This reducer can be used in various installation forms when considering the oil level.<\/p>\n\n\n\n<h3>Body<\/h3>\n\n\n\n<p>The reducer body is made by high-strength gray cast iron. Processed by high-precision numerical control equipment, it has high matching accuracy. It avoids the overload of the gear, and its high precision also ensures the uniform load state of the bearing and the lowest noise.<\/p>\n\n\n\n<h3>Gear Parts<\/h3>\n\n\n\n<p>The gears are processed by heat treatment and gear grinding. The high-precision gears ensure the side clearance of the gears and make the load-bearing capacity of the tooth flank side reasonable and uniform; The worm in worm gear transmission is also treated by heat treatment and fine grinded, and the worm gear material is made of high strength wear-resistant bronze KK alloy.<\/p>\n\n\n\n<h3>Lubrication<\/h3>\n\n\n\n<p>Gear parts in the reducer are lubricated by oil immersion or forced lubrication. The lubricating oil is mineral oil or synthetic oil (or special oil) to ensure that gear parts will not malfunction due to poor lubrication. Generally, the increase of lubricating oil number will have an impact on the performance of the reducer. Unfavorable factors: \u2460 Increase in oil temperature, \u2461 Decrease in efficiency; Favorable factors: \u2460 Reduced noise, \u2461 Strong sealing performance, \u2462 Increased load-bearing capacity of worm gears or gears.<\/p>\n\n\n\n<h3>Seal<\/h3>\n\n\n\n<p>The oil seal at the output shaft prevents lubricating oil from leaking, and also prevents external dust from entering the reducer. When it is used in high ambient temperatures (heating furnaces, smelting production lines, etc.), the oil seal should be made of high-temperature resistant fluororubber materials.<\/p>\n\n\n\n<h3>Bearing<\/h3>\n\n\n\n<p>The bearings used in the reducer are all wear-resistant bearings. Under the action of gears, it is oil-immersion lubrication or forced circulation lubrication. If the above two lubrication methods still cannot be used, the bearing shall be coated with sufficient grease and sealed.<\/p>\n\n\n\n<div style=\"height:3px\" aria-hidden=\"true\" id=\"ab\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3>Cooling<\/h3>\n\n\n\n<p>The reducer generally does not require any additional cooling. The surface of the general body is sufficient to enusure the heat generated by the reducer when the reducer is running under the condition of natural air convection. [Except for<\/p>\n\n\n\n<h3>Paint<\/h3>\n\n\n\n<p>The surface paint of the reducer shall be supplied according to the default color (blue) and type when the user has no special requirements.<\/p>\n\n\n\n<h2>CONDITIONS OF USE<\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" id=\"ac\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul><li>Ambient temperature-40\u2103~50\u2103 (when starting below 0\u2103,the lubricating oil needs to be heated to above 0\u2103 or add lubricating oil antifreeze).<\/li><li>The altitude shall not exceed 1000m.<\/li><li>There is no corrosive liquid, harmful gas, vapor, radiation, etc. in the working environment.<\/li><li>The input speed of the reducer is not more than 1800r\/min.<\/li><li>The circumferential speed of the gear is not more than 22m\/s.<\/li><li>Suitable for various work systems, allowing forward and reverse operation.

If it is damaged, Please replace a new seal.<\/li><li>Add lubricating oil <\/li><li>Fill the reducer with clean lubricating oil. For the type of lubricating oil, please refer to the lubricating oil selection table, and add the oil level to the required position (see 5.1.1.1)\u3002<\/li><li>Note! When replacing the lubricating oil, it is never allowed to mix different types or brands of lubricating oils together, otherwise it will reduce the lubrication effect or lose the lubrication effect of the rotating parts.<\/li><li>Screw on the breather plug (cup).<\/li><\/ul>\n\n\n\n<h3>Grease lubrication<\/h3>\n\n\n\n<p>Grease lubrication of double-sealed bearings<\/p>\n\n\n\n<p>When the double-sealed bearing leaves the factory, the bearing manufacturer injects proper amount of grease into the bearing, so it is not necessary to lubricate the reducer in the process of daily maintenance, but only need to replace it during overhaul.<\/p>\n\n\n\n<p>Other types of grease lubrication , except for the double seal bearing, the reducer manufactured by our company adopts the structure of straight through pressure oil filling cup, and the extreme pressure lithium base grease No.3 is used in this part when it leaves the factory.When lubricating this part, as shown in Figure 25, use a grease gun to inject the lubrication point through the oil cup.<\/p>\n\n\n\n<p>Note! When changing grease, do not mix greases with different soap bases.<\/p>\n\n\n\n<h3>Replacement of oil seal<\/h3>\n\n\n\n<div class=\"wp-container-27 wp-block-columns\">\n<div class=\"wp-container-25 wp-block-column\">\n<p>As shown in Figure 26, use a tool to remove the oil seal from the reducer. Note! In the process of removing the oil seal, the tool should not be inserted too far or too deep to avoid damage to the shaft diameter, bearing and body.<\/p>\n\n\n\n<p>Apply grease evenly to the oil seal on the body or flange and the inner and outer edges of the oil seal.<\/p>\n\n\n\n<p>As shown in Figure 27, use the assembly fixture to install the oil seal into the body.<\/p>\n\n\n\n<p>Note! In the process of assembling the oil seal, if there is a sharp structure such as a keyway on the output shaft, please separate it with soft plastic<\/p>\n<\/div>\n\n\n\n<div class=\"wp-container-26 wp-block-column\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"818\" height=\"261\" src=\"http:\/\/www.evergear-service.com.cn\/wp-content\/uploads\/2022\/09\/25-1.jpg\" alt=\"\" class=\"wp-image-512\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3>Clean the breather plug (cup)<\/h3>\n\n\n\n<ul><li>When the breather plug (cup) has accumulated a layer of dust, it should be cleaned, at least once every six months.
