Abstract

The utility model discloses a gear driving mechanism having constant lubrication and noise-reduction effects, which comprises a pair of engagement gears having the driving function, wherein the position right ahead the rotary engagement and separation position between the two engagement gears is provided with a blocking member for lubricating oil; a high-voltage oil storage region is formed between the blocking surface of the blocking member and the separation surface between the two engagement gears, and the lubricating oil can be pressed into a tooth slot of each gear again under the action of high voltage. The gear driving mechanism can block the shedding of lubricating grease on the surface of the gears when the engagement gears rotate at high speed, and the purposes of noise reduction and lubricating effect keeping can be attained.

Description

A kind of gear transmission structure with continuous lubrication and noise reduction
Technical field
The utility model belongs to the gear transmission structure technology.
Background technique
In the gear-driven occasion of many application, in order to solve lubricated and to reduce the gear meshing noise, generally the mode of Cai Yonging is to coat the very high lubricant oil of viscosity on gear.But oil body is too high can to influence the part driving torque, and the too low adhesive force of viscosity is not enough, lubricant oil can be got rid of from gear again; Add gear in the engagement driving process, because temperature raises, the lubricant oil that is coated in the gear engagement face also can reduce adhesive force, also can gradually lubricant oil be got rid of, thereby cause lubrication effect to reduce and the increase of gear engagement noise, influences the working life of product.
Summary of the invention
In order to address this problem, the utility model provides a kind of gear transmission structure with continuous lubrication and noise reduction, and the lubricating grease of gear surface comes off in the time of can stopping the engaging gear high speed rotating, reaches the purpose that reduces noise and keep lubrication effect.
The technical solution of the utility model is as follows:
A kind of gear transmission structure with continuous lubrication and noise reduction, comprising the engaging gear that a pair of gearing arranged, be provided with a lubricant oil block piece in the rotation of described two engaging gears engagement position, separation place dead ahead, high pressure oil storage zone of formation between the parting surface of the prevent surface of this block piece and two gears.
Said structure can prevent that lubricant grease from splashing and be got rid of, and reaches the maintenance lubrication effect, reduces the order ground of noise.Its reason is, the zone that surrounds by two gears and block piece, the ravine consistent lubricant throws away at a high speed and produces a zone of high pressure here during the high-speed gear rotation, under the effect of block piece, make the speed vanishing of the lubricant oil that splashes, because the effect of high pressure is pressed into grease unlikely coming off in the backlash of gear again along the direction that rotatablely moves of two gears, thereby continuous lubrication reduces noise, prolong product working life, can be widely used in the mechanism of motorcycle starter and relevant high gear transmission.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the structural drawing of the concrete application of this drive mechanism on the gear-box of motorcycle starter.
Embodiment
Referring to Fig. 1, when the design gear driving mechanism, rotation engagement at gear 1 and gear 2 engagement positions separates locates position, positive forward position, increase an obstacle 3 (shape of the prevent surface of obstacle can be arc, plane or concave surface), just can prevent that lubricant oil 4 from splashing gets rid of, thereby reaches continuous lubrication and reduce the purpose of noise.
Fig. 2 is a kind of concrete structure realized of this driving mechanism on C100 motorcycle motor gear-box, Fig. 2 is the sectional drawing of gear-box, as seen from the figure, a pair of pitch wheel is installed in gear box casing 5---driving wheel 6 and follower 8, the rotation of their phase N directions, the position, dead ahead of their gear engagement separation place is provided with columniform block piece 7, the three surrounds a high pressure oil storage zone A who prevents the spatter loss of lubricant oil jointly, block piece 7 is fixed in the gear box casing 5, or with gear box casing 5 one-body molded acquisitions.

Claims (1)
