Abstract
Abstract A device for centering the spider trunnions in the eyes of the corresponding fork arms during the assembling of universal joints, said device comprising a pair of oppositely disposed holding members which extend from the outside into each of the annular spaces defined by the circumferential wall of the eye and the outer surface of the spider trunnions inserted therein and thereby center and hold a pair of spider trunnions in centered position within the eyes; and a process for assembling universal joints which comprises the steps of inserting the four spider trunnions into the respective fork eyes, centering a pair of oppositely disposed trunnions in the corresponding eyes with the aid of said centering device, clamping the other pair of trunnions in place, removing the centering device and mounting the roller bearings in the spaced between the eyes and the trunnions centered therein, removing the clamps from the other trunnion pair and mounting the roller bearings in the spaces between the eyes and the said other trunnions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
53 words
A device for centering the spider trunnions in the corresponding eyes of the fork members of a universal joint, said device comprising a pair of holding members which extend from the outside into the space between the walls of the eyes and the spider trunnions to center the spider trunnions in the eyes.
Claim 2
Independent Claim
53 words
A device for centering the spider trunnions in the corresponding eyes of the fork members of a universal joint, said device comprising a pair of holding members which extend from the outside into the space between the walls of the eyes and the spider trunnions to center the spider trunnions in the eyes.
Claim 3
Dependent Claim
51 words
A centering device according to claim 1, which is constructed in the form of pliers and comprises two holding members which are longitudinally slidably guided for movement toward each other, each of which centers and supports one of two oppositely disposed spider trunnions in the eye of the associated fork member.
Claim 4
Dependent Claim
27 words
A centering device according to claim 2, wherein a pair of stops is arranged at a fixed distance from the common axis of the two holding members.
Claim 5
Dependent Claim
165 words
In a process of assembling a universal joint, in which the four spider trunnions are journaled with the aid of anti-friction bearings in the eyes of the corresponding fork members, the steps of a. inserting the four spider trunnions into the eyes of the corresponding fork members and centering a first pair of trunnions in the eyes associated therewith by applying a centering device thereto, b. clamping the second pair of spider trunnions in place with a clamping device and removing the centering device from the first pair of trunnions, c. inserting and anti-friction bearing into each annular space between each of said first pair of trunnions and the wall of the eye associated therewith, and fixing said bearings in place, d. removing the clamping device from the second pair of spider trunnions, and e. inserting and anti-friction bearing into each annular space between each of said second pair of trunnions and the wall of the eye associated therewith, and fixing said bearings in place.
Claim 6
Dependent Claim
165 words
In a process of assembling a universal joint, in which the four spider trunnions are journaled with the aid of anti-friction bearings in the eyes of the corresponding fork members, the steps of a. inserting the four spider trunnions into the eyes of the corresponding fork members and centering a first pair of trunnions in the eyes associated therewith by applying a centering device thereto, b. clamping the second pair of spider trunnions in place with a clamping device and removing the centering device from the first pair of trunnions, c. inserting and anti-friction bearing into each annular space between each of said first pair of trunnions and the wall of the eye associated therewith, and fixing said bearings in place, d. removing the clamping device from the second pair of spider trunnions, and e. inserting and anti-friction bearing into each annular space between each of said second pair of trunnions and the wall of the eye associated therewith, and fixing said bearings in place.
Claim 7
Dependent Claim
374 words
In a process of assembling a universal joint according to claim 4, the steps of a. inserting a first pair of oppositely extending spider trunnions into the eyes of the corresponding first fork members and centering said first pair of trunnions in the eyes associated therewith by applying a centering pliers thereto, b. inserting the first fork members, together with the spider and the centering pliers, into a first clamping device and seating the free ends of the second pair of oppositely extending spider trunnions in a pair of recesses arranged at right angles to the common axis of a first pair of bearing insertion rams, whereby the first pair of spider trunnions held by said centering pliers are brought into true angular alignment with the common axis of said first pair of bearing insertion rams, c. clamping the first fork members and the second pair of spider trunnions in place with said first clamping device and removing the centering pliers from the first pair of spider trunnions, d. inserting an anti-friction bearing into each annular space between each of said first spider trunnions and the wall of the eye associated therewith, fixing said bearings in place and removing said first clamping device, e. inserting the second pair of oppositely extending spider trunnions into the eyes of the corresponding second fork members and centering said second pair of trunnions in the eyes associated therewith by applying said centering device thereto, f. inserting the first and second fork members, together with the spider and the centering pliers, into a second clamping device and seating the spreading stops of said centering pliers in recesses arranged on a common axis parallel to the common axis of a second pair of bearing insertion rams, whereby the second pair of spider trunnions held by said centering pliers are brought into true angular alignment with the common axis of said second pair of bearing insertion rams, g. clamping the second fork members in place with said second clamping device and removing said centering pliers, and h. inserting an anti-friction bearing into each annular spAce between each of said second spider trunnions and the wall of the eye associated therewith, fixing said bearings in place and removing said second clamping device.
