1. Description 37-1/2" rotary table consists of main frame, main barrel, main bearing, crown gear, pinion shaft assembly, locking device, top cover, lower race retainer, seals and oil level dip stick. The main frame is fabricated out of steel casting and steel plates. The oil reservoir is built in to provide lubricant for the bevel gear set and the bearings. The main barrel is a steel casting. It has an opening of 37-1/2". It is supported by the main bearing and retained in the main frame by the lower bearing retainer and hook bolts. The crown gear is mounted on the main barrel. The main bearing bears the downward load and the upward thrust exerted on the table. Shims are used to adjust the mounting distance of the crown gear. The pinion shaft assembly consists of the pinion, shaft, a cylindrical roller bearing, and a spherical roller bearing. These are mounted in the cast steel housing complete with bearing spacer, seal, seal sleeve and seal housing. The pinion shaft assembly is mounted inside the opening on the main frame. The proper mounting height of the crown gear is adjusted by using shims under the main bearing. The mounting distance of the pinion shaft assembly is adjusted by using shims between the pinion shaft assembly and the main frame. There are notches cast on the main barrel for locking the table. When the table lock is flipped to the locking position matching one of the notches, the table will be locked. Master bushings and inserts required are not supplied with the table. They must be ordered separately. 1.
