The invention is auger drive bearing mechanism having an upward auger device having a center shaft with an auger formed about and along the shaft and a sleeve surrounding the auger shaft and auger. A bearing housing is mounted at the lower end of the auger shaft and a housing shaft has its upper end connected to the auger shaft, while the housing shaft has it lower end adapted to be mounted to the power take off shaft of a tractor for powering the shaft and auger. A dual pair of tapered bearings are mounted in the housing on the housing shaft with one tapered bearing having rollers angled downward and outward to withstand the axial downward trust load of the auger and weight of grain and other particles when augered upward by the auger in the sleeve. An opposed tapered bearing at the lower end of the bearing housing acts to hold the housing mechanism together.
A auger drive mechanism for an upward inclined grain auger device having a center shaft with an auger surrounding the center shaft and a cylindrical sleeve surrounding the auger, said mechanism comprising a bearing drive housing mounted at the lower end of the auger shaft and a housing shaft in the housing detachably mounted at its upper end to the auger shaft, said housing shaft having its lower end adapted to be mounted to one joint of a universal connection with the other joint of the universal connection mounted to the power take off of a tractor, a dual pair of tapered bearings mounted in the housing on the housing shaft with one tapered bearing having rollers angled downward and outward to withstand the axial downward thrust load of the auger and the weight of the grain and other particles being augered upward by the auger in the auger sleeve, said other tapered bearing being at the lower end of the baring housing acting to hold the mechanism together.
An upward inclined auger device comprising an auger drive mechanism and an elongated forward upward inclined sleeve with an auger rotatably mounted in said sleeve, a housing at the lower end of said auger sleeve and a power shaft rotatably mounted in said housing having its upper end detachably mounted in said auger shaft and its lower end adapted to be mounted to a universal joint connection to a power take off of a tractor, dual tapered bearings mounted in said housing at the lower end of the inclined auger and sleeve, one of said tapered bearings having rollers rotatably mounted in a bearing housing mounted at the lower end of the sleeve at an upward lateral angle to the downward longitudinal axis of the auger to withstand the downward angular load of the auger along its longitudinal axis and withstand the load of particles being augered in an opposed upward angle along the longitudinal axis of the auger and sleeve, the other of said tapered bearings having rollers to hold the bearing assembly together in the housing.
