Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electroplating devices, and further relates to the field of roller or drum type electroplating devices, and specifically relates to a rubber-coated wheel for electroplating gantry rollers. Background Art
[0002] The rubber-coated wheel is a rubber-coated roller or drum-type device, which is mainly used in equipment parts with buffering functions, increased friction, reduced vibration, etc. The main application scenario of the rubber-coated wheel described in the utility model is the roller of the electroplating gantry.
[0003] The main matching structure of the rubber-coated roller wheel currently used is to open one or more annular fixing grooves in the circumferential direction of the roller hub, and to open annular grooves corresponding to the number of the hub grooves and matching each other in the circumferential direction of the rubber wheel. The concave and convex grooves of the hub and the rubber wheel are matched with each other to fix the wheel. Some even need to add a certain amount of adhesive in the groove to increase the tightness of the rubber wheel and the hub. With this matching method, the hub and the rubber wheel can achieve a complete locking effect in the axial direction by matching the grooves. In the circumferential direction, there are many types of materials used in the hub part and the rubber wheel part, and not all materials have the characteristics of acid and alkali resistance and high temperature resistance. If used for a long time in an environment with strong acidity and alkali or large changes in temperature and humidity, there will be corrosion of the hub part or slight deformation of the rubber wheel part or thermal expansion and contraction, resulting in loosening of the rubber wheel and the hub, so that the hub and the rubber wheel will slide relative to each other in the circumferential direction during the use of the rubber-coated wheel, affecting the use. As a result, some rubber-coated wheels need to add a certain amount of adhesive in the groove to increase the tightness between the rubber wheel and the hub in the circumferential direction, which is more troublesome.
[0004] The shortcomings of existing rubber-coated wheels: Since the rubber-coated wheels are made of cast iron, the wheel hub is corroded during long-term use in the above scenario, causing it to become loose and unable to be fixed to the rubber wheel in the circumferential direction, so that it cannot be used and can only be replaced.
[0005] In view of this, the present utility model is proposed. Summary of the invention
[0006] The technical problem to be solved by the utility model is to solve the problem that the existing wheel hub and rubber wheel become loose in the circumferential direction and slide relative to each other when used for a long time in an environment with strong acidity and alkalinity or with large temperature and humidity changes, thus affecting the use.
[0007] The inventive concept of the utility model is: by designing a matching structure, without increasing the difficulty of parts processing, in the above application scenarios, through the matching of mechanical structures, the problem of the hub and the rubber wheel being loose in the circumferential direction and unable to be fixed due to various reasons during long-term use can be effectively solved.

DETAILED DESCRIPTION
[0033] like Figure 1-4 As shown, the rubber-coated wheel for electroplating gantry roller is specifically implemented as follows:
[0034] The wheel hub 1 is a stainless steel wheel hub with high strength and corrosion resistance, and is the main load-bearing structure of the rubber-coated wheel.
[0035] The rubber wheel 2 is made of a plastic material with certain strength and elasticity, and its main functions are to reduce vibration, increase cushioning, and increase friction.
[0036] There are two wheel hub spindle mounting threaded holes 8, which are distributed on the left and right parts of the wheel hub spindle.
[0037] There are two concave rings 4 and two convex rings 5 in the outer annular groove of the hub, which are evenly and staggeredly arranged along the radial direction of the hub main axis.
[0038] There are six convex teeth 6 and six concave teeth 7 on the outer gear ring of the hub, which are evenly and staggeredly arranged along the circumference of the outer gear ring of the hub.
[0039] There are two concave rings 14 and two convex rings 15 in the inner annular groove of the rubber wheel, respectively, which are evenly and staggeredly arranged along the radial direction of the hollow inner wall of the rubber wheel body 11 .
[0040] The number of the convex teeth 12 and the concave teeth 13 of the inner gear ring of the rubber wheel are six respectively, and they are evenly and staggeredly arranged along the circumference of the inner gear ring body of the rubber wheel.
[0041] The wheel hub 1 is used as the main assembly body, and the rubber wheel 2 is used as the accessory. The inner annular groove concave ring 14 of the rubber wheel and the inner annular groove convex ring 15 of the rubber wheel are matched with the outer annular groove concave ring 4 of the wheel hub and the outer annular groove convex ring 5 of the wheel hub. The inner gear ring convex teeth 12 of the rubber wheel and the inner gear ring concave teeth 13 of the rubber wheel are matched with the outer gear ring convex teeth 6 of the wheel hub and the outer gear ring concave teeth 7 of the wheel hub. The rubber wheel is put on the wheel hub. The rubber-coated wheel assembled in this way has uniform and good fixing force in the axial and circumferential directions, which effectively reduces the frequency of manual replacement of the rubber wheel and greatly improves the service life of the rubber-coated wheel.
[0042] Working principle: The wheel hub and the rubber wheel are fixed in the axial direction by matching the concave ring 14 in the inner annular groove of the rubber wheel and the convex ring 15 in the inner annular groove of the rubber wheel with the concave ring 4 in the outer annular groove of the wheel hub and the convex ring 5 in the outer annular groove of the wheel hub. After the convex teeth 12 in the inner gear ring of the rubber wheel and the concave teeth 13 in the inner gear ring of the rubber wheel and the convex teeth 6 and concave teeth 7 in the outer gear ring of the wheel hub are matched and connected, the wheel hub and the rubber wheel are fixed in the circumferential direction. After the improvement of the mechanical structure mentioned above, the rubber-coated wheel has a very good fixing force in both the axial and circumferential directions, which can largely solve the loosening problem caused by the harsh application environment and has better practicality in the actual application process. The actual effects before and after the improvement are as follows: Figure 4 shown.
[0043] Finally, it should be noted that the above embodiments are only examples for clear explanation. The present utility model includes but is not limited to the above embodiments. It is not necessary and impossible to list all implementation methods here. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. All implementation methods that meet the requirements of the present utility model belong to the protection scope of the present utility model.
