A bicycle chain guiding device that substantially encloses a front chain wheel inside an interior cavity at least partially defined by a first and a second wall, the second wall provided with entry and exit openings to allow the chain to enter and exit the interior cavity. The entry and exit openings may further be provided with tapered end to allow for entry and exit of the chain at multiple angles.

A power compass saw with a housing that accommodates a lifting rod for the up and down movement of a longitudinal saw blade attached thereto, has a toothed side and a saw blade back and with a guide roller which supports the saw blade back and has a central groove into which the saw blade extends with its saw blade back and is guided therein, the central circumferential groove has tapered groove sides with a 5° taper, the saw blade back has a straight portion and an end beveled portion with beveled edges having a 7° taper at both sides, the saw blade back has diametrically opposed edges provided at a transition from the straight portion to the beveled portion, and the saw blade back has a width which is measured between the diametrically opposed edges and is greater than a width of a bottom of the circumferential groove.

A device for the reduction of axial movement of the main shaft gears (2) in a transmission containing at least two countershafts. The main shaft gears (2) are held axially by two washer discs (3, 4) which is designed to be a pressing device (5, 6) on the main shaft (1) for at least one of the main shaft gears (2) against the washer disc (3) holding the main shaft gear (2) axially.

The present invention relates to a forage harvester blower including a blower rotor having a plurality of generally radially extending rotor paddles which operate in a corresponding substantially cylindrical housing, characterised in that said housing is provided with adjustment mechanism for at least locally adjusting the diameter of the housing. The present invention further relates to a method for optimising the operation of a forage harvester blower and to a method for preventing damage to a forage harvester blower during operation.

An oscillating grinder (10) with a housing (12) a grinding sheet holder (14) having clamping means (20, 23; 200, 230; 334) for receiving a grinding sheet (16), whose grinding sheet ends (17, 19) can be clamped firmly to the grinding sheet holder (14), and in which the clamping means (20, 23; 200, 230; 334, 1334) are levers with a pivot axis (24; 224; 40; 440; 1440) supported on the grinding sheet holder side and clamping jaws (22; 220; 1222; 336, 338) that clamp the grinding sheet (16) on one end, preferably manually actuatable on the other end, can be equipped faster, more conveniently and more securely with a grinding sheet (16) by providing that one of the grinding sheet ends (19) for one-handed operation can be clamped solely by insertion between first clamping means (20, 23; 200, 230; 334; 1334), and the other grinding sheet end (17), likewise for one-handed operation, can be clamped after being placed in second clamping means (34; 334; 1334) and after their actuation; the grinding sheet (16) can be tensed tautly by its subsequent motion, together with the clamped grinding sheet end (17), in particular pivoting, away from the first clamping means (20, 23; 200, 230; 334; 1334).

A telescopic shaft is provided. The telescopic shaft includes a first shaft including a first coupler having an inner circumferential surface including an external straight groove and an external inclination groove formed thereon, the external straight groove having a semi-circular cross section and being formed in parallel to a rotation axis and the external inclination groove having a semi-circular cross section, being inclined with respect to the external straight groove at a predetermined angle, and being shaped like a spiral, a second shaft including a second coupler inserted into the first coupler and having an outer circumferential surface including an internal straight groove and an internal inclination groove formed thereon, the internal straight groove having a semi-circular cross section and corresponding to the external straight groove and the internal inclination groove having a semi-circular cross section, being inclined in an opposite direction to the external inclination groove at a predetermined angle with respect to the internal straight groove, and being shaped like a spiral, and a plurality of balls arranged in a line in an axial direction between the external straight groove and the internal straight groove, one ball being arranged between the external inclination groove and the internal inclination groove, wherein the first shaft and the second shaft are coupled to extend and retract in an axial direction, thereby preventing play from occurring in a circumferential direction and preventing separation of balls.

A method for producing an adjustment fitting, particularly for a vehicle seat is provided, whereby an outer wheel is associated with a first fitting part, the wheel having inner toothing, and having an inner wheel that can be associated with a second fitting part, the wheel having outer toothing, wherein the inner wheel having the outer toothing is inserted into the outer wheel having the inner toothing eccentrically to a rotational axis in the manner of a wobble mechanism, wherein partial eccentric elements are inserted rotatably with respect to each other in an eccentric receiving chamber formed between the rotational axis and the inner wheel so as to produce variable eccentricity, wherein a transmission element having an engagement element for actuating the partial eccentric element is inserted such that the engagement elements interacts with a catch of the partial eccentric element. In spite of the production tolerances of the components, overall higher quality and higher operational safety of the produced adjustment fitting are to be achieved. For this purpose, the geometry of the partial eccentric element is measured, and the geometry of the transmission element is individually adapted according to the data of the measurement before inserting the transmission element.
