Driving Connections, of which the following is a specification.
My invention relates to resilient gear wheels and particularly to gear wheels which are provided with removable resilient connectors between the driving and driven parts thereof.
gear wheel of the above-indicated character which shall be simple and rugged in construction and adapted to be assembled and dismantled with facility.
Another object of my invention is to provide a gear wheel of the above-indicated character, having resilient connectors between the driving and the driven parts, w1th means which shall enable the resilient connectors to be removed for repair with ease and facility.
A further object of my invention is to provide a resilient gear wheel with means for mounting and dismounting the resllient connectors which shall be simple in construc tion and, in no way, interfere with the operation of the gear wheel when the connectors are in position.
More specifically, my invention embodies an improved means for installing or removing the spring connectors of a gear wheel provided with a hub member having radlal projections extending therefrom, a rim member having radial projections and pockets for said connectors formed between said projections. spring connectors embodies a plural1ty of pins which are inserted in holes extending through the spring seats of sald connectors and turn buckles which engage the pins projecting from said spring seats. hus, by operating the turn buckles, the sprlng seats are drawn together and the sprmgs com-- pressed that are contained therebetween, whereby the spring connectors may be removed from, or inserted in, the, pockets formed in the resilient gear wheel.
In gear wheels of the resilient type, which are now in service, the means for removing the spring connectors from between the hub and rim members comprises lugs which pro- One object of my invention is to provide a The means for removing the ect from the spring seats beyond the face of the gear wheel or a special attachment for effectlng the removal of the spring connectors which necessitates the cutting away of a portion of the bearings for the spring seats of the connectors.
In a gear wheel constructed in accordance w1th my nventlon, the means for removing the connectors from the gear wheel ma be completely removed from the gear w eel, when the connectors are in position, and the bearings for the spring seats are in no way altered or weakened.
In the accom anying drawing illustrating my invention, igure 1 is a side elevational View of a portion of a gear wheel constructed Fig. 4 Is an end view of the parts illustrated in Fig. 3.
Referring to the accompanying drawing,
a gear wheel 1 mounted on a shaft 2 em bo ies a hub member 3, having a plurality of radial projections 4, 5 and 6 extending therefrom, and two rim members 7 and 8, wh1ch are provided with radial projections 9 and 10 that register with the radlal projections 4, 5 and 6, extend from the hub member 3. Openings 11 are thus formed through the gear wheel, in each of which are inserted two spring connectors 12. Each of the spring connectors embodies spring seats 13 and 14 having holes 15 and 16 extending therethrough for a purpose to be described later and two helical springs 17 and 18 which are disposed between the two spring seats 13 and 14. The rim members 7 and 8 are provided with a plurality of gear teeth 19 and the hub member is provided with a crank pin 20.
The foregoing description of hub-and rim the pins 21 and 22 which project beyond I the connectors 12. The turn buckles 23 and 24 may then be operated to draw the spring seats 13 and 14 together and compress the springs 17 and 18, in order that ready removal of the connectors 12 from the pocket 11 formed between the radial projections of the hub and rim members may be effected.
In assembling the spring connectors in position in the gear wheel, the s ring seats of two connectors are first aline by means of the pins 21 and 22 and then the springs 17 and 18, disposedbetween the spring seats, are compressed by means of the turn buckles 23 and 24 until the connectors may be freely disposed within the pocket 11 between the hub and rim members. When theconnectors are in proper position between the hub and rim members, the turn buckles 23 and 24 are removed and then the ' pins 22 and 23 withdrawn from the holes 15 and 16 in the spring seats 13 and 14.
Variations in the structure and arrangement and location of parts may be made without departing from the spirit and scope of my invention, and such modifications are intended to be covered by the appended claims.
