Crawler drive system
A drive assembly for a mining vehicle includes a frame, a housing coupled to the frame, and a motor positioned in the housing. The motor includes a motor frame with a first axial end and a second axial end opposite the first axial end. The drive assembly also includes a transmission that is positioned at least partially within the frame. The transmission is coupled to the motor frame at the first axial end. The drive assembly further includes a support assembly that couples the second axial end of the motor frame to the housing.
1. A drive assembly for a mining vehicle comprising:
a housing;
a motor positioned in the housing, the motor including a first axial end, a second axial end opposite the first axial end, and a standardized face plate at the first axial end;
a transmission having a standardized input face coupled to the standardized face plate of the motor; and
a support assembly coupling the second axial end of the motor to the housing.
2. The drive assembly of claim 1 , wherein the transmission is coupled to the motor with a direct shaft to shaft connection.
3. The drive assembly of claim 1 , wherein the motor includes an output shaft, wherein the housing includes a slot extending parallel to the output shaft, and wherein the support assembly includes a fastener that is received within the slot.
4. The drive assembly of claim 1 , wherein the support assembly suspends the second axial end of the motor from the housing.
5. The drive assembly of claim 1 , wherein the support assembly includes a mount with a yoke portion and a flange portion.
6. The drive assembly of claim 5 , wherein the yoke portion is coupled to the second axial end of the motor, and the flange portion is coupled to the housing.
7. The drive assembly of claim 1 , wherein the face plate is a first face plate, and wherein the motor further includes a second standardized face plate at the second axial end.
8. The drive assembly of claim 7 , wherein the first face plate has a different configuration than the second face plate.
9. The drive assembly of claim 8 , wherein the first face plate includes a NEMA D face and the second face plate includes a NEMA C face.
10. The drive assembly of claim 1 , wherein the support assembly includes an elastic member between the motor and the housing.
11. The drive assembly of claim 1 , wherein the support assembly is coupled to an upper support of the housing.
12. The drive assembly of claim 1 , wherein the support assembly is coupled to a lower support of the housing.
13. The drive assembly of claim 1 , wherein the transmission is positioned at least partially within a frame of a crawler leg.
14. The drive assembly of claim 13 , further comprising a crawler track extending around the frame.
15. The drive assembly of claim 1 , wherein the support assembly includes:
a mount including an upper flange portion and a lower yoke portion, the upper flange portion having an aperture and the lower yoke portion configured to be coupled to the second axial end of the motor;
a fastener extending through the aperture; and
a nut coupled to an end of the fastener, the nut being slidably receivable within a slot of the housing to couple the support assembly to the housing.
16. The drive assembly of claim 15 , further comprising an elastic member positioned between the flange portion and the nut.
