Abstract
The utility model relates to a reciprocating saw driving device, which comprises a gearbox (17), a sliding bearing (4), a special shaped sliding bearing (9) and a reciprocating lever (5) which is horizontally arranged, wherein, the gearbox (17) is extended out of one end of the reciprocating lever (5); the interior of the gearbox (17) is provided with an output shaft (15) which is parallel to the reciprocating lever (5), one end of the output shaft (15) is fixed with a driven gear (12) which is meshed with a gear shaft (10) of a motor, and the other end of the output shaft (15) is provided with an oscillating lever bearing (16); one end of an oscillating lever (6) is connected with the oscillating lever bearing (16), and the other end of the oscillating lever (6) is connected with the reciprocating lever (5). With the adoption of the structure, circular movement is converted to the axial movement of the oscillating lever (6) by the output shaft (15) via the oscillating lever bearing (16) and the oscillating lever (6), and the reciprocating lever (5) is driven by the oscillating lever (6) to carry out reciprocating movement; when the output shaft (15) is rotated for a circle, the reciprocating lever (5) is pushed by the oscillating lever (6) to make the reciprocating motion for one time. Thereby, the problems of multiple transmission parts, large noise, fast abrasion and short service life of the crank are solved, such as; the utility model has the advantages of simple structure, high efficiency, small noise, long service life, etc.
Description
One, technical field
The invention relates to reciprocating saw, particularly a kind of reciprocating saw power output actuator.
Two, background technology
Its power output actuator of reciprocating saw that uses generally adopts the crank gearing mode to move back and forth at present, parts required during the transmission conversion are more, transmission efficiency is low, and the influence that cooperated by the driving parts precision, loud during reciprocating saw work, quick abrasion between the driving parts causes product short service life.
Three, summary of the invention
Existing reciprocating saw transmission device transmission efficiency is low, work noise big in order to overcome, quick abrasion, service life short disadvantage, the invention provides a kind of and utilizes oscillation bearing to swing to drive reciprocating lever to carry out axially-movable to replace crank-driven reciprocating saw transmission device.The invention solves the technical scheme that its technical problem adopts and comprises the gearbox body that is arranged on the middle cover, sliding bearing and special-shaped sliding bearing are set on the gearbox body, be horizontally set on the reciprocating lever on sliding bearing and the special-shaped sliding bearing, one end of reciprocating lever stretches out gearbox body, be provided with the output shaft parallel in the described gearbox body with reciprocating lever, one end of output shaft is fixed with the driven gear with the engagement of motor gear axle, the other end is provided with Oscillating lever bearing, fork one end is connected with Oscillating lever bearing, and the other end and reciprocating lever flexibly connect.
Be provided with gear shift cover in the described gearbox body, special-shaped sliding bearing is arranged on the gear shift cover, and a side of output shaft is arranged on the gear shift cover by bearing.
After adopting said structure, driving output shaft by motor gear axle engagement driven gear rotates, output shaft is converted to the fork axially-movable by Oscillating lever bearing and fork with circular motion, reciprocating lever waits planar reciprocating under the drive of fork, output shaft rotates a week, fork promotes reciprocating lever and makes a round trip, and has solved that original crank gearing part is many, noise big, quick abrasion, life-span lack problem; Have simple and reasonable, transmission efficiency is high, noise is little, long service life and low cost and other advantages.
