Definitions
- the invention relates to a role.
- Rollers are known from the prior art, for example, whose rotatably mounted outer casing serves for example for deflecting or guiding a self-contained belt. It is the goal to keep the wear of the belt and reel as low as possible.
- An object of the invention is therefore to provide an improved role, with the simple and thus cost structure of the role especially long service life can be achieved.
- a roll includes the following features: a hollow body whose outer shell forms the rolling surface of the roll,
- the contemplated for abutting faces of mounting and support member are mutually dome-shaped, so that an inclination angle of the axis of rotation of the hollow body relative to the main axis of the fastener is adjustable, - extending through the cavity of the support member through, approximately in the middle of at the other axial end of the carrier element, the carrier element can be fixed with a fixable on the rod fixing means in a selected angle of inclination relative to the fastener element, dome-shaped end side of the fastener fastened to the fastener
- the other end face of the carrier element is likewise dome-shaped and the fixing means or an intermediate element which can be arranged between the fixing means and the carrier element is designed with a matching dome-shaped end face, and the one of the end faces of the carrier element is concave and the other convex.
- the outer surface of the hollow body forming the rolling surface is formed so as to be angularly adjustable with respect to the fastening element, a uniform loading of the belt and roller in the sense of a long service life can be advantageously achieved by a corresponding angular adjustment, wherein the dome-shaped design of the fastening and support element
- a simple and thus comparatively inexpensive to produce Winkelverstelltelltechnik for the role is created. Because a storage between see hollow body and support member must have no or only a very small Winkeleinsteilberry - the actual Winkelein monokeit is indeed realized between support and fastener - can continue to come advantageously with low-cost rolling bearings, such as radial ball bearings.
- the inventive roller may also be considered as Roller outside a belt system and / or used as a support or cam roller.
- the figure shows an exemplary embodiment of the invention, a longitudinal section through a roller.
- the roller comprises a hollow cylinder-like hollow body 10, on the outer shell, for example, a belt is guided, which belongs to a Briefsortier- and / or -Verteilerstrom.
- the roller further comprises a cylinder-like fastening element 21 along the main axis 29 with a hexagonally shaped outer shell, wherein on the lower end side of the fastening element 21 in the axial direction a threaded bore is provided, via which the fastening element 21 is firmly connected to its installation environment.
- the fastening element 21 is formed dome-like inwardly cambered. Approximately in the middle of the dome-shaped end face is fastened with the fastening element 21 in the direction of the main axis 29 extending, at least at its longitudinal ends formed with a thread Boi zen 22.
- the bolt 22 is firmly screwed into the fastening element 21 and additionally secured by suitable measures against loosening, for example by a cohesive bonding.
- the bolt 22 and the fastening element 21 can also be connected to one another in a different way, but in principle may also be formed integrally with one another and with the same material.
- the bolt 22 is enclosed by a hollow-cylinder-like carrier element 24, which is formed at the lower axial end with a flange-like projection and the lower end side bulged according to the dome-shaped end side of the fastening element 21 to dome-shaped axially outward is.
- the carrier element 24 is formed with a dome-shaped end side, which is inserted axially inward, so that after an intermediate washer 26 has been fitted to the carrier element 24 with a matching calotte-shaped outwardly bulging end face, the carrier element 24 can be f ⁇ xierbar by means of a screwed onto the upper thread of the bolt nut 22 27 with a predetermined inclination of a rotation axis 19 of the roller relative to the main axis 29 of the fastener 21 f ⁇ xierbar.
- the intermediate plate 26 is available for example as a standard standard component.
- the two dome-shaped regions are formed such that their radii have a common, lying on the main axis 29 of the fastener 21 midpoint.
- the axial length of the bolt 22 and support member 24 and the diameter of the bolt 22 and the inner diameter of the support member 24 are chosen such that the axis of rotation 19 of the hollow body 10 by an inclination angle ⁇ in a range of about +/- 3 ° relative to the Main axis 29 of the fastener 21 is angularly adjustable.
- the hollow body 10 of the roller is connected via two radial ball bearings 31 and 32 with the carrier element 24.
- the outer shells of the two outer rings of the ball bearings 31 and 32 abut the inner shell of the hollow body 10.
- the upper end face of the outer ring of the upper ball bearing 31 and the lower end face of the outer ring of the lower ball bearing 32 are axially secured in the hollow body 10, each with a snapped into a corresponding groove on the inner surface of the hollow body 10 circlip.
- the inner shells of the inner rings of the two ball bearings 31 and 32 bear against the outer casing of the carrier element 24.
- the inner ring of the lower ball bearing 32 rests with its lower end face on the paragraph formed by the support member 24 and the upper end side of the inner ring of the upper ball bearing 31 is axially secured with a locking ring which is inserted into a correspondingly formed on the outer surface of the support member 24 groove ,
- the both inner rings axially reinforced resonatedes spring element 35 is arranged, whereby a backlash-free training of storage is achieved with advantage.
- the ball bearings 31 and 32 comprise in known manner between their outer and inner rings arranged sealing washers for sealing a space containing the balls, wherein the balls are arranged guided in a cage.
- the roller In the upper region of the hollow body 10 is further closed by a lid 15, wherein the lid 15 is in turn formed with a likewise closable opening through which the nut 27 is accessible.
- the roller can be made corrosion-resistant, for example by using stainless steel materials.
- ball bearings In other embodiments, of course, other types of rolling bearings can be used as ball bearings, it is for example also possible to form the nut and the washer in one piece, attach the bearings differently and / or at least form part of the storage in one piece with other elements.
