目前，在大多数齿轮中频淬火热处理生产行业中，齿轮的中频感应单齿淬火大多采用的是直接连续式加热淬火方式。这种淬火方式，由于感应器开始进入时，电流、电压滞后，设备输出功率都未达到最大值，功率损耗较大，难免在齿轮的齿根处及齿轮两端面处出现淬火软带，出现了淬火软带齿轮的使用寿命就会大大的降低，在使用中齿轮出现早期疲劳断裂。 At present, in most gear intermediate frequency quenching heat treatment production industries, the intermediate frequency induction single tooth quenching of gears mostly adopts the direct continuous heating and quenching method. In this quenching method, since the current and voltage lag when the sensor starts to enter, the output power of the equipment does not reach the maximum value, and the power loss is large. The service life of the hardened soft belt gear will be greatly reduced, and the gear will experience early fatigue fracture during use.

为解决上述技术问题，本实用新型采取的技术方案是：提供一种齿轮中频淬火屏蔽装置，其特征在于：包括上屏蔽板、下屏蔽板；所述上屏蔽板和下屏蔽板均为长方形，长方形一侧设置一凸台，且凸台中部设置有仿齿形凹槽；所述上屏蔽板两侧通过螺钉与上屏蔽板加强筋固定连接；所述下屏蔽板两侧通过螺钉与下屏蔽板加强筋固定连接；所述上屏蔽板加强筋与下屏蔽板加强筋之间设置有上下屏蔽板连接筋。 In order to solve the above technical problems, the technical solution adopted by the utility model is to provide a gear intermediate frequency quenching shielding device, which is characterized in that it includes an upper shielding plate and a lower shielding plate; both the upper shielding plate and the lower shielding plate are rectangular, One side of the rectangle is provided with a boss, and the middle part of the boss is provided with an imitation tooth-shaped groove; the two sides of the upper shielding plate are fixedly connected with the reinforcing ribs of the upper shielding plate through screws; the two sides of the lower shielding plate are connected with the lower shielding plate through screws. The reinforcing ribs of the plates are fixedly connected; the upper and lower shielding plate connecting ribs are arranged between the reinforcing ribs of the upper shielding plate and the reinforcing ribs of the lower shielding plate.
所述上下屏蔽板连接筋与上屏蔽板及下屏蔽板设置有不大于2mm的间隙。所述下屏蔽板的厚度比上屏蔽板的厚度至少厚5mm。所述上屏蔽板的厚度为10mm。所述上屏蔽板、下屏蔽板均为紫铜板。 The connecting ribs of the upper and lower shielding plates are provided with a gap not greater than 2 mm with the upper shielding plate and the lower shielding plate. The thickness of the lower shielding plate is at least 5mm thicker than that of the upper shielding plate. The thickness of the upper shielding plate is 10mm.

本实用新型提供的齿轮中频淬火屏蔽装置的上屏蔽板、下屏蔽板均设置有仿齿形凹槽，且下屏蔽板比上屏蔽板厚，这种结构保证了当感应器全部进入齿廓时，达到满功率，使齿轮中频淬火过程中齿根及齿端面不存在淬火软带，进而增强齿根及齿端面的抗疲劳强度，延长齿轮的使用寿命。 Both the upper shielding plate and the lower shielding plate of the gear intermediate frequency quenching shielding device provided by the utility model are provided with imitation tooth-shaped grooves, and the lower shielding plate is thicker than the upper shielding plate. This structure ensures that when the inductors all enter the tooth profile , to achieve full power, so that there is no quenching soft zone in the tooth root and tooth end surface during the intermediate frequency quenching process of the gear, thereby enhancing the fatigue resistance of the tooth root and tooth end surface, and prolonging the service life of the gear.
