Chirurgisches Bearbeitungsinstrument, insbesondere Fräser oder Bohrer, der in einem abgewinkelten Schaft (2) eine winkeltolerante Welle (4) führt. Der die Abwinkelung (3) bildende Abschnitt des Schafts (2) wird von einer längs geteilten und leicht zerlegbaren Hülse (22) gebildet. Zweckmäßigerweise steht eine Mehrzahl solcher Hülsen (22) mit unterschiedlicher Abwinkelung zur Verfügung. Die Hülsen werden durch Ringteile (24, 25) zusammengehalten.
摘要:
The invention concerns a protective bellow for drive shaft articulated joint, consisting of a tapered bellow whereof the end with the small diameter (2) is expansible and has a saw-toothed section axially extended by folds (8) so as to enable the effortless radial extension of the bellow for fixing it above the "bowl" of the articulated joint without using equipment of any kind; the central part can advantageously comprise one or several internal helical ribs (5) driving the grease contained in the device towards the articulation when the latter is rotating. Said bellow is designed to be placed around lubricated joints such as universal or constant velocity joints used for transmitting a rotating motion to mobile members, in particular in road motor vehicles and is of particular interest for the industrial sector manufacturing spare parts for repair shops and service centres for cars and heavy vehicles.

[PROBLEMS] Provided are a joint assembly facilitating attachment/detachment of a unit cover for protecting a constant velocity universal joint and improving workability of assembling a total assembly into a vehicle, and a total bearing device assembly for a drive wheel. [MEANS FOR SOLVING THE PROBLEMS] Radially extending plate-like joining surfaces (7b, 7c) are formed by dividing a cylindrical elastomer unit cover (7) into two parts by a plane including the axis. Hook parts (35a, 35b) are formed on the outer edges of the joining surfaces, at positions axially offset from each other. Recesses/projections (34, 36) constructed from projections (34a, 36a), which are formed by expanding the forward ends of the joining surfaces, and from recesses (34b, 36b), which has an annular groove (38a) formed at generally the center of the inner diameter part (38) of the joining surfaces, are formed at generally the center of the joining surfaces (7b, 7c). The recesses/projections (34, 36) are engaged with each other by elastic deformation when the joining surfaces (7b, 7c) abut on each other to detachably fit them to the constant velocity universal joint (3).
摘要:
An object of the present invention is to provide a joint assembly as well as a total assembly of bearing apparatus for a driving wheel having the joint assembly which can improve the detachability of the unit cover for protecting the constant velocity universal joint during transportation and assembly to a vehicle and can improve the workability in assembling the total assembly of bearing to a vehicle. According to the present invention there is provided a joint assembly comprising a secured type constant velocity universal joint, a slide type constant velocity universal joint, and substantially cylindrical unit covers of elastomer in which the secured type constant velocity universal joint includes one outer joint member formed on its inner circumference with a plurality of curved and axially extending track grooves; a joint inner ring formed on its outer circumference with track grooves oppositely to the track grooves; torque transmitting balls contained within ball tracks formed by the track grooves; a cage for rollably holding the torque transmitting balls within the ball tracks; a drive shaft one end of which being connected to the joint inner ring, and a boot mounted on the drive shaft and on an outer circumference at an opened side of said one outer joint member; the slide type constant velocity universal joint including a boot mounted on said drive shaft and on an outer circumference at an opened side of the outer joint member; and the unit covers having reduced diameter portions and being mounted on the outer circumferences of both the constant velocity universal joints characterized in that each of the unit covers is formed as two parts divided along a parting plane including its axis and has radially extending flat abutting surfaces on the parting plane, and that fastening portions formed on the abutting surfaces and adapted to be engaged via a elastic deformation of them so that the unit covers are detachably mounted on both the constant velocity universal joints.
