Therefore, the space of the inner structure of the whole eccentric reciprocating mechanism is reduced, and the weight of the whole mechanism is reduced.
Description
Technical field
The utility model relates to the eccentric reciprocator on a kind of eccentric reciprocator, the especially electric saber saw.
Background technology
At present, the eccentric reciprocator on the electric saber saw generally comprise reduction box, the gear that rotates by motor-driven, the eccentric shaft that is fixedly linked with gear, a pair of support component and drive and the reciprocating lever parts that move back and forth by eccentric shaft.Described support component is generally bearing and described eccentric shaft is fixed.Described gear is arranged on outside the described support component, has so just caused the needed space of reciprocator bigger, and complete machine weight increases and cost increases.In addition, described eccentric reciprocator is typically provided with balance weight and comes the formed momentum of balance reciprocating lever parts.Motion between described balance weight and the lower panel (or guide plate) is sliding friction, and the load of mechanism is bigger like this, can produce a large amount of heat simultaneously.
Summary of the invention
In order to overcome the deficiency of the eccentric reciprocator on the existing electric saber saw, the eccentric reciprocator that provides a kind of internal structure little is provided main purpose of the present utility model.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of eccentric reciprocator of electric saber saw, comprise reduction box, main shaft, the gear shaft, a pair of support component that are fixedly linked by the gear of main shaft drives rotation, with gear and the reciprocating lever parts that move back and forth, wherein, described gear shaft and described motor output shaft are non-parallel setting.In addition, described gear roughly is arranged between the described a pair of support component.
Another purpose of the present utility model is to provide a kind of eccentric reciprocator that can reduce interelement frictional force.
The technical scheme that its technical problem that solves the utility model adopts is: described eccentric reciprocator also comprises guide plate that is fixedly installed in the reduction box and the balance weight that is set on the described eccentric shaft.The direction of motion of described balance weight is opposite with the direction of motion of described reciprocating lever parts, and being arranged on the described guide plate of rolling.Described balance weight is provided with the roller in the described groove of being housed in of plurality of grooves and a plurality of parts, and described roller can roll on described guide plate.
The beneficial effects of the utility model are because of eccentric reciprocator is arranged at described gear between the pair of bearings, to have reduced the space of whole internal structure like this, minimizing complete machine weight; In addition, what balance weight rolled is arranged on the described guide plate, has reduced each other frictional force thereby a large amount of heat of being produced of reducing mechanism phase mutual friction like this, has strengthened mechanism's reliability of operation.

The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of electric saber saw 10 comprises casing 11, is arranged on motor 12 in the casing 11 and the eccentric reciprocator that is driven by motor 12.Described eccentric reciprocator comprises reduction box 1, main shaft 13, is driven and the gear 3 of rotation, the gear shaft 41, a pair of support component 5 that are fixedly linked with gear 3 and the reciprocating lever parts 6 that move back and forth by main shaft 13.Described gear shaft 41 is non-parallel setting with described main shaft 13, and described motor 12 links to each other with main shaft 13.The angular wheel 14 that described main shaft 13 is provided with is meshed with described gear 3.Described gear 3 axially outwards protrudes along it and extends a shaft sleeve part 30, and this shaft sleeve part 30 is set on the described gear shaft 41 regularly.Described support component 5 is a bearing, and one of them support component 5 is set in an end of on the described shaft sleeve part 6, promptly being located at described gear 3, and another support component 5 is arranged on the relative other end of described gear 3 and being set on the described gear shaft 41 of sliding and described gear shaft 41 is fixed on the reduction box 1.Like this, described gear 3 be arranged between the described a pair of support component 5 and help reducing whole electric saber saw 10 internal structure the space and reduce the weight of complete machine.One crank element 4 is provided with gear shaft 41 and the eccentric shaft 43 on main part 40 and the fixing respectively upper and lower surface that is arranged on main part 40.Described reciprocating lever parts 6 are set on the described eccentric shaft 43.
Described eccentric reciprocator also comprises guide plate 7 and the balance weight 9 that is fixedly installed in the reduction box 1.One eccentric block 44 is fixedly installed on an end of the close main part 40 of described gear shaft 41, and described balance weight 9 is set on the described eccentric block 44.
The direction of motion of described balance weight 9 is opposite with the direction of motion of described reciprocating lever parts, thereby comes balance reciprocating lever parts 6 formed momentums, plays the effect that reduces vibration.
Described balance weight 9 is being arranged on the described guide plate 7 of rolling.Described balance weight 9 is provided with the roller 16 in the described groove 15 of being housed in of plurality of grooves 15 and a plurality of parts.Described roller 16 rolls on described guide plate 7.Like this, for rolling friction, rather than sliding friction helps reducing frictional force each other, has reduced the load of mechanism, has reduced a large amount of heat that mechanism's phase mutual friction is produced simultaneously between balance weight piece 9 and the guide plate 7.Thereby, increased mechanism's reliability of operation.
