Description

A new type of worm gear

Technical Field

The utility model relates to the technical field of worm gears, in particular to a novel worm gear.

Background Art

The worm and worm gear mechanism evolved from the staggered axis helical cylindrical gear mechanism and is a special type of gear mechanism. They are a gear mechanism used to transmit motion between two staggered axes. The worm wheel and worm are equivalent to the gear and rack in their middle plane, and the worm is similar in shape to the screw.

For example, the worm gear disclosed in Chinese patent number: CN2767757Y has a lubricating oil channel inside the friction surface between the worm gear and the worm gear. The lubricating oil channel is directly injected into the friction surface between the worm gear and the worm gear for lubrication. The prominent defects of the worm gear with high friction, high loss and high heat are changed, but the patent does not have the function of angle limiting when in use, so that when the worm gear rotates unexpectedly, the worm gear will also rotate unexpectedly, thereby reducing the stability during use.

The movable connection is provided with a movable ratchet 10. Through the provision of the worm wheel body 1, the worm body 2, the connecting shaft 3, the bearing seat 4, the fixed shaft 7, the vortex spring 8, the movable ratchet 9, the movable ratchet 10 and the adjusting handle 11, the function of facilitating angle limiting is realized, thereby avoiding the accidental rotation of the worm body 2, which causes the accidental rotation of the worm wheel body 1, and improves the stability during use. At the same time, through the provision of the mounting block 5 and the mounting bolt 6, the function of easy installation is realized, which is conducive to installing the entire device to a suitable position, improves the convenience of the overall operation, meets people's use needs, and is worthy of promotion.

Furthermore, the connecting shaft 3 passes through the outer wall of the mounting block 5 through the bearing seat 4, and the connecting shaft 3 is rotatably connected to the mounting block 5 through the bearing seat 4.

Furthermore, through holes are formed at the top and bottom of the mounting block 5 , and a through slot is formed at the center of the mounting block 5 .

Furthermore, the mounting bolt 6 is connected to the mounting block 5 through the through hole, and the bearing seat 4 is connected to the mounting block 5 through the through groove.

Furthermore, the movable ratchet 9 forms a rotating structure with the fixed shaft 7 through the vortex spring 8, and the movable ratchet 9 and the movable ratchet wheel 10 are meshed with each other.

Furthermore, the movable ratchet 9 is rotatably connected to the mounting block 5 via the fixed shaft 7 , and the movable ratchet 9 is symmetrically distributed on both sides of the mounting block 5 .

Furthermore, two movable ratchets 10 are provided, and the two movable ratchets 10 are fixed to the outer wall of the connecting shaft 3, and the tooth blocks on the outer walls of the two movable ratchets 10 are inclined in opposite directions.

Furthermore, an adjustment handle 11 is fixedly connected to one side of the connecting shaft 3 , and the adjustment handle 11 and the connecting shaft 3 are distributed in a “T” shape.

When in use, first, the movable ratchet 9 on one side is turned to rotate, so that the movable ratchet 9 on one side drives the vortex spring 8 to deform and then release the limiting work on the movable ratchet 10 on one side, and then the adjusting handle 11 can be turned to drive the connecting shaft 3 to rotate to one side, so that the connecting shaft 3 drives the worm wheel body 1 to rotate to one side through the worm body 2. When the movable ratchet 9 on the other side is turned, the limiting work on the other movable ratchet 10 will be released through the above principle, so that the worm body 2 can drive the worm wheel body 1 to rotate to the other side, and subsequently, through the elasticity of the vortex spring 8, the movable ratchet 9 will be driven to reset and rotate, so that the movable ratchet 9 will limit the movable ratchet 10 again, thereby realizing the locking function and avoiding accidental rotation.
