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 adjusting housing assembly for a mounting and support mechanism for a rotary feeder adjusting mechanism of a rotary feeder comprising:
a rotary gear motor, an adjusting shaft, a stationary bushing, and a bearing carrier mechanism;
wherein a support flange is attached to the rotary feeder gear motor end of the rotary feeder;
a stationary feeder support flange adjacent a stationary feeder end cover of the rotary feeder;
a hollow adjusting housing extending between the support flange and the stationary feeder support flange, further comprising an adjusting shaft and a carrier extension.

2. The adjusting housing assembly of claim 1 wherein the stationary feeder support flange and the support flange may each have bolts to secure the flanges to the rotary feeder stationary feeder end cover and the rotary feeder gear motor respectively.

3. The adjusting housing assembly of claim 1 wherein the bearing carrier mechanism allows a rotor to move axially inside the hollow adjusting housing.

4. The adjusting housing assembly of claim 1 wherein hollow adjusting housing may be cylindrical or of a similar shape so as to encase the adjusting shaft, the adjusting shaft extending from the support flange to the stationary feeder support flange.

5. The adjusting housing assembly of claim 1 wherein the hollow adjusting housing further comprises a gear motor, external to the hollow adjusting housing, mounted to a first end of the hollow adjusting housing, the adjusting shaft enclosed by the hollow adjusting housing, a rotor coupling between the adjusting shaft and a first end of a cylindrical pocketed rotor of the rotary feeder.

6. The adjusting housing assembly of claim 1 wherein the hollow adjusting housing having a cylindrical sidewall connected at one end to a stationary feeder end cover of the rotary feeder and a support flange at an opposite end of the sidewall.

7. The adjusting housing assembly of claim 6 wherein the support flange supports a rotary feeder gear motor that rotates the adjusting shaft.

8. The adjusting housing assembly of claim 1 wherein the carrier extension at one end encases the threaded, stationary bushing.

9. The adjusting housing assembly of claim 8 wherein the adjusting shaft engages the threaded, stationary bushing and causes the carrier extension and the rotor assembly to which the carrier extension is attached to move axially.

10. The adjusting housing assembly of claim 9 wherein the carrier extension is sized such that the adjusting shaft is allowed to thread through and between the stationary bushing and a bearing carrier mechanism.
