Description
Technical field
The new shape of this practicality relates to a kind of power saws cutter, especially the power transmission shaft on the power saws cutter.
Background technology
At present, the power saws cutter of selling on the market, its structure is by housing, be installed in the cutter on the housing, the power transmission shaft that is connected with cutter and the drive unit of power transmission shaft are formed, wherein, drive unit is that a motor and bent axle thereof constitute, and power transmission shaft is made up of power transmission shaft front portion and power transmission shaft rear portion, cutter is fixed on the power transmission shaft front portion, the power transmission shaft rear portion is provided with the slideway that slides for the drive motors bent axle, and slideway generally is a breach, and crankshaft end places on the described breach, slide at the drive lower edge of motor breach, thereby the promotion power transmission shaft is realized the reciprocating action to cutter, plays the effect of sawing.But there is following defective in the transmission shaft structure in the above-mentioned power saws cutter: 1), since power transmission shaft mostly be plastics and make, during the work of power saws cutter, bent axle slides and produces friction along the slideway surface, make the slideway surface produce heat, especially the slideway periphery is heated obviously, easy deformation influences bent axle and slides, even whole power transmission shaft is scrapped because of distortion; 2), because power transmission shaft sliding way periphery is the place of stressed maximum, and, make its texture deliquescing along with friction generates heat, undercapacity also is the cause that causes the slideway distortion, thereby the service life of infringement power transmission shaft.
Practical new shape content
The purpose of the new shape of this practicality is to overcome above-mentioned the deficiencies in the prior art, and a kind of good heat dissipation effect is provided, is subjected to force intensity power saws cutter drive shaft big and simple in structure.
For achieving the above object, the technical scheme of the new shape of this practicality is: a kind of power saws cutter drive shaft, comprise the power transmission shaft rear portion that the power transmission shaft that is connected with cutter is anterior and connect with the bent axle of drive motors, the power transmission shaft rear portion is provided with the slideway that the bent axle for drive motors slides, and the slideway periphery at power transmission shaft rear portion is provided with fin.The power transmission shaft rear portion is provided with groove, and fin and groove shapes are suitable, and are fixed in the groove.Groove is located at the periphery of slideway, and suitable with the slideway shape.And fin be anchor, cementation or be linked in the groove, slideway is n shape.And fin is a sheet metal, and thickness is 0.5mm to 3mm.
The beneficial effect of the new shape of this practicality is, owing to be fixed with metal fin at the slideway periphery, this fin not only can improve the compressive strength of slideway, and it is good with its thermal conductivity, the heat that the slideway periphery is produced is got rid of fully, overcome the prior art middle slideway because of producing the defective of heat easy deformation, guarantee electronic according to the cutter working stability; Have again, this fin can by anchor, fit or cement in slideway periphery and get final product, it is simple in structure.
Description of drawings:
Fig. 1 is the new shape power transmission shaft schematic diagram of this practicality.
Fig. 2 is the rearview of Fig. 1.
Fig. 3 is the A-A profile of Fig. 2.
Fig. 4 is that the new shape driveshaft applications of this practicality is in the schematic diagram of power saws cutter.
Among the figure: 1 is that power transmission shaft, 2 is that cutter, 3 is that power transmission shaft front portion, 4 is that power transmission shaft rear portion, 5 is that drive motors, 6 is that drive motors bent axle, 7 is that slideway, 8 is that fin, 9 is that flange, 10 housings, 11 are groove.
The specific embodiment
As shown in Figure 1 to Figure 3: a kind of power saws cutter drive shaft 1, comprise power transmission shaft anterior 3 that is connected with cutter 2 and the power transmission shaft rear portion 4 that connects with drive motors bent axle 6, power transmission shaft rear portion 4 is provided with the slideway 7 that slides for drive motors bent axle 6, slideway 7 peripheries at power transmission shaft rear portion 4 are provided with groove 11, and groove 11 shapes and slideway 7 are suitable.Fin 8 is suitable with groove 11 shapes, and is fixed in the groove 11.Fin 8 is to adopt the big and good sheet metal of thermal diffusivity of intensity, and makes its thickness between 0.5mm to 3mm.Slideway 7 is n shape, and is provided with flange 9 at side, and the part of groove 11 is to form via the flange 9 of slideway 7, and the bent axle 6 and the contact area of slideway 7 are increased.And fin 8 is to make and the groove shape adapting, and be close to the periphery that flange 9 is installed to slideway 7, the fin 8 and the contact-making surface of slideway 7 are increased, the heat that is produced when drive motors bent axle 6 slides in slideway so just can pass on the fin 8 soon and be dispersed into rapidly in the air, makes slideway 7 keep stable.And the sheet metal fixed form can be anchor, fit or cement in the groove 11.And the new shape of this practicality adopts is to anchor, as shown in Figure 1.
Operation principle: as shown in Figure 4, the power transmission shaft 1 of the new shape of this practicality is applied on the power saws cutter, and the power saws cutter of this structure is similar to power saws cutter of the prior art, and difference is to have installed fin 8 additional on slideway 7 peripheries of its power transmission shaft 1.The power saws cutter comprises housing 10, be installed in the cutter 2 on the housing 10, the power transmission shaft 1 that is connected with cutter 2 and the drive unit of power transmission shaft 1 are formed, wherein, drive unit is that a drive motors 5 and drive motors bent axle 6 thereof constitute, and power transmission shaft 1 is made up of power transmission shaft anterior 3 and power transmission shaft rear portion 4, cutter 2 is fixed on power transmission shaft front portion 3, power transmission shaft rear portion 4 is provided with the slideway 7 that slides for drive motors bent axle 6, slideway 7 is n v notch vs, drive motors bent axle 6 ends place on the described n v notch v, slide along breach in drive motors bent axle 6 ends under the drive of drive motors 5, thereby promote power transmission shaft 1, realize reciprocating action, play the effect of sawing cutter.At described n v notch v is that slideway 7 back sides install n shape metal fin 7 additional, not only can strengthen the slideway compressive strength, and make good heat dissipation effect and simple in structure.
