Electric bicycle freewheel polytetrafluoroethylene layer spraying device

Abstract

The invention discloses an electric bicycle freewheel polytetrafluoroethylene layer spraying device which comprises a base, wherein a spraying chamber is arranged on the base; a support pillar is arranged on the base; the spraying chamber is arranged on the support pillar; a spraying ball is arranged in the spraying chamber; a plurality of spraying holes are formed in the surface of the spraying ball; a liquid transfer ball is arranged in the spraying ball; a sliding rail which sleeves a sliding block is arranged in the spraying chamber; the sliding block is provided with a hanging pipe; a lifting pipe is arranged in the hanging pipe in a sleeving manner; a hook is arranged at the end part of the lifting pipe; a sprayer is arranged on the base; a liquid spraying pipe is arranged in the support pillar; one end of the liquid spraying pipe is connected with the sprayer and the other end of the liquid spraying pipe is connected with the sprayer through the liquid transfer pipe. The electric bicycle freewheel polytetrafluoroethylene layer spraying device is convenient to spray polytetrafluoroethylene liquid; the sliding block is capable of controlling the hanging pipe to horizontally slide along the sliding rail so that a freewheel can conveniently and horizontally move so as to be uniformly sprayed by thepolytetrafluoroethylene liquid; the polytetrafluoroethylene liquid is recovered by a liquid return hopper; thepolytetrafluoroethylene liquid can be recovered into a liquid storage tank through a liquid return groove.

Description

technical field [0001] The invention relates to a spraying device, in particular to a polytetrafluoroethylene layer spraying device for an electric bicycle flywheel. Background technique [0002] Flywheel: A wheel-shaped accumulator with a large moment of inertia mounted on the rotary shaft of a machine. When the speed of the machine increases, the kinetic energy of the flywheel increases and the energy is stored; when the speed of the machine decreases, the kinetic energy of the flywheel decreases and the energy is released. Flywheels can be used to reduce speed fluctuations during mechanical operation. Working principle: Single-stage flywheel Working principle: when the pedal is stepped forward, the chain drives the flywheel to rotate forward. The axle and rear wheel turn and the bike moves forward. When the pedal is stopped, neither the chain nor the jacket rotates, but the rear wheel still drives the core and the jack to rotate forward under the action of inertia. A...
