Abstract
A scribe saw head assembly is provided for a loin puller and has substantially reduced wear and increased life of the assembly components. A pinion assembly includes a pinion shaft and a thrust bearing. The shaft has a flange to support the thrust bearing, which is retained by a pair of retainers. The flange and thrust bearing provides constant contact between the pinion shaft and the standard of the scribe saw assembly, prevents side to side movement of the pinion shaft, and prevents longitudinal floating of the pinion shaft.
Claims11
A scribe saw assembly, comprising:
- a standard to drivingly support a scribe saw rotary blade;
- a rotary scribe saw blade mounted on the standard for cutting a carcass middle;
- a motor operatively connected to the blade for rotating the blade;
- a pinion gear and a bevel gear meshingly mounted in the standard, with the motor drivingly connected to the pinion gear and the blade drivingly connected to the bevel gear;
- a shaft interconnecting the pinion gear and the motor;
- a flange extending radially outward on the shaft.
A scribe saw head assembly for a loin puller machine, comprising:
- a standard adapted to drivingly support a scribe saw rotary blade;
- a pinion assembly including a pinion shaft with a pinion gear mounted on the pinion shaft;
- a motor drivingly connected to the pinion assembly;
- the pinion shaft having an outwardly extending flange;
- and
- a thrust bearing on the pinion shaft adjacent the flange.
A method of minimizing wear of a pinion assembly of a scribe saw, comprising:
- installing a bearing adjacent a radial flange on a shaft of the pinion assembly to substantially eliminate longitudinal float of the shaft.
