Arrangement for mounting a tubular elastomeric member onto a shaft member

An elastomeric tubular device for being mounted on a shaft member, comprising:

• a tubular sleeve member made of resiliently deformable elastomeric material and having an inner circumferential surface adapted to be fitted onto a shaft member;
• an annular projection extending inwardly and integrally from said inner circumferential surface of said tubular sleeve member;
• and
• an endless band made of relatively rigid material which has a uniform cross sectional shape over its entire circumferential length and disposed about said tubular sleeve member such that a portion of said tubular sleeve member is disposed coaxially between the endless band and said annular projection;
• an inner diameter of said annular projection being slightly smaller than an outer diameter of a portion of the shaft member engaged by said annular projection when said tubular sleeve member is mounted on the shaft member, and an inner diameter of said endless band being slightly larger than said outer diameter of said portion of the shaft member.

An arrangement for mounting a tubular member made of elastomeric material onto a rotatable shaft member such that the tubular member is prevented from moving in radial and axial directions relative to the shaft member, the arrangement comprising:

• a tubular sleeve member made of resiliently deformable elastomeric material and having an inner circumferential surface adapted to be fitted onto a shaft member;
• an annular projection formed integrally on a small portion of said inner circumferential surface of said tubular sleeve member;
• and
• an endless band made of relatively rigid material which has a uniform cross sectional shape over its entire circumferential length, said endless band being disposed with a small portion of said tubular sleeve member and said band coaxially surrounding said annular projection such that said small portion is disposed between the band and the projection;
• an inner diameter of said annular projection being slightly smaller than an outer diameter of the shaft member, and an inner diameter of said endless band being slightly larger than said outer diameter of the shaft member;
• and
• said annular projection is formed in an axial extension of said tubular sleeve member, and said endless band is adapted to be fitted onto said axial extension.

An elastomeric tubular device for being mounted on a shaft member, the device comprising:

• a tubular sleeve member made of resiliently deformable elastomeric material and having an inner circumferential surface adapted to be compressively fitted onto a shaft member;
• and
• an endless band made of relatively rigid material molded within said tubular sleeve member so as to coaxially surround a portion of said tubular sleeve member defining said inner circumferential surface;
• said inner circumferential surface of the tubular sleeve member having a diameter slightly smaller than an outer diameter of the shaft member, and the endless band having an inner diameter slightly larger than said outer diameter of the shaft member such that said endless band compresses said portion of the tubular sleeve member when the tubular sleeve member is compressively fitted onto the shaft member for thereby preventing the tubular member from moving in radial and axial directions relative to the shaft member.
