Abstract:
A belt installation tool (10) for installing a flexible belt on a pulley. On one side, the radius of the tool (10) is substantially equivalent to the radius of a pulley flange. The bearing surface (12) on this side of the tool stretches the belt and guides the belt onto the pulley. To avoid damaging the belt, the radius of the tool (10) and the pulley flange should be substantially equal over substantial length of the pulley. Centric to this radius, a hole (15) is provided to accommodate a single-end socket that projects through the tool. The socket engages a crankshaft bolt, hence, the belt installation tool (10) is centered on the pulley along the socket centerline. The tool and pulley are then turned with a ratchet attached to the socket. The tool (10) comprises a belt bearing surface (12) having variable radius that allows a belt to be stretched to a proper radius without abrupt radius changes, which could damage a belt. The belt is moved axially from the tool (10) into the pulley grooves by a leaderblock (50), which is provided at the tool radius on the bearing surface (12) adjacent to the pulley grooves. By turning the tool (10) about the crankshaft the leaderblock (50) guides the belt flank, causing it to move into a pulley groove. The leaderblock (50) comprises a lip (52) to further hold the tool (10) on a pulley rim.
Abstract:
A centered/decentered power transmission wheel (10), in which a disc wheel (15), which constitutes the transmission wheel (10), is provided so that it can be moved slidingly along a support member (13), which is mounted on a rotary shaft (11), to maintain by removing or re-mounting a bushing (14), which is normally fitted in the transmission wheel (10), from or on the power transmission wheel (10) the center (C) of rotation of the disc wheel (15) and the axis (0) of the rotary shaft (11) in alignment with each other while the transmission wheel (10) is in a normal operation, and out of alignment while the replacement of a belt or the repairing of a part is carried out, whereby the replacement of a belt, the repairing of a part and other kinds of operations can be carried out speedily without moving the rotary shaft (11) itself.
Abstract:
L'invention concerne un dispositif pour poser et déposer une courroie (C) sur un corps cylindrique (1) de révolution comportant une jante ajourée et une gorge annulaire pour le logement de la courroie posée, ce dispositif étant constitué par un U comportant deux joues (4, 5) permettant de chausser le côté de la gorge de sorte que la joue (4), ou joue de couverture (4) couvre la gorge annulaire temporairement, sur un secteur circonférentiel du corps cylindrique. L'invention concerne également un procédé de pose et un procédé de dépose d'une courroie à l'aide d'un tel dispositif.
Abstract:
A belt installation tool having a substantially planar body (10) having a circumferential surface and a roller (201). The roller (201) radially projects from the body (10). An axis of rotation of the roller (201) is disposed cooperatively with a belt urging member (16). The belt urging member (16) projects from an outer flange (12). The roller (201) urges a belt slightly radially outward from a pulley center. The belt urging member (16) then urges the belt laterally to install the belt in a pulley groove. A second roller (201) projecting radially from the body (10) and having an axis of rotation parallel to the body (10) is used to remove a belt from a pulley.
Abstract:
A tool (17) for installation and removal of power transmission belts (16) from fixed center pulleys (13, 15) in a power transmission system (11). The tool (17) comprises a principal member (18) for attaching to a pulley, thus absorbing forces created during installing and removing belts, and simplifying the process. Separated installing (32) and removing (41) devices are secured to the principal member (18) and are configured to support and maneuver the belt (16) while installing onto, or removing from, the selected pulley (15).
Abstract:
The invention comprises a tool (100) for installing a low modulus type power transmission belt on an engine pulley (p). More particularly on a pulley having two sets of grooves (b, c) whereby two power transmission belts are engaged with the pulley. The tool comprises a substantially semi-circular form having at least two surfaces (21, 31) engaged with a rim (A) and which project radially therefrom. Each of the two surfaces (21, 31) also describe a helical angle with respect to an axis of rotation of the pulley. The first surface (21) urges a belt into a first set of pulley grooves during a first tool rotation. The second surface (31) urges the belt from the first set of pulley grooves to a second adjacent set of pulley grooves during a second rotation of the tool.
