Abstract
Abstract A spindle support assembly in a glass plate edge grinding machine comprises a support member provided on a spindle for a grinding wheel through a bearing, a resilient member fixed to the outer portion of said support member, a holding member adapted to hold said resilient member from the outside thereof, a clamp member disposed between said support member and said holding member, and a friction member inserted between the lower face of said clamp member and the upper face of said resilient member axially opposite to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
236 words
A spindle support assembly in glass plate edge grinding machine comprising a cylindrical support member provided on a spindle for a grinding wheel through a bearing, an annular-shaped resilient member formed of elastic material of suitable elasticity, said resilient member being disposed in such a manner as the inner portion thereof is fitted to an annular groove formed on the outer portion of said cylindrical support member, a holder which holds said resilient member from the outside thereof, a clamp plug disposed between said cylindrical support member and said holder, the outer portion of said clamp plug being in threaded engagement with the inner portion of said holder, the inner face of said clamp plug being suitably spaced from the outer face of said cylindrical support member, a pressure ring having a tapered inside which is gradually enlarging towards the resilient member, said pressure ring being disposed in such a manner as said tapered inner face is in contact with the corresponding inclined face of said resilient member, and a friction ring inserted between the lower face of said clamp plug and the upper face of said resilient member axially opposite to each other, the inner face of said friction ring being in contact with the outer face of said cylindrical support member, the outer face thereof being spaced from the inner face of said holder to provide a floating space for said friction ring therebetween.
Claim 2
Dependent Claim
236 words
A spindle support assembly in glass plate edge grinding machine comprising a cylindrical support member provided on a spindle for a grinding wheel through a bearing, an annular-shaped resilient member formed of elastic material of suitable elasticity, said resilient member being disposed in such a manner as the inner portion thereof is fitted to an annular groove formed on the outer portion of said cylindrical support member, a holder which holds said resilient member from the outside thereof, a clamp plug disposed between said cylindrical support member and said holder, the outer portion of said clamp plug being in threaded engagement with the inner portion of said holder, the inner face of said clamp plug being suitably spaced from the outer face of said cylindrical support member, a pressure ring having a tapered inside which is gradually enlarging towards the resilient member, said pressure ring being disposed in such a manner as said tapered inner face is in contact with the corresponding inclined face of said resilient member, and a friction ring inserted between the lower face of said clamp plug and the upper face of said resilient member axially opposite to each other, the inner face of said friction ring being in contact with the outer face of said cylindrical support member, the outer face thereof being spaced from the inner face of said holder to provide a floating space for said friction ring therebetween.
Claim 3
Dependent Claim
146 words
A spindle support assembly in a glass plate edge grinding machine comprising a spindle, a support member rotatably supporting the spindle, a resilient member mounted on the outer portion of said support member, a holding member engaging said resilient member from the outside thereof, a clamp member mounted between said support member and said holding member for axial movement relative thereto, a pressure ring mounted between the clamp member and the resilient member and having a tapered inner surface engaging the resilient member, the pressure ring being movable axially by the clamp member whereby the resilient member is forced against the support member as the clamp member is moved toward the resilient member, and a friction ring mounted between the support member and the holding member, the friction ring having an inner periphery engaging the support member and an outer periphery spaced from the holding member.
Claim 4
Dependent Claim
146 words
A spindle support assembly in a glass plate edge grinding machine comprising a spindle, a support member rotatably supporting the spindle, a resilient member mounted on the outer portion of said support member, a holding member engaging said resilient member from the outside thereof, a clamp member mounted between said support member and said holding member for axial movement relative thereto, a pressure ring mounted between the clamp member and the resilient member and having a tapered inner surface engaging the resilient member, the pressure ring being movable axially by the clamp member whereby the resilient member is forced against the support member as the clamp member is moved toward the resilient member, and a friction ring mounted between the support member and the holding member, the friction ring having an inner periphery engaging the support member and an outer periphery spaced from the holding member.
Claim 5
Dependent Claim
25 words
The structure of claim 2 in which a portion of the resilient member has an inclined surface engaging the tapered surface of the pressure ring.
Claim 6
Dependent Claim
33 words
The structure of claim 2 in which said support member is cylindrical and is provided with an annular groove on the outer portion thereof, the resilient member being received in the annular groove.
Claim 7
Dependent Claim
22 words
The structure of claim 2 in which said support member is cylindrical and the inner periphery of the friction ring is circular.
