Abstract
A novel chain saw comprises a motor (1), a coupling (2), a shell (5) and a saw chain (6). The coupling (2) is mounted at the rear end of the shell (5), and the motor (1) is fixedly arranged at the rear end of the coupling (2). A double-enveloping worm wheel (4) and a double-enveloping worm (3) which are meshed with each other are mounted inside the shell (5), and the double-enveloping worm (3) is connected with a spindle of the motor (1) through the coupling (2) and then drives the saw chain (6) to move through a spindle of the double-enveloping worm wheel (4). According to the novel chain saw, a secondary enveloping ring surface worm gear pair is used for replacing original worm and gear pairs such as an Archimedes tooth type worm and gear pair, an involute tooth type worm and gear pair and a ZK tooth type worm and gear pair, the defects in the prior art are overcome, bearing capacity is enhanced, the transmission efficiency of the entire mechanism is improved, and the service life is prolonged.
Description
Technical field
The utility model belongs to stone cutting machine tool technical field, is specifically related to a kind of novel chain saw.
Background technology
Existing stone cutting machine tool adopts archimedes line mostly, involute, the shortcoming such as the worm couple of the profiles of tooth such as ZK slows down, and exists bearing capacity not enough, and volume is larger, and transmission stability poor and service life is short.
The utility model content
The technical problem that the utility model solves: design a kind of novel chain saw, adopt double envelope hourglass worm gearing to substitute original Archimedes, involute, the worm couple of the flute profiles such as ZK, overcome the shortcoming of prior art, increase bearing capacity, improve transmission efficiency and the service life of whole mechanism.
The technical solution adopted in the utility model: a kind of novel chain saw, comprise motor, shaft coupling and housing and saw chain, described shaft coupling is installed in the rear end of housing, and motor is fixed on the rear end of shaft coupling; The two bag worm gears and the two bag worm screws that are meshed are installed in the described housing, and two bag worm screws connect with the main shaft of motor by shaft coupling, and then move by the main shafts drives saw chains of two bag worm gears.
Described two bag worm gears are installed between the housing front/rear end, and two bag worm screws are installed between the end face of the housing left and right sides, and two bag worm screws are positioned at the below of two bag worm gears.
The advantage that the utility model has compared with prior art and effect:
1, the utility model touches an original toe joint, brings up to several toe joints and touches, and makes chain saw in bearing capacity, stationarity, and the aspects such as service efficiency, particularly service life are significantly increased.
2, the utility model two bag worm gears can adopt the ordinary steel manufacturing, greatly reduce the cost of worm gear.
Description of drawings
Fig. 1 is the utility model structural front view,
Fig. 2 is the utility model structure top view.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
A kind of novel chain saw comprises motor 1, shaft coupling 2 and housing 5 and saw chain 6, and described shaft coupling 2 is installed in the rear end of housing 5, and motor 1 is fixed on the rear end of shaft coupling 2.The two bag worm gears 4 and the two bag worm screws 3 that are meshed are installed in the described housing 5, and two bag worm screws 3 connect with the main shaft of motor 1 by shaft coupling 2, and then the main shafts by two bag worm gears 4 drive saw chains 6 and move and cut building stones.Described two bag worm gears 4 are installed between housing 5 front/rear ends, and two bag worm screws 3 are installed between housing 5 left and right sides end faces, and two bag worm screws 3 are positioned at the below of two bag worm gears 4, the further stationarity that improves running.
The utility model adopts the double envelope hourglass worm gearing transferring power and slows down, because the double envelope hourglass worm gearing flank engagement has multiple tooth engagement, and contact-making surface is doublet contact, and the normal velocity of contact wire is large, and synthetic curvature half is through large, contact stress is little, easily go into the advantages such as lubricating oil film, make transmission mechanism at bearing capacity, the motion transmission stationarity, service efficiency, the aspects such as service life are significantly increased.And worm gear can adopt the 35Cr steel making, decrease cost.Compare with Archimedes's Worm Wheel System, in the situation that material and measure-alike, bearing capacity improves 3-4 doubly, transmission efficiency improves 10%, improves 10 times service life, when the same moment of torsion of carrying, can reduce worm gear case volume and weight, be 1/3 of traditional worm gear case.The transmission efficiency of whole mechanism brings up to 88% from 60%, improves service life more than 10 times.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, therefore all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model interest field.
