Abstract

The invention concerns an orientable angular gear-type instrument for easy actuation of a transmission at an angle between 0 and 360 DEG . The instrument comprises two mutually rotating half-housings (1, 1'), rotation being facilitated by a bronze ring (2) the lower part of which is gripped by a ring (3). Sealing is effected by a joint (4). Each half-housing comprises a pinion (5, 6) mounted on ball bearings (7, 8, 9, 10). Linkage of the transmission is effected by a large crown (11) attached to a shaft (12) by a key (13) and a clip (14). Rotation is effected by the shaft (12) mounted on ball bearings (15, 16). The part (17) facilitates remounting of the shaft of the large crown.

Description

ADJUSTABLE CORNER

The present invention relates to an angle gear orientable to three hundred and sixty degrees. In the devices known to date, a universal joint adapted to the transmission allows a limited walking angle. These are difficult to use and lack of ease: indeed during use (cardan shafts can snap during a maneuver.

These devices known to date present for transmission the risk of breakage, hence a danger of accident for the user. The orientable angle gear according to the invention makes it possible to avoid these drawbacks, it is indeed fixed to a material allowing it to be used at a maximum angle without any drawback for the user. It is in fact associated with a material using a transmission whose articulation is very strong. This orientable angle deflection device placed at the articulation of the transmission allows, if the user so desires, an angle of three hundred and sixty degrees. It is set each time that the mechanical transmission of a power cannot be done in a straight line or at a very high angle requiring the use of this type of angle transmission from the receiving member. This allows you to get around the obstacle in interesting and sought after conditions of yield, precision and safety.

The accompanying drawing is a sectional view of this steerable angle gear when the rotation is of two half casing pivoting on themselves. As shown, the device comprises two half-casings 1 and 1 BIS pivoting on themselves, this rotation is facilitated by a bronze ring 2 allowing better sliding and preventing the two half-casings from being in direct contact. A ring 3 fixed to the base of the half box 1 located below the bronze ring allows the assembly to remain united. The shafts 18 and 19 mounted on the bearings 7, 8, 9, 10 these last two watertight. Gables 5 and 6 are fixed at the end of the shafts. The large crown 11 fixed by a key 13 on a shaft 12 thereof mounted on bearings 15 and 16 is intended to serve as an articulation for the transmission during the rotation of the half box 1 on the half box 1 BIS. The device, object of the invention can be used in all cases where the transmission of a tool or a material requires its use so as to ensure an accurate and easy transmission without risk for the user when the device movement is no longer in the axis of the transmission. It can be used on agricultural equipment, in industry, on articulated machines, on the articulated arms of robots requiring transmission, and in any other field whose use of this angle gear is necessary for articulation with an angle. Very important.
