Abstract
An axle driving apparatus having a shaft sealing device to provide for compact and flexible packaging. The shaft sealing device includes an oil seal and a seal carrier for supporting the oil seal. The shaft sealing device can be used to provide a reliable fluid-tight seal for the axles and other shafts, thereby allowing the axles and other shafts to be located in different planes, and offset from the plane of the casing junction surface. The shaft sealing device may alternatively be configured as an integral unit that includes a shaft support.
Claims39
An axle driving apparatus, comprising:
- first and second casing sections joined along a junction surface to form a casing, wherein the junction surface of said first and said second casing sections lies in a first plane;
- a transmission housed within said casing;
- an axle having a longitudinal axis disposed within one of said first and second casing sections and having a longitudinal axis which lies in a second plane different from said first plane;
- an axle supporting means disposed within said one of said casing sections in which said axle is disposed;
- a seal carrier disposed between said axle and said casing;
- means for supporting said axle supporting means projecting from one of said first and second casing sections which is opposite to the casing section in which said axle is disposed, to support said axle supporting means;
- and
- an oil seal disposed around said axle and fixed within said seal carrier, said oil seal configured to provide a fluid-tight seal around said axle.
An axle driving apparatus, comprising:
- first and second casing sections joined along a junction surface to form a casing, wherein the junction surface of said first and said second casing sections lies in a first plane;
- an axle disposed within one of said first and second casing sections and having a longitudinal axis which lies in a second plane different from said first plane;
- a transmission housed within said casing;
- a seal supporting device and axle supporting device which are integral with each other and which are disposed within said casing between said axle and said casing.
An axle driving apparatus, comprising:
- first and second casing sections joined along a junction surface to form a casing, wherein the junction surface of said first and second casing sections lies in a first plane;
- a transmission housed within said casing;
- an axle disposed within one of said first and second casing sections and having a longitudinal axis which lies in a second plane different from said first plane and wherein said one of said first and second casing sections in which said axle is disposed is open with respect to the other casing section along the substantial length of the portion of said casing section in which said axle is disposed;
- axle supporting means disposed within said casing for supporting said axle, and
- a sealing member disposed between said first and second casing sections at said junction surface, said sealing member providing a fluid-tight seal around said axle.
An axle driving apparatus, comprising:
