BorgWarner Inc. - Auburn Hills MI

International Classification:

F16H061/04
F16H061/12

US Classification:

474 39, 474 14, 474 26, 474 37

Abstract:

A continuously variable belt drive system includes a driving pulley assembly, a driven pulley assembly and a V-shaped belt engaged to transfer rotary power therebetween. The driven pulley assembly includes a ratio adjustment mechanism that adjusts the position of a rear sheave relative to a forward sheave. The adjustment mechanism includes a motor and a worm gear mechanism that rotates an actuation screw. Rotation of the actuation screw is reacted by a split nut that translates the screw rotates along the axis of the driven pulley assembly. In one feature, the driven pulley assembly includes a fail-safe mechanism that operates when power is supplied to the motor to hold the split nut together. In another aspect of the invention, the driving pulley assembly includes a belt tensioning mechanism that maintains proper belt tension at all speeds and drive ratios.

Abstract:

A machine for folding and applying onserts onto consumer goods such as cigarette packs comprises a continuous roll of preprinted onserts and a transverse cutter assembly for cutting onsert segments from the continuous roll. Each onsert segment includes a pair of side-by-side preprinted onserts. A buckle folder receives each cut onsert segment and folds that segment along at least one transverse fold line. A longitudinal cutter assembly longitudinally cuts each folded onsert segment into two individual onserts. A transport system serially receives the individual folded onserts and moves the onserts along dual diverging paths where a pair of spaced apart lug belt conveyors receives the onserts from the discharge end of the transport system. Each lug belt conveyor includes spaced apart transverse lugs along the length thereof against which the onserts are positioned. A pair of spaced apart applicator wheels transfers the onserts from the conveyors onto spaced apart consumer goods traveling past the applicator wheels.

US Classification:

Abstract:

A continuously variable belt drive system including a driving pulley assembly, a driven pulley assembly, and a V-shaped belt engaged to transfer rotary power therebetween is disclosed herein. The driving pulley assembly includes an idler pulley portion. As the belt speed decreases, the belt migrates downward within the driving pulley assembly until it falls within the idler pulley portions, thereby isolating the belt from the rotation of the driving pulley assembly. The driving pulley assembly also includes a belt tensioning mechanism that maintains proper belt tension at all speeds and drive ratios. The tensioning mechanism relies upon a pivotably mounted centrifugal weight arm to provide tensioning as a function of speed. A compression spring provides axial pressure to maintain belt tension over all drive ratios. The spring, acts against a curved cam edge on a pivoting lever arm, which arm transfers an axial force to the rear sheave of the driven pulley assembly.

US Classification:

53415, 531353, 531361, 493420

Abstract:

An in-line insert folder system includes a continuous roll of preprinted inserts, and a cutter for cutting individual inserts from the roll. A transport serially conveys the individual inserts in a downstream direction to a buckle folder that receives the inserts and folds each one along at least one fold line. An applicator serially receives the folded inserts from the buckle folder and applies the inserts to consumer packs such as cigarette packs, for example. The folded inserts may be directly applied to the packs before placement of flexible outer wrap or the folded inserts may be applied onto the flexible outer wrap before that wrap is placed around the packs.

Abstract:

A fan drive system is provided that is hydraulically controlled having an electrical failure mode wherein midrange operation of the fan drive system is maintained. Accordingly, in the failure mode, a fan drive system hydraulic relief valve is not closed thereby ensuring a degree of operation of the fan drive system even during periods of electrical failure.

US Classification:

474 8

Abstract:

The present invention provides a continuously variable belt pulley transfer system that addresses prior deficiencies with CVT-type systems, particularly when used with accessory drive systems. The continuously variable belt drive system includes a driving pulley assembly and a driven pulley assembly, with a continuous belt transferring rotary motion between them. A direct electronic actuation mechanism is used for controlling ratio changes on the pulley transfer assembly. An integrated stepper motion is used as the prime mover for the mechanism. A differential planetary roller screw mechanism converts the rotary motion from the stepper motor to axial motion for actuating the sheave poison of the V-shaped belt.
