Abstract

A mounting and support mechanism for a rotary feeder gear motor having an adjusting housing, wherein the adjusting housing includes a support flange adjacent the gear motor, a hollow adjusting housing and a support flange adjacent a stationary feeder end cover. Contained within the adjusting housing is a carrier extension wherein the carrier extension at one end encases a stationary bushing, the stationary bushing houses an adjusting shaft to provide movement of a rotor assembly axially, and at the opposite end the carrier extension connects to a bearing carrier mechanism.

First claim

What is claimed is:

1. An adjustment assembly for axially adjusting a rotor in a rotary feeder comprising:
a housing having a first end distally disposed from a second end;
a carrier extension disposed within the housing, the carrier extension having a bearing end distally disposed from an adjustment shaft end, wherein the carrier extension is configured to slide axially within the housing, and wherein the adjustment end has areas defining a center opening;
a bearing carrier disposed within the housing adjacent to the bearing end of the carrier extension, wherein the bearing carrier is disposed at the first end of the housing, wherein the bearing carrier is configured to slide axially within the housing, and wherein the bearing carrier supports a first thrust bearing configured to engage a shaft connected to a rotor disposed in a rotary feeder;
a stationary bushing disposed in the center opening of the adjustment shaft end, wherein an inner wall of the stationary bearing is threaded;
a second thrust bearing disposed within the housing at the second end;
an adjusting shaft having a threaded end, a motor end distally disposed from the threaded end, and a body extending between the threaded end and the motor end, wherein the threaded end is disposed within the stationary bearing, wherein the motor end is configured to engage a motor, and wherein the body extends through the second thrust bearing.

2. The adjustment assembly of claim 1 further comprising the motor engaged to the second end of the housing, wherein the motor is configured to rotate the adjusting shaft.

3. The adjustment assembly of claim 2 , wherein the thread end of the adjustment shaft is threadedly engaged to the inner wall of the stationary bearing, and wherein the threads transform a rotational movement of the adjustment shaft into an axial movement of the carrier extension.

4. The adjustment assembly of claim 3 , wherein the carrier extension is engaged to the bearing carrier and wherein the bearing carrier transfers the axial movement of the carrier extension to the first thrust bearing.

5. The adjustment assembly of claim 4 further comprising the shaft connected to a rotor disposed in a rotary feeder, wherein the shaft has a shaft end disposed through the first thrust bearing such that that shaft is configured to rotate freely within the first thrust bearing, and wherein the first thrust beading transfers the axial movement from the bearing carrier into the shaft, thereby configuring the adjustment assembly to axially adjust the rotor in the rotary feeder.

6. The adjustment assembly of claim 1 , wherein the first end of the housing engages a stationary support flange of a side of the rotary feeder.

7. The adjustment assembly of claim 1 , wherein the second end of housing further comprises a thrust bearing housing, and a motor engaged to the second end of the housing.

8. The adjustment assembly of claim 1 , wherein the carrier extension comprises a material selected from the group consisting of: carbon, stainless steel, or a composite material.

9. The adjustment assembly of claim 1 , wherein the stationary bushing further comprises annular flanges disposed at opposite ends of the stationary bushing, wherein the annular flanges seat the adjusting shaft within the carrier extension.

10. The adjustment assembly of claim 1 , wherein the housing is coaxial with the rotor.

11. An adjustment assembly for axially adjusting a rotor in a rotary feeder comprising:
a housing having a first end distally disposed from a second end;
a carrier extension disposed within the housing, the carrier extension having a bearing end distally disposed from an adjustment shaft end, wherein the carrier extension is configured to slide axially within the housing, and wherein the adjustment end has areas defining a center opening;
a bearing carrier disposed within the housing engaged to the bearing end of the carrier extension, wherein the bearing carrier is disposed at the first end of the housing, wherein the bearing carrier is configured to slide axially within the housing, wherein the bearing carrier has a thrust bearing support configured to engage a first thrust bearing, such that the thrust bearing slides axially with the bearing carrier and such that the thrust bearing is freely rotatable within the thrust bearing support;
a stationary bushing disposed in the center opening of the adjustment shaft end of the carrier extension, wherein an inner wall of the stationary bearing is threaded and wherein an outer wall of the stationary bearing is fixedly engaged to the carrier extension.

12. The assembly of claim 11 further comprising an adjusting shaft having a threaded end, a motor end distally disposed from the threaded end, and a body extending between the threaded end and the motor end, wherein the threaded end is disposed within the stationary bearing, wherein the motor end is configured to engage a motor.

13. The assembly of claim 12 , further comprising a motor engaged to the second end of the housing, wherein the motor engages the motor end of the adjusting shaft.

14. The assembly of claim 13 further comprising a computer configured to activate the motor to adjust an axial position of a shaft connected to a rotor in a rotary feeder.

15. The assembly of claim 13 , further comprising a second thrust bearing disposed within the housing at the second end, wherein the body of the adjusting shaft extends through the second thrust bearing.

16. The adjustment assembly of claim 15 , wherein the second end of housing further comprises a thrust bearing housing, and wherein the second thrust bearing is disposed within the thrust bearing housing.

17. The assembly of claim 11 , wherein the housing is cylindrical and wherein the housing assembly encloses the carrier extension, bearing carrier, and first thrust bearing.

18. The assembly of claim 17 , wherein the carrier extension and bearing carrier and cylindrical.

19. The adjustment assembly of claim 11 , wherein the carrier extension comprises a material selected from the group consisting of: carbon, stainless steel, or a composite material.

20. The adjustment assembly of claim 11 , wherein the stationary bushing further comprises annular flanges disposed at opposite ends of the stationary bushing, wherein the annular flanges seat the adjusting shaft within the carrier extension.
