摘要:
The ends of a premeasured length of an elastic, thermoset sheave insert material are laminated together in a special splicing jig for fabricating a unitized insert loop, which is subsequently stretched around a sheave into a preformed insert receiving slot along the circumference thereof. The jig holds the ends of the premeasured length of insert material in alignment as a heated mold, included therein, fits snugly around the ends and applies heat to the joint therebetween, into which the insert material, in liquid form, has been inserted to join the ends. The heat thus applied to the joint accelerates the curing of the liquid into the same consistency as the insert; thereby producing a unitized bond between the ends by which the unitized loop is thus formed.

An endless track for traction of a vehicle, such as a construction vehicle, an agricultural vehicle, a forestry vehicle or a military vehicle. The endless track has an enhanced elastomeric material curing capability. In one embodiment, each of a plurality of elastomeric projections of the endless track, such as guide/drive projections or traction projections, comprises elastomeric material defining a cavity to enhance a curing process during manufacturing of the endless track. The cavity may be shaped such that, during the curing process, a heat conductor positioned in the cavity conducts heat from the heat conductor to the elastomeric material of the projection.
摘要:
A splicing device (10) for closing a looped material band (1) comprising two splicing elements (20, 30) intimately linked to the ends (2, 3) of the material band (1), assembled together by fitting two toothings (22, 23) into each other, and locked by a transverse locking rod (15) inserted in the aligned transverse openings (14) of the teeth (13) of each toothing. The splicing elements (20, 30) are made out of a material compatible with that of the material band and comprise a traction core extending longitudinally up to the teeth (13) and surrounding the transverse opening (14) of teeth (13) of each toothing (22, 32) so that, when the splicing device (10) is assembled and locked, the traction cores of the splicing elements ensure the tensile strength of the splicing device (10) while remaining very flexible.

Clockwork movement for a wristwatch, comprising a kinematic chain including at least one belt (20, 21) for transmitting the movements and/or couples between at least two pulleys. The pulleys are held on the bottom plate or the bridges by ball bearings (151, 161, 171, 181). The movement is rewound by means of linear oscillating mass (14) charging four barrels (15, 16, 17, 18) through a couple distributor (40). The barrels are non-parallel to one another. The back cover is covered by inclined glasses (110, 120, 130) allowing the barrels, the linear oscillating mass and at least certain pulleys to be seen. The regulating organ (51) is removable.

The metallic mold 90 includes a product configuration portion 93 formed between an upper mold 91 and a lower mold 92. This product configuration portion 93 is composed so that a rolling element accommodating belt 50 formed by this product configuration portion 93 can include spacer portions interposed between balls adjacent to each other in an infinite circulating passage and also include connecting arm portions for connecting the spacer portions to each other and so that the balls can be aligned in the alignment direction in the infinite circulating passage. The upper mold 91 has a splitting structure. In this splitting structure, a splitting position BL is set at a position passing through a position 91t for forming an end portion on the outer circumferential side in the inner and outer circumferential direction of the infinite circulating passage of the spacer portions 51.

A process for producing a support belt for an elevator system includes steps of: placing at least one cable-shaped tension support in position; embedding the tension support in a first belt layer made from a first plasticizable material to produce a partial belt having a first outer surface and a surface which forms a connecting plane, wherein parts of the tension support project out of the connecting plane and at least parts of the projecting portion of the tension support are covered by the first plasticizable material; and integrally forming a second belt layer made from a second plasticizable material on the connecting surface of the partial belt and the projecting portions of the tension support so as to produce a support belt having the first outer surface on the side of the first belt layer and a second outer surface on the side of the second belt layer.

A flat belt 20 is prepared. A first belt end 21 of the belt 20 has a finger shape and a second belt end 22 of the belt 20 has the complimentary shape to the first belt end 21. An adhesive is applied to one of an end face 21K of the first belt end 21 and an end face 22K of the second belt end 22 or to both. Next, both end faces 21K and 22K are butted. The butted portion B of the first and second belt ends 21 and 22 are pressed in the belt width direction. Due to this, the end faces 21K and 22K are bonded by the adhesive so that the first and second belt ends 21 and 22 become joined.
