11 results about "Crown gear" patented technology

A crown gear (or a contrate gear) is a gear which has teeth that project at right angles to the face of the wheel. In particular, a crown gear is a type of bevel gear where the pitch cone angle is 90 degrees. A pitch cone of any other angle is simply called a bevel gear. Crown gears normally mesh with other bevel gears, or sometimes spur gears, a typical use being a crown gear and pinion system which allows a rotary motion to be shifted 90 degrees.

A knife die assembly having a fine adjustment mechanism and laser ranging

ActiveCN118322268BLaser rangingGear wheel
This invention discloses a die-cutting assembly in the field of die-cutting technology, specifically a die-cutting assembly with a fine-tuning mechanism and laser ranging. It includes a base plate, a lower left support and a lower right support fixedly mounted on the base plate, a lower die-cutting assembly mounted between the lower left and lower right support seats, an upper left support fixedly mounted on the upper end of the lower left support seat, an upper right support fixedly mounted on the upper end of the lower right support seat, and an upper die-cutting assembly positioned between the upper left and upper right support seats. Two guide rods are symmetrically fixedly connected at the upper end of the upper die-cutting assembly between the upper left and upper right support seats. The beneficial effect of this invention is that when the position of the upper die-cutting assembly needs to be finely adjusted left or right, the locking mechanism is first released from locking the rotating crown gear. At this time, rotating the knob drives the worm gear to rotate, causing the two threaded sleeves on the bidirectional transmission screw to move closer or further apart. The micro-component enables the transmission mechanism to move left and right.

A wall pre-buried wire pipe dredging and threading device for a concealed project

ActiveCN224555095UGear wheelGas passing
This utility model discloses a device for clearing and threading wires through pre-embedded conduits in concealed engineering projects, relating to the field of building construction technology. The utility model includes a threading rod with an air passage inside. One end of the threading rod is fitted with a threading head, and a crown gear is rotatably mounted on one end of the threading head. A conical head is fixedly mounted on the outside of the crown gear, and multiple annularly distributed scrapers are fixedly mounted on the outer surface of the conical head. A drive assembly is installed inside the threading head, including fan blades rotatably mounted inside the threading head. A drive gear is fixedly mounted on the top of the fan blade's shaft, and an air inlet is provided on the threading head. In this utility model, compressed gas blows the fan blades through the air inlet, causing them to rotate. The fan blades drive the drive gear to rotate, which in turn drives the crown gear to rotate. The crown gear drives the conical head to rotate, and the conical head drives the scrapers to rotate. Combined with manual operation, the threading rod can be manually inserted and withdrawn within the conduit to clear obstacles and facilitate the passage of the threading rod.

A device for removing impurities from absorbent cotton

This utility model relates to the field of medical product manufacturing technology. It includes a base plate with a support plate fixedly connected to its outer wall. An adsorption mechanism, comprising a motor, is provided on the outer wall of the support plate. By incorporating this adsorption mechanism, the motor drives the connecting shaft to rotate, simultaneously rotating the pulley and the crown gear. The crown gear meshes with a gear, and the crown gear, in turn, drives the positioning rod to rotate, causing multiple magnetic blocks to rotate within the processing box. During the rotation of the crown gear, a second gear is driven to rotate, simultaneously rotating the brush cylinder within the processing box. This achieves the goal of adsorbing impurities through the magnetic blocks while the brush cylinder combs the degreased cotton, preventing impurities from becoming entangled in the degreased cotton during use and preventing the cotton from clumping, which could lead to incomplete removal of impurities and increased safety hazards during use.
