Example Embodiment

[0018] The present invention will be further described below with reference to the drawings and embodiments.

[0019] See figure 1 with figure 2 , A gear quenching mechanism, including a liquid storage barrel 1 and a central shaft drive structure 2. The liquid storage barrel 1 includes a barrel body 11, a barrel lid 12, and a cylinder 13 that drives the barrel lid to rise and fall to open and close. Picture of the cylinder body of the cylinder The barrels are connected together. The piston rod of the cylinder is connected to the barrel cover. An insulation layer 111 is provided on the outer surface of the barrel 11. The liquid storage tank is provided with a hot liquid inlet 14, a hot liquid discharge outlet 15, a cold liquid discharge inlet 16 and a cold liquid discharge outlet 17. Several vertical bearing fixing rods 3 are arranged on the bottom wall of the barrel. The bearing fixing rod has a tubular structure. A support ring 31 is provided at the lower end of the bearin...

Abstract

The invention relates to a gear quenching mechanism. The gear quenching mechanism comprises a barrel body, a barrel cover and a central shaft driving structure for driving a central shaft to rotate. The bottom wall of the barrel body is provided with a plurality of vertically-arranged tubular-structure bearing fixing rods. The bearing fixing rods are provided support rings and liquid inlets. The central shaft rotationally connected to a liquid storage barrel penetrates through the bearing fixing rods. The central shaft is connected with fan blades for driving liquid in the barrel body to flowfrom one ends of the bearing fixing rods to the other ends of the bearing fixing rods when the central shaft rotates. The gear quenching mechanism has the advantages that the heating and cooling effects are good, and bearings do not need to be moved in the heating and cooling switching processes, and the problems of low heating speed, poor surface hardness of shaft holes and liable surface deterioration in an existing gear quenching process are solved.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a gear quenching method of a gear quenching mechanism. Background technique [0002] Gear is a commonly used transmission part in machinery. In order to improve the hardness of the gear, the gear needs to be quenched during the gear machining process. The existing gear quenching process is to first set a plurality of gears to be quenched on a solid bearing fixing rod to form a gear string, then put the gear string in a heating furnace to heat to a set temperature, and then put the gear string to be quenched Transfer from the heating furnace to the cooling furnace for cooling to complete the quenching operation. [0003] The existing gear quenching process has the following disadvantages: since the bearing fixing rod is a solid structure, the heating speed is slow, and the cooling speed of the inner surface of the gear to be quenched (that is, the shaft hole surface and ...
