Abstract
A transmission series has a first transmission and a second transmission. The first transmission and the second transmission each have a respective input shaft, a housing, a supporting structure fixed in the housing, and at least two bearings by means of which the input shaft is mounted rotatably in the respective supporting structure. The at least two bearings of the first transmission are of the same first design and the at least two bearings of the second transmission are of the same second design that is different from the first design. The supporting structures of the first and second transmissions are designed identically.
Claims12
Transmission series with a first transmission (101) and a second transmission (201), wherein the first transmission (101) and the second transmission (201) each have a respective input shaft (103, 203), a housing (105, 205), a supporting structure (107, 207) fixed in the housing and at least two bearings (109a, 109b, 209a, 209b) by means of which, respectively, the input shafts (103, 203) are mounted rotatably in the supporting structure (107, 207), and wherein the at least two bearings (109a, 109b) of the first transmission (101) and the at least two bearings (209a, 209b) of the second transmission (201) are, respectively, each of identical design;
- characterized in that
- the design of the at least two bearings of the first transmission (101) differs from the design of the at least two bearings (209a, 209b) of the second transmission (201);
- whereas
- the supporting structures (107, 207) are of identical design.
Transmission series according to either of the preceding claims;
- characterized in that
- the at least two bearings (109a, 109b) of the first transmission (101) are configured in an X-arrangement and the at least two bearings (209a, 209b) of the second transmission (201) are configured in an O-arrangement.
Transmission series according to any of the preceding claims;
- characterized in that
- the first transmission (101) and the second transmission (201) each have a respective cover (111, 211) which is fixed in the respective supporting structure (1007, 207) and through which the respective input shaft (103, 203) extends;
- and the cover (111) of the first transmission (101) and the cover (211) of the second transmission (201) are of identical design.
Transmission series according to the preceding claim;
- characterized in that
- the cover (111) of the first transmission (101) axially supports an outer ring of a first bearing (109a) of the first transmission (101).
Transmission series according to any of the preceding claims;
- characterized in that
- the supporting structure (207) of the second transmission (201) is provided with a step (213) which axially supports an outer ring of a first bearing (209a) of the second transmission (201).
Transmission series according to any of the preceding claims;
- characterized in that
- the input shaft (103) of the first transmission (101) is provided with a step (115) which axially supports an inner ring of the first bearing (109a) of the first transmission (101).
Transmission series according to any of the preceding claims;
- characterized in that
- an adjusting nut (113) screwed onto the input shaft (203) of the second transmission (201) axially supports an inner ring of the first bearing (209a) of the second transmission (201).
Transmission series according to any of the preceding claims;
- characterized in that
- the supporting structure (107) of the first transmission (101) has a groove (117) into which a locking ring (119) is set, such that
- the locking ring (119) axially supports an outer ring of a second bearing (109b) of the first transmission (101).
Transmission series according to any of the preceding claims;
- characterized in that
- the supporting structure of the second transmission (201) is provided with a step (119, 219) which axially supports an outer ring of a second bearing (209ba) of the second transmission (201).
Transmission series according to any of the preceding claims;
- characterized in that
- the input shaft (103) of the first transmission (101) is provided with a step which axially supports an inner ring of the second bearing (109b) of the first transmission (101).
Transmission series according to any of the preceding claims;
- characterized in that
- the input shaft (203) of the second transmission (201) is provided with a step (220) which axially supports an inner ring of the second bearing (209b) of the second transmission.
