Background

The gear structure is widely applied to various machines or products, such as factory machines and watches. In the prior art, a plurality of tooth parts with connecting joints are arranged on a rim of a gear, the tooth parts can be used for meshing with other peripheral gears or related mechanical parts, and the gear can transmit torque and kinetic energy by means of meshing of the teeth.

Since the gear is engaged with a peripheral part or another gear during operation, it is difficult to avoid the phenomenon of abrasion after a period of use. In the past, gears are not easy to find when being worn, and most of the gears are not capable of being replaced or checked until the gears cannot be meshed or slip, so that the machine possibly stops operating suddenly, and temporary mechanical failure causes unexpected and serious loss for a factory.

In view of the above-mentioned drawbacks of the prior art gear structure, the inventor completed the gear structure and manufacturing method with wear indication according to accumulated decades of experience in the industry, and the application and experience acquisition and strength solution of many domestic and foreign patents.

Therefore, when the gear is used for a period of time to generate a wear image, the outer coating layer partially or completely disappears due to wear, so that the original color of the tooth part is presented, and a user can easily detect the wear condition through vision, thereby achieving the purposes of timely replacing and avoiding temporary stop of machines and tools.

In order to achieve the above purpose, the present invention specifically comprises: taking a gear, wherein the material of the gear can be metal, non-ferrous metal alloy, cast iron, powder metallurgy, plastic, steel or plastic steel, or can be finished in a 3D printing mode, and the method is not limited to this. The gear is provided with a plurality of tooth parts on the upper ring, and the outer surface of each tooth part is provided with an outer coating layer, and the color of the outer coating layer is different from that of the tooth part.

Detailed Description

The present invention relates to a gear structure with wear indication and the manufacturing method thereof, and the effect thereof, which will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, the gear with wear display of the present invention mainly includes a gear 1, wherein the gear 1 is provided with a plurality of tooth portions 11; an outer coating layer 2 is provided on the outer surface of each of the teeth 11 in any manner, and the outer coating layer 2 is colored differently from the teeth 11. The gear 1 at least comprises a straight gear, a helical gear, a herringbone helical gear, a bearing gear and a worm, but not limited thereto. The material of the gear 1 may be metal, non-ferrous metal alloy, cast iron, powder metallurgy, plastic, steel material or plastic steel, or finished in a 3D printing manner, and is not limited thereto.

Referring to fig. 2, in one method for manufacturing the outer coating 2 of the present invention, a gear 1 is provided with a mold 3, a recess 31 is preset in the mold 3, and the volume of the recess 31 is slightly larger than that of the gear 1; after the gear 1 is placed in the recess 31, plastic is extruded into the gap between the gear 1 and the recess 31 in an injection molding process (fig. 3), and the outer coating 2 is integrally molded on the outer surface of each tooth portion 11 of the gear 1 by demolding after molding (fig. 4).

Since the surface color of each tooth 11 is different from that of the outer cover 2 in the present invention, for example, the surface color of each tooth 11 is white, and the color of the outer cover 2 is red. Referring to fig. 5, after the gear 1 is used for a period of time, if the whole gear still presents red, it means that the outer coating layer 2 still exists, so as to be used continuously; if the gear 1 is seen by naked eyes to be in a plurality of white colors and the red proportion is relatively reduced, the gear represents that the outer coating layer 2 is mostly worn, so that the gear can be timely reminded of replacement or maintenance in order to avoid the temporary slipping condition or the loss of the meshing effect.

The method of disposing the outer coating 2 can be performed by plating the outer coating 2 on each tooth 11, in addition to the above-described manufacturing method by the two-shot molding method.

The number of the layers of the outer coating layer 2 is at least one, and may be arbitrarily increased to multiple layers, and the colors of the layers are different. For example, the outermost layer is green, the middle layer is yellow, and the inner layer is red, so that the abrasion can be grasped by eyes in real time according to different colors.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
