Abstract
Proposed is a high pressure-generating multi-point lubricant injector that enables smooth discharge of a lubricant by uniformly pressurizing a piston with a single power source, and enables active use in multiple injection points, as well as efficient distribution of the lubricant to a drive end and a non-drive end.
Claims5
A high pressure-generating multi-point lubricant injector comprising:
- an upper body in which a motor and a battery for driving the motor are mounted;
- and
- a lower body coupled to the upper body, the lower body comprising
- a storage compartment filled with a lubricant therein,
- a piston provided inside the storage compartment and comprising a nut,
- a screw shaft coupled to the nut and configured to lift and lower the piston while being rotated,
- a driven gear coupled to the screw shaft, and
- a driving gear configured to drive the driven gear by receiving rotational force of the motor,
- wherein the driven gear comprises multiple driven gears arranged symmetrically around the driving gear located at an upper center of the lower body, the screw shaft comprises multiple screw shafts provided at positions corresponding to the driven gears, and the nut comprises multiple nuts coupled to the screw shafts and provided at positions corresponding to the driven gears so that the piston extrudes the lubricant to the outside by uniformly receiving the rotational force of the motor.

A high pressure-generating multi-point lubricant injector comprising:
- an upper body in which a motor and a battery for driving the motor are mounted;
- and
- a lower body coupled to the upper body, the lower body comprising
- a space of a predetermined size,
- a cartridge detachably mounted in the space and filled with a lubricant therein,
- a piston provided inside the cartridge and comprising a nut,
- a screw shaft coupled to the nut, configured to lift and lower the piston while being rotated, and formed through an upper portion of the cartridge,
- a driven gear coupled to the screw shaft, and
- a driving gear configured to drive the driven gear by receiving rotational force of the motor,
- wherein the driven gear comprises multiple driven gears arranged symmetrically around the driving gear located at an upper center of the lower body, the screw shaft comprises multiple screw shafts arranged at positions corresponding to the driven gears, and the cartridge comprises multiple cartridges each including the piston coupled to each of the screw shafts and arranged at positions corresponding to the driven gears so that the lubricant is extruded to the outside from each of the multiple cartridges.
