of line 680 expression balls and the relation between the coefficient of resilience, described bag is drawn together the top layer that covers the ball sandwich layer shown in the line 670.Described top layer has identical surface structure with the top layer of the ball shown in the line 650.The equation of this Trendline is expressed from the next
Y=0.6511 – 0.024x
2+ 0.1165x equation 4
Wherein x represents the ball sandwich layer degree of compression, and y represents the coefficient of resilience of ball as a whole.The difference of the relative coefficient of resilience of ball sandwich layer and the coefficient of resilience of ball is between approximately between 0.026 to 0.031 the scope.
Therefore, clearly show such as Fig. 6, for given inner spherical core layer compression degree, the ball with ball sandwich layer is compared with the ball with HNP ball sandwich layer has the lower coefficient of resilience.Similarly, in order to obtain the optimum efficiency of padded coaming, the difference of the coefficient of resilience of ball sandwich layer and the coefficient of resilience of ball is at least 0.026, but can significantly increase, such as 0.037,0.05,0.1 or higher.The coefficient of resilience of ball is lower, and ball more easily rotates, thus need to have the ball of the difference of the higher coefficient of resilience, such as at least 0.037 or 0.05.The relatively high coefficient of resilience of above-mentioned ball sandwich layer according to the utility model preparation allows when the option table layer material very large flexibility is arranged, because the coefficient of resilience of ball when padded coaming is provided as a whole still can be in the scope of optimum performance.
These beneficial effects are more simply expression in Fig. 7, and wherein for the given coefficient of resilience, ball sandwich layer Trendline 762 is compared with HNP ball sandwich layer Trendline 760 and shown all the time the lower ball sandwich layer degree of compression.HNP ball sandwich layer Trendline 764(has the Trendline of the complete ball of NHP ball sandwich layer) as a reference.
Therefore, replacing the ball sandwich layer with identical specific coefficient of resilience with the resin balls sandwich layer with specific coefficient of resilience allows the relative coefficient of resilience of ball and ball sandwich layer to have very big-difference.Especially the coefficient of resilience that surpasses the coefficient of resilience that ball sandwich layer Trendline provides and described ball when the coefficient of resilience of resin balls sandwich layer is during less than the given coefficient of resilience of following equation
Y=-0.0103x+0.8419 equation 5
Wherein y represents the coefficient of resilience, and x represents inner spherical core layer compression degree.
This can realize by preparing at least one inside/non-top layer by the ionomer/polymer that highly neutralizes usually.Surface features need to not change between the polymer drops sandwich layer of butadiene rubber ball sandwich layer and highly neutralization.But when using the polymer drops sandwich layer of highly neutralization, the difference of the coefficient of resilience of ball sandwich layer and ball is at least about 0.004.This allows to have the ball of the higher coefficient of resilience by identical skin-material preparation.
When following above-mentioned polymer drops sandwich layer for highly neutralization and during by the coefficient of resilience Trendline of the ball of the polymer drops sandwich layer preparation of neutralization highly, may needing in accordance with other restrictions.For example, qualified ball has the coefficient of resilience less than the given trend of equation 5, perhaps more conservatively, has the coefficient of resilience of the trend that provides less than following equation
Y=-0.0103x+0.8299 equation 6
Wherein y represents the coefficient of resilience, and x represents inner spherical core layer compression degree.Therefore, the designer may need to the fixed upper limit of the coefficient of resilience of the ball of following equation 4, so that the coefficient of resilience can not exceed the coefficient of resilience that equation 6 provides.
Can believe the character that the ball by the preparation of above-mentioned disclosure is improved.Can believe that described ball compares with expection and have higher initial velocity.Described ball also can allow to adopt a greater variety of skin-materials, especially comprises the material of those lower costs.Compare with other balls, described ball can be the linksman and provides than long running track and the lower ball of cost.
Optional layered articles structure also may strengthen these beneficial effects.For example, can according to instruction of the present utility model and the applying date be Augusts 20 in 2010 day, be called " golf (Golf Ball Having Layers with Specified Moduli and Hardnesses) with layer of regulation modulus and hardness ", application number is 12/860, goods described in 785 the U.S. Patent application are made golf, and the full content of this patent application is to be incorporated into this with reference to the mode of quoting.
Although described various embodiment of the present utility model, but specification is intended to as example, rather than restriction, and for this area those skilled in the art, it is apparent that more embodiment and embodiment can also be arranged in the utility model scope.Therefore, the utility model is only limited by the claims.In addition, in the claim scope, can make various changes and conversion.
