Description

Technical Field

[0001] The utility model relates to the technical field of bevel gear processing, in particular to a double-sided bevel gear processing device. Background Art

[0002] Bevel gears, also known as bevel gears or conical gears, are used to change the direction of a shaft in a mechanical transmission system. Double-sided bevel gears (also known as double-crown gears) are a special type of gear characterized by two conical gear faces and are typically used to transmit rotational motion between two intersecting shafts. Such gears are widely used in automobiles, machine tools, agricultural machinery, and other applications that require a change in the direction of power transmission.

[0003] Chinese Patent Authorization Announcement No. CN220093277U discloses a device for processing arc-shaped bevel gears, comprising a mounting frame, a grinding member, and a positioning member. A first motor is mounted on the upper side of the mounting frame at a position corresponding to the positioning member. A main body of the arc-shaped bevel gear is disposed on the outer side of the positioning member. The grinding member includes a position-adjusting electric push rod. A third hinge is disposed at one end of the position-adjusting electric push rod. An angle-adjusting frame is disposed on the inner side of the third hinge. A first hinge is disposed at the upper end of the angle-adjusting frame. An angle-adjusting electric push rod is disposed on one side of the first hinge. The utility model grinds the arc-shaped bevel gear using a grinding roller. The grinding roller has a special-shaped structure and can adjust the angle and position of the grinding roller. The arc-shaped bevel gear can be grinded in all directions. The grinding operation is performed by engaging the positioning member with the mounting hole of the arc-shaped bevel gear, and the fixing operation is highly convenient.

[0004] In actual use, the existing technology uses a grinding roller to grind the arc bevel gear. Since the ground bevel gear may be exposed to moisture, corrosive gases or chemicals during use, its metal surface will be corroded, causing the surface of the bevel gear to gradually deteriorate, eventually leading to premature damage to the gear and shortening its service life. Based on this, the utility model designs a double-sided bevel gear processing device to solve the above problem. Utility Model Content

[0015] (1) This solution is to put the bevel gear on the positioning plate on the outer surface of the rotating rod, then start the motor to drive the bidirectional screw to rotate, drive the two side plates to move inward at the same time, and the two rotating rods move inward at the same time. The two ends are respectively inserted into the slots through the plug-in blocks to realize the limit connection of the two rotating rods.

The automated device greatly reduces the need for manual operation and reduces the dependence on the operator's skill level, while also reducing labor costs.

[0017] (3) This solution starts the pump and sprays the paint in the barrel through the nozzle and the connecting pipe, and the paint falls on the bevel gear that rotates at a constant speed, so as to quickly complete the spraying process of the bevel gear. By spraying the paint on the surface of the bevel gear, a protective film is provided to prevent the metal surface from being corroded. In addition, some spraying materials can improve the lubrication properties of the gear surface and reduce the friction coefficient, thereby reducing energy loss and improving transmission efficiency. Automatic spraying can avoid the uneven thickness that may occur during manual spraying. In addition, since the bevel gear rotates continuously during the spraying process, it helps to quickly and evenly distribute the paint and accelerate drying. BRIEF DESCRIPTION OF THE DRAWINGS
