As depicted in figs. 1 and 2, a kind of motor and gear drive 100, comprise the first coupling 110, second coupling 120 and the elastic component 130 between first, second coupling 110,120.
Offer axis hole in the middle of described first coupling 110, and first coupling 110 one end is plane; The other end is provided with convex axle 111 and with convex axle 111 homonymy and 4 projections 113 of spaced radial certain distance, and spaced between protruding 113.
Offer perforate in the middle of described second coupling 120, and second coupling 120 one end is provided with the shaft shoulder 121, the other end is provided with 4 spaced dogs 123.
Refer to Fig. 3, in the middle of described elastic component 130, offer axis hole, and outside elastic component 130, be provided with formation 8 spaces between 8 spaced elastic bumps, 133,8 described elastic bumps 133.
First coupling 110 is connected by described elastic member 130 with the second coupling 120.Hold 4 projections 113 of the first coupling 110 and 4 dogs 123 of the second coupling 120 in 8 spaces of described elastic member 130 respectively, and often hold a projection 113 and a dog 123 respectively in adjacent two spaces.
In above-mentioned motor and gear drive 100, the first coupling 110 is connected by described elastic member 130 elasticity with the second coupling 120, can absorb vibration, reduce noise.
Be appreciated that described protruding 113 or the quantity of dog 123 be not limited to 4, can also be 3,5 or 6 etc., can arrange according to specific needs.Described protruding 113 can be identical with the number of dog 123, also can be different, but the quantity of described elastic bumps 133 is the total sum of protruding 113 and dog 123, like this, protruding 113 can be contained in the space that elastic bumps 133 formed with dog 123, and preferably, the quantity of projection 113 or dog 123 is equal, at this moment, often a projection 113 and a dog 123 is held respectively in adjacent two spaces.
In one embodiment, protruding 111 are evenly arranged along the first coupling 110 circumferencial direction, and dog 123 is evenly arranged along the second coupling 120 circumferencial direction, and elastic bumps 133 is evenly arranged along elastic component 130 circumferencial direction.Such structure can make assembling more quick and easy.
In one embodiment, described elastic bumps 133 is cylindric, described elastic bumps 133 is not limited to cylindric, and can also be the rule such as prism, ball or irregular shape, the elastic bumps of these shapes also can play the effect compensating radial deflection or angular deflection.
Further, described elastic component 130 is made up of quality of rubber materials, and its elastic effect is good, and easy to process, easy-formation, cost of production is low.In other embodiments, elastic component 130 can be other elastic materials, as long as can be out of shape, produces a restoring force, can compensate radial deflection and angular deflection.
In one embodiment, described motor and gear drive 100, also comprise motor 140 and gear 150.Described motor 140 is as power source, produces driving torque; Described gear 150 changes speed and the direction of motion.Concrete, described gear 150 can be bevel gear, but is not limited to bevel gear.Described motor 140 is provided with rotatingshaft 142; Stomidium 152 is offered in described bevel gear one end.Described rotatingshaft 142 passes the axis hole of the first coupling 110 and elastic component 130 successively, and stretches into the stomidium of bevel gear, so that the first coupling 110 is connected to motor 140.Described bevel gear coordinates with the perforate of described second coupling 120, bevel gear to be connected to the second coupling 120.Thus by the cooperation of the first coupling 110 and the second coupling 120, motor 140 and bevel gear are coupled together again.
Owing to making or the problem of assembling, above-mentioned motor 140, gear 150 and and the parts such as gear 150 meshed gears between can there is certain angular deflection or radial deflection.Refer to Fig. 4 and Fig. 5, due to the setting of elastic component 130, when there is this skew, elastic component 130 deformable, thus adapt to this skew, make the first coupling 110 and/or the second coupling 120 produce angular deflection or radial deflection, and then the skew between each parts such as motor 140, gear 150 is compensated.
Referring again to Fig. 1 and Fig. 2, in one embodiment, described motor and gear drive 100 also comprise a bearing 160, gear 150 is brachy pyramid gear, bearing 160 is set on gear 150, and one end of bearing 160 is against the shaft shoulder 121 of the second coupling 120, the other end is near the gear teeth of gear 150, and this bearing 160 pairs of gears 150 carry out single-bearing support.If an axle only has a strong point, when rotating, axle can produce circuit oscillation, and the longer oscillating quantity of axle is larger.Therefore, this structure adopts brachy pyramid gear, and oscillating quantity is less, and carry out flexibility near flexible 130, one end of the second coupling 120 fixing, plays certain protection when transmitting torsion to gear 150.
The utility model also provides a kind of electric circular saw, and it comprises described motor and gear drive 100.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make multiple distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
