Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
In a reduction gear transmission including an input shaft, a satellite carrier driven by a pinion on said input shaft, a satellite gear rotatably mounted in said carrier, an output shaft on which said carrier is journaled, a drive gear drivably mounted on said output shaft, a holding gear journaled on said output shaft, and means for establishing a driving relation between said holding gear and said output shaft, the improvement consisting of: a. a satellite gear comprising two sections of different radii with one section having a greater number of teeth than the other b. the satellite gear section with the smaller number of teeth continuously meshing with the drive gear and that with the larger number of teeth continuously meshing with the holding gear.
Claim 2
Dependent Claim
126 words
In a reduction gear transmission including an input shaft, a satellite carrier driven by a pinion on said input shaft, a satellite gear rotatably mounted in said carrier, an output shaft on which said carrier is journaled, a drive gear drivably mounted on said output shaft, a holding gear journaled on said output shaft, and means for establishing a driving relation between said holding gear and said output shaft, the improvement consisting of: a. a satellite gear comprising two sections of different radii with one section having a greater number of teeth than the other b. the satellite gear section with the smaller number of teeth continuously meshing with the drive gear and that with the larger number of teeth continuously meshing with the holding gear.
Claim 3
Dependent Claim
126 words
In a reduction gear transmission including an input shaft, a satellite carrier driven by a pinion on said input shaft, a satellite gear rotatably mounted in said carrier, an output shaft on which said carrier is journaled, a drive gear drivably mounted on said output shaft, a holding gear journaled on said output shaft, said satellite gear continuously meshing with said drive and holding gears to establish a driving relation between said holding gear and said output shaft, the improvement consisting of: a. an infinite gear ratio assembly including two elements, b. means for drivably connecting one of said elements to the output shaft, c. means for connecting the other of said elements to the holding gear, and d. a variable driving connection between said elements.
Claim 4
Dependent Claim
126 words
In a reduction gear transmission including an input shaft, a satellite carrier driven by a pinion on said input shaft, a satellite gear rotatably mounted in said carrier, an output shaft on which said carrier is journaled, a drive gear drivably mounted on said output shaft, a holding gear journaled on said output shaft, said satellite gear continuously meshing with said drive and holding gears to establish a driving relation between said holding gear and said output shaft, the improvement consisting of: a. an infinite gear ratio assembly including two elements, b. means for drivably connecting one of said elements to the output shaft, c. means for connecting the other of said elements to the holding gear, and d. a variable driving connection between said elements.
Claim 5
Dependent Claim
112 words
The reduction gear transmission of claim 2 in which: a. one of said elements comprises an inner pair of confronting bevel gears keyed to the output shaft, b. the other of said elements comprises an outer pair of confronting bevel gears disposed about said inner pair, c. all of said bevel gears having bevelled faces which define a space, and d. the variable driving connection consists of a ring in said space, bevel gear face engaging members carried by said ring, and means to shift said ring in a plane normal to the axis of said bevel gear to move some of said face engaging members radially outwardly and others radially inwardly.
Claim 6
Dependent Claim
42 words
The reduction gear transmission of claim 3 in which the bevelled faces of the bevel gears have radial grooves, the ring is formed with a series of longitudinal passages, and the face engaging members take the form of pins in said passages.
Claim 7
Dependent Claim
25 words
The reduction gear transmission of claim 4 in which the grooves are of V-cross section and the pins have carried tips received in the grooves.
Claim 8
Dependent Claim
22 words
The reduction gear transmission of claim 3 in which the outer pair of bevel gears are mechanically interlocked to rotate in unison.
Claim 9
Dependent Claim
64 words
The reduction gear transmission of claim 3 in which the ring is carried by a plate, together with: a. a pivotal mounting for said plate, b. a sleeve having a threaded bore and connected to said plate opposite to the pivoted mounting by a loose connection. c. a screw stem in said threaded bore, and d. an operating member for rotating said screw stem.
