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.

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 bearing fixing rod. A plurality of liquid inlet holes 32 penetrating the inner and outer circumferential surfaces of the bearing fixing rod are provided in the area above the supporting ring of the bearing fixing rod. The liquid inlet hole is an inclined hole with the inner end bottom and the outer end high. A counterbore 112 is provided on the bottom wall of the barrel. The bottom wall of the counterbore is provided with a blind hole 113 and a channel 114 connecting the inner space of the barrel and the bearing fixing rod. The upper end of the blind hole is provided with a chamfer. A shaft hole 121 is provided on the lid. The shaft hole is a through hole. The lid and the barrel are sealed and connected together. The liquid storage barrel forms a sealed space when the lid is on the barrel body. The liquid storage barrel is provided with a vent 115. The exhaust hole is provided with a one-way valve 116 that opens to the outside of the liquid storage tank. The lower end of the bearing fixing rod is penetrated and supported in the counterbore. A central shaft 4 rotatably connected to the liquid storage tank is penetrated in the bearing fixing rod. The central shaft is connected with a fan blade 41 that drives the liquid in the barrel from one end of the bearing fixing rod to flow into the other end when the central shaft rotates. The lower end of the central shaft is sealed and rotatably connected in the blind hole. The upper end of the central shaft is sealed and rotatably connected in the shaft hole. The central shaft drive structure is used to drive the central shaft to rotate. The central shaft driving structure 2 includes a motor 21 fixed on the lid, a first gear 22 connected to the central shaft and located on the upper surface of the lid, and a second gear 23 connected to the power output shaft of the motor for driving the first gear .
[0020] The gear quenching method of the gear quenching mechanism of the present invention is as follows: in the first step, a plurality of gears 5 to be quenched are sleeved on the bearing fixing rod, and then an upper pressure sleeve 6 is sleeved and pressed on the gear to be quenched at the top. The support ring is supported under the lowest gear to be quenched; the second step is to shrink the cylinder to make the barrel cover cover on the barrel; the third step is to deliver the heating fluid to the liquid storage barrel to heat the gear to be quenched to the need When the heating fluid is in contact with the outer surface of the gear to be quenched and heated, it also enters the bearing fixing rod through the liquid inlet to reach the gear to be quenched and contacts and heats with the inner surface of the gear to be quenched. The heating also passes through the bearing fixing rod. The central axis of the fan rotates to drive the fan blades to rotate, and the fan blades drive the heating fluid to flow in the bearing fixed rod to improve the heating efficiency of the gear to be quenched; the fourth step is to discharge the heating fluid in the liquid storage tank; the fifth step is to remove the cooling fluid The gear to be quenched is transported to the storage tank to cool down to the required temperature. The coolant is in contact with the outer surface of the gear to be quenched and cooled, and also enters the bearing fixing rod through the liquid inlet to reach the gear to be quenched and the same as the inner surface of the gear to be quenched. Surface contact cooling. During cooling, the fan blades are driven to rotate through the rotation of the central shaft located in the bearing fixing rod. The fan blades drive the coolant to flow in the bearing fixing rod to improve the cooling efficiency of the quenched gear; the sixth step, discharge the storage barrel The coolant inside; the seventh step, take out the gear on the gear fixing rod.
[0021] The liquid inlet hole on the bearing fixing rod is inclined with the inner end low and the outer end high. During heating (the third step) and cooling (the fifth step), the direction of rotation of the center rod is to drive the blades to drive the bearing fixed rod The fluid inside flows upward. During the heating and cooling process, the lid sealing cover is arranged on the barrel body to form a sealed space for storage, and the entire storage barrel is filled when the heating liquid is heated.
[0022] When the heating liquid is discharged in the third step and the cooling liquid is discharged in the sixth step, the central shaft driving structure starts the rotation of the central shaft, so that the liquid in the fan driving bearing fixed rod flows from bottom to top.
