연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A grinding wheel for use in a skate blade sharpening system includes a metal grinding ring having an abrasive-coated outer surface for contacting a skate blade to be sharpened during sharpening, and a generally disk-shaped hub to which the grinding ring is fixedly mounted. The hub and grinding ring are configured for mating with an arbor on a rotating shaft of the skate blade sharpening system. Generally the hub is of a less expensive and lower-density material than the grinding ring. In one embodiment, the hub is of a lightweight material such as thermo...

1. A grinding wheel for use in a skate blade sharpening system, comprising: a grinding ring having an abrasive-coated outer surface for contacting a skate blade to be sharpened during sharpening;a generally disk-shaped hub to which the grinding ring is mounted, the hub and grinding ring being configured for mating with an arbor on a rotating shaft of the skate sharpening system and an outer cover attached to one axial face of the hub; andan electromagnetic identification tag retained between the outer cover and the hub. 2. A grinding wheel according to claim 1, wherein the abrasive-coated outer surface of the grinding ring comprises a hard coating. 3. A grinding wheel according to claim 1, wherein the mating is a heat-conducting mating by which heat generated in the grinding ring during the sharpening is conducted to the arbor. 4. A grinding wheel according to claim 3, wherein the heat-conducting mating includes a mating between a portion of an inner annular surface of the grinding ring and an annular outer rim of the arbor. 5. A grinding wheel according to claim 4, wherein the portion of the inner annular surface of the grinding ring is an annular portion at one axial end of the grinding ring extending beyond an axial end of the hub. 6. A grinding wheel according to claim 1, wherein the grinding ring has a diameter less than 100 mm. 7. A grinding wheel according to claim 6, wherein the grinding ring has a diameter of about 50 mm or less. 8. A grinding wheel according to claim 1, wherein the hub is of a material having a density less than a density of the grinding ring. 9. A grinding wheel according to claim 8, wherein the hub is of thermoplastic. 10. A grinding wheel according to claim 8, wherein radial thickness of the grinding ring is less than one-quarter of an outside radius of the grinding ring. 11. A grinding wheel according to claim 1, wherein the hub has a shallow cavity at one axial end in which the identification tag is disposed. 12. A grinding wheel according to claim 1, wherein the outer cover as an interference fit with the one axial face of the hub. 13. A skate blade sharpening system, comprising: a blade retention mechanism configured to securely hold a skate blade during a sharpening operation;a rotating shaft including an arbor;a grinding wheel mounted to the rotating shaft, the grinding wheel including (i) a metallic grinding ring having an abrasive-coated outer surface for contacting the skate blade during the sharpening operation, (ii) a generally disk-shaped hub to which the grinding ring is mounted, and (iii) an electromagnetic identification tag retained by the hub, the hub and grinding ring mating with the arbor; anda carriage assembly configured to move the grinding wheel along a lower profile of the skate blade during the sharpening operation. 14. A skate blade sharpening system according to claim 13, wherein the arbor includes radial vane features causing air flow about the arbor and the grinding ring for convective heat dissipation during the sharpening operation. 15. A skate blade sharpening system according to claim 13, wherein both the arbor and hub have shaped outer edges which mate with respective edges of the grinding ring, and wherein a mating between the arbor and grinding ring is a sliding contact mating that permits mounting and dismounting of the grinding wheel while also providing for heat transfer between the grinding ring and the arbor. 16. A skate blade sharpening system according to claim 15, wherein the mating is between a portion of an inner annular surface of the grinding ring and an annular outer rim of the arbor. 17. A skate blade sharpening system according to claim 16, wherein both the hub and arbor have respective shoulder portions on which respective portions of the grinding ring rest, such that a shoulder portion of the hub extends only partway into the grinding ring, and a remaining part of the grinding ring extends beyond an arbor-facing end of the hub and mates with the shoulder portion of the arbor. 18. A skate blade sharpening system according to claim 13, further including: a chassis having an elongated slot for receiving the skate blade;the carriage assembly including (1) a grinding wheel motor mounted on a motor arm, the motor arm configured for limited rotational motion on a horizontal motor arm spindle to impart corresponding limited arcuate vertical motion to the grinding wheel motor, and (2) an elongated spindle from which the rotating shaft extends, the spindle being coaxial with and mechanically coupled to a drive shaft of the motor. 19. A skate blade sharpening system according to claim 13, wherein the chassis has a frontward portion and a rearward portion, the rearward portion supporting the carriage assembly, the frontward portion having an elongated slot and supporting the blade retention mechanism. 20. A skate blade sharpening system according to claim 19, wherein the carriage assembly further includes a vertical limit adjustment mechanism configured and operative to set a maximum vertical position of the grinding wheel, the maximum vertical position being adjustable between (1) a first maximum vertical position allowing the grinding wheel to ride upward to a corresponding first vertical limit, and (2) a lower second maximum vertical position allowing the grinding wheel to ride upward to a corresponding lower second vertical limit. 21. A skate blade sharpening system according to claim 19, wherein the blade retention mechanism includes an opposed pair of clamp jaws at the bottom surface of the chassis. 22. A skate blade sharpening system according to claim 21, wherein the chassis further includes a jaw guard configured to contact the spindle when a skate blade is not present to prevent the grinding wheel from contacting the clamp jaws. 23. A skate blade sharpening system according to claim 19, wherein the carriage assembly further includes a Y-adjustment mechanism providing for alignment of the grinding wheel with the skate blade in a vertical plane, the Y-adjustment mechanism including a mechanism of the motor arm spindle causing translational movement of the motor arm in response to rotation of a spindle gear. 24. A skate blade sharpening system according to claim 23, wherein the Y-adjustment mechanism further includes an adjustment axle on which an adjustment knob is mounted, the adjustment axle having a gear engaging the spindle gear and being located below the motor arm spindle to enable a user to grasp and rotate the adjustment knob by reaching beneath the platform portion of the chassis. 25. A grinding wheel according to claim 1, wherein the outer cover is a tag capture disk. 26. A grinding wheel according to claim 1, wherein the outer cover is a graphic label.
