Abstract
The invention discloses a main transmission mechanism of a metal printing machine. The main transmission mechanism comprises a central shaft, wherein an input gear is sleeved at one end of the central shaft; an output transmission gear is sleeved at the other end of the central shaft; and a harmonic transmission device is arranged between the input gear and the output transmission gear and sleeved on the middle part of the central shaft. The main transmission mechanism has the advantages of simple structure, small volume, low noise, long service life, reduced production cost and improved working efficiency.
Description
Technical field:
The present invention relates to a kind of main drive gear of tin graphed sheet machine.
Background technology:
At present, be provided with more big speed ratio gear train in the main drive gear of tin graphed sheet machine, make the entire equipment complex structure, volume is big, and noise is big during work, the fault height, and the maintenance cost height has directly influenced operating efficiency, the production cost height.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of simple in structure, volume is little, noise is little, the main drive gear of long service life, minimizing production cost, the tin graphed sheet machine of increasing work efficiency.
Purpose of the present invention is achieved through the following technical solutions: a kind of main drive gear of tin graphed sheet machine, main drive gear comprises central shaft, be with the input gear on one end of central shaft, be with output drive gear on the other end of central shaft, be provided with harmonic drive between input gear and the output drive gear, harmonic drive is enclosed within on the middle part of central shaft.
Further improvement of the present invention is: harmonic drive comprises wave producer, flexible gear and rigid gear, wave producer is an annulus, wave producer is enclosed within on the central shaft, be with the flexible gear that has external toothing on the outer circumference surface of wave producer, be with the rigid gear that has ring gear on the outer circumference surface of flexible gear.
Further improvement of the present invention is: the external tooth size of flexible gear and the internal tooth size of rigid gear depend on the size of wave producer profile.
The advantage that the present invention compared with prior art has: in main drive gear, add harmonic drive, replaced traditional big speed ratio gear train, entire equipment is simple in structure, volume is little, noise is little, long service life, has also reduced production cost simultaneously, has improved operating efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of A-A among Fig. 1;
Number in the figure: 1-central shaft, 2-input gear, 3-output drive gear, 4-wave producer, 5-flexible gear, 6-rigid gear.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of embodiment of the main drive gear of tin graphed sheet machine of the present invention as Fig. 1, main drive gear comprises central shaft 1, be with input gear 2 on one end of central shaft 1, be with output drive gear 3 on the other end of central shaft 1, be provided with harmonic drive between input gear 2 and the output drive gear 3, harmonic drive is enclosed within on the middle part of central shaft 1.Harmonic drive comprises wave producer 4, flexible gear 5 and rigid gear 6, wave producer is an annulus, wave producer 4 is enclosed within on the central shaft 1, be with the flexible gear 5 that has external toothing on the outer circumference surface of wave producer 4, be with the rigid gear 6 that has ring gear on the outer circumference surface of flexible gear 5.Harmonic drive is simple in structure, and volume is little, and is in light weight, and harmonic drive has the following advantages: gear range is big; Nie He the number of teeth is many simultaneously: the number of teeth that harmonic drive meshes simultaneously can reach 30%, even more some more.And in the ordinary gear transmission, Nie He the number of teeth has only 2-7% simultaneously, and just because of many these the unique advantages of while total number of teeth in engagement, so harmonic drive is higher compared with common mechanical deceleration device precision, the bearing capacity of tooth is bigger, and then realizes large speed ratio, small size; Bearing capacity is big: well-known, total number of teeth in engagement is many simultaneously for Harmonic Gears, and promptly the number of teeth of bearing load is many, under the material situation identical with speed ratio, is subjected to loading capability will substantially exceed other transmission.The power bracket of its transmission can be from several watts to tens kilowatts; The kinematic accuracy height: because multiple tooth engagement, generally speaking, harmonic gear is compared with the ordinary gear of same precision, and its kinematic accuracy can improve four times; Motion does not steadily have and impacts, and noise is little: gear teeth engaging-in, to nibble out be distortion along with flexible gear 5, progresses into and withdraw from gradually rigid gear 6 between cog, flank of tooth contact in the engagement process, sliding velocity is little, and does not have suddenly and change; Backlash can be adjusted: harmonic drive is in engagement, the external tooth size of flexible gear 5 and the internal tooth size of rigid gear 6 depend on the size of wave producer 4 profiles, and two tooth-formation of gear sizes, therefore can make the return difference of transmission very little, some situation even can be zero side clearance; The transmission efficiency height: compare with other transmission of identical speed ratio, harmonic drive is because moving component quantity is few, and the speed of mesh tooth face is very low, therefore efficient is very high, under different speed ratio situations (in the 60-250 scope), efficient is about about 96%-65%, and the wearing and tearing of the flank of tooth are very little; Alignment is good: the high speed shaft of harmonic drive, slow-speed shaft are positioned on the same axis; Can realize to confined space transmission campaign and power: adopt sealed soft gear harmonic drive, can drive and be operated in high vacuum, be corrosive and the mechanism in other hazardous medium space, this distinct advantages of harmonic drive is that other transmission mechanism is inaccessible; Can realize high speedup motion: because the efficient height and the mechanism itself of harmonic drive, therefore little, the lightweight advantage of volume is desirable high speeder in addition.
Be provided with harmonic drive among the present invention, in harmonic drive, tooth is that face contacts with the engagement of tooth, add that total number of teeth in engagement (overlap coefficient) is many simultaneously, thereby unit are load is little, bearing capacity is higher, the gearratio of single-stage Harmonic Gears, can reach i=70～500, the volume of entire equipment is little, in light weight, and transmission efficiency height, life-span are long, stable drive, nothing are impacted, noiselessness, the kinematic accuracy height has also reduced production cost simultaneously, has improved operating efficiency.
