Embodiment Construction
[0013] Referring to the accompanying drawings, a guide wheel of the present invention is welded with copper at the bottom of the track of the guide wheel close to the axis, and is characterized in that: between the welding copper and the contact surface at the bottom of the wheel track, there is a horizontal The cross-section is a trapezoidal copper inlaid with a narrow top and a wide bottom, and its center line coincides with the center line of the bottom of the wheelway. seam joint.
[0014] Further, the guide wheel can be made of cast iron.
[0015] Further, the soldering copper and the trapezoidal inlaid copper are tin brass.
[0016] Further, the angle of the pointed protrusion is not less than 50 degrees.
[0017] Preferred embodiments of this invention are described herein, including the best mode known to the inventors for carrying out the invention. Variations of the preferred embodiments may become apparent to those of ordinary skill in the art upon reading the fo...

The invention discloses a guide wheel. Copper is welded at a position where a wheel way of the guide wheel is close to the bottom of the axis, trapezoidal embedded copper with a cross section narrow at the top and wide at the bottom is embedded at the bottom of the wheel way between the welded copper and a contact area at the bottom of the wheel way, the central line of the trapezoidal embedded copper is coincident with that of the bottom of the wheel way, the lower wide edge of the trapezoidal embedded copper forms a shape-angled protrusion along the central line, and the trapezoidal copper bar and the bottom of the wheel way as well as the welded copper are both in seamless combination. The guide wheel can be made of cast iron, the welded copper and the trapezoidal embedded copper are tin brass, and the angle of the sharp-angled protrusion is not smaller than 50 degrees. The guide wheel is simple in structure, only local abrasion can be caused to the welded copper in the wheel way of the guide wheel, and large-area or full shedding is avoided, so that service cycle of the guide wheel can be effectively prolonged.
Description
technical field [0001] The invention relates to the field of mechanical structures, in particular to a guide wheel. Background technique [0002] In the prior art, steel wire ropes are usually used in some large-scale lifting equipment, and the guide wheel is a part that changes the direction of movement of the wire rope. As the friction increases, the wire rope and the guide wheel will be damaged faster. In order to minimize the wear on the wire rope, tin brass is usually welded at the bottom of the guide wheel track. The reason is that the mechanical properties and process properties of tin brass are similar to those of H90 ordinary brass. Copper, and has high corrosion resistance and anti-friction properties, so tin brass can be used as a wear-resistant alloy. At the same time, because of its excellent cold working performance, hot bending and hot extrusion performance, medium machinability, and easy welding. [0003] However, with long-term use, the soldered tin brass w...
