Problems solved by technology

While this seal reduces the amount of contamination and lost grease, the seal tends to add significant drag and significantly increases the power required to drive the large number of spindles on each drum
Previously, the increased power required by the seal was so high that the seal was impractical

Embodiment Construction

[0016] specific implementation plan

[0017] Such as figure 1 As shown, a spindle assembly 10 is shown which includes a barbed picking spindle 12 which rotates within a conventional spindle nut 14 about a spindle axis 12a. Spindle nut 14 is threaded and adapted to be mounted on an upright picker rod, a portion of which is indicated at 15 . Spindle 12 includes a bevel gear 16 adapted to cooperate with a similar bevel gear (not shown) supported for rotation within picking bar 15 . For further details on the picking bar assembly and drive arrangement reference can be made to US Patent No. 4,463,543 issued to Hubbard et al. and incorporated herein by reference.

[0018] Assembly 10 includes a first or inner bushing 18 which is press-fitted into a cylindrical bore 20 in shaft nut 14 ; Fitted into the bore 20 and offset axially outward from the outer end of the bushing 18 to define an annular cavity 20c surrounding the cylindrical journal region or shank 23 of the spindle 12; the...

Abstract

The present invention relates to a cotton picker spindle element with grease reservoir and a grease and dirt seal. The present invention relates to a spindle assembly including a spindle with a blind bore extending along the spindle axis from the drive gear towards the outer end to reduce spindle weight and providing a lubrication reservoir in the spindle. Cross-formed holes extend from the blind bore through to the bearing surface of the spindle. Lubricant from the spindle bars passes into the bore where it is stored and distributed to the journal areas through the small metering apertures. A very low friction seal between the outer bushing and dust collar is pressed into the spindle nut and seals against the polished chrome spindle surface. The seal allows a slight amount of lubricant passage outwardly from the bushings while limiting inward movement of dust towards the bushings.

Description

technical field [0001] This invention relates generally to cotton harvesters, and more particularly to spindles for cotton harvesters. Background technique [0002] A typical cotton picker includes a number of rotating barbed spindles that protrude into the plant. The cotton picking drum assembly consists of a plurality of upright picking bars, each supporting a row of rotatable picking spindles. Each spindle is elongated and includes a transmission mechanism that is driven to rotate the spindle about its main axis when the barbs engage the cotton. Cotton is wound on the spindle and is taken off from the spindle by a doffer mechanism. The doffer mechanism includes a plurality of flexible doffers, and each row of spindles corresponds to a doffer. Cotton harvesters typically consist of 2 to 6 front row units, each supporting a pair of upright picking drums with 12 to 16 picking bars. Each picking rod in turn rotatably supports up to twenty picking spindles. Several hundred...
