Abstract
The inventive toothed laminated steel belt gearing is made up of a transmission belt and drive and driven wheels. The transmission belt is a piece of laminated steel belt with sprocket holes and the laminated steel belt made up of strip steel is close to the outer cylindrical surfaces of the drive and driven wheels and intermeshes with the gear teeth of the two wheels, to prevent them from sliding each other. The manufacture method includes the following steps: winding several rings on the cylindrical mould; then welding the two ends on the steel belt by the laser or electron beam welding and at last punching the sprocket holes with a forming punch.
Description
Technical field
The invention belongs to the mechanical transmission in the mechanical engineering field.Be particularly related to a kind of tape driving device and manufacture method thereof
Background technique
When the driving shaft and the driven shaft apart from each other of machine, and when requiring strict velocity ratio, main at present bush roller chain wheel drive mechanism or the toothed chain driving mechanism of adopting, the shortcoming of these two kinds of mechanisms is velocity ratio changes in wave shape, and, complex structure, cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of velocity ratio and remain unchanged, and simple in structure, the band tooth Composite Steel tape handler that cost is very low.This device is specially adapted to Bicycles and Motorcycles, and its cost is than low 10 times approximately of conventional device, about 10 times of economical with materials.
The band tooth multilayer steel belt driving device that arrives involved in the present invention, comprise driving belt, driving wheel and follower, driving belt is a multilayer steel band 1 that has perforation, multilayer steel band 1 is close to driving wheel 2 external cylindrical surfaces and follower 3 external cylindrical surfaces, and with the gear teeth meshing of two-wheeled, to prevent mutual slip, form a kind of band tooth flat belt driving device thus, that finishes the between centers strictness decides to compare transmission.
The tooth pitch of multilayer steel band does not influence the constant of velocity ratio, therefore can become 10 times increase tooth pitch, greatly simplifies the structure; Be limited on the tooth pitch length less than driving wheel bag arc length degree.The constraint conditio of tooth pitch is that the outer circumference of driving wheel and follower should equal integer after divided by tooth pitch.
The width of driving wheel and follower external cylindrical surface should be equal to or greater than the width of steel band.
The raw material of multilayer steel band around some circles, adopts laser or electron beam welding for the band steel then on formwork for cylindrical columns, two is welded on the steel band, keeps each layer of steel band, use forming punch then in vertically closely contact, go out perforation, prevent that each layer steel band from laterally sliding, make band tooth multilayer steel band thus.
The advantage of this band tooth multilayer steel belt driving device has: with one be about 1 meter driving belt relatively, thousand of the nearly row of the part number of bush roller chain or toothed chain, and the present invention's part only; This steel band is built up by the multilayer steel band, during transmission and the top circle cylinder be close to, and with the gear teeth meshing of two-wheeled, therefore, its velocity ratio remains unchanged; During this Steel Belt Transmission, do not have the various frictions between part, the cost of this steel band is very low, and the life-span is very long.
Description of drawings
Fig. 1 is band tooth multilayer steel belt driving device figure.
Fig. 2 is a Composite Steel band edge sectional view.
Fig. 3 is the side cross-sectional views of Fig. 2.
Fig. 4, Fig. 5, Fig. 6 are the belt wheel figure that puts by drawing convention.
Among the figure: 1. multilayer steel band, 2. driving wheel, 3. follower.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, band tooth multilayer Steel Belt Transmission is similar to the flat belt transmission, and velocity ratio is a constant, and absorbing is good, but transmission capacity is much bigger.Owing on steel band and belt wheel, done the perforation and the gear teeth, therefore realized the power transmission with the gear teeth and frictional force.Because tooth pitch do not influence velocity ratio, so tooth pitch can do very greatly, and is generally big about 10 times than bush roller chain approximately.The upper limit of tooth pitch is limited by steamboat bag arc length degree mainly, and general tooth pitch only is smaller than bag arc length degree, keeps steamboat to have a tooth engagement at least.Constraint conditio is that the girth of steamboat and bull wheel must be the integral multiple of tooth pitch when tooth pitch designs.
Multilayer steel band 1 is made raw material by commercially available band steel, when being used for bicycle or motorcycle transmission, the width that steel band is general is 10～12mm, thickness of strips is 0.15～0.2mm, make a cylinder according to the steel band girth, when steel band just around the time to an integer circle, with laser or electron beam steel heading end is welded on the steel band, solder joint is shown in the pore of Fig. 2.Then with steel band round and round tightly on cylinder, after the full number of turns, with the termination be welded in steel band from one's body.On punch press, go out perforation then by tooth pitch, the trapezoidal (see figure 2) of the end surface shape in hole such as tooth bar, the burr of steel band is just in time fastened to each other, thus, has just made the multilayer steel band that this transmission is used with a steel band.
The structure of big small pulley is the same.Fig. 4～Fig. 6 shows the structure situation that belt wheel is put by view.Be involute on the theory of tooth form of belt wheel, it is the same with tooth bar with the engagement and the involute gear of steel band, generally will put the circular arc that wide curve approximation is 20 ° of pressure angles, and the steel band hole is 20 ° a skew lines.Belt wheel generally is pressed into the steel plate of 1～2mm, is welded in then on the central sleeve, and doing on the belt wheel has the external cylindrical surface of being wider than width of steel band, is used for stablizing and holds steel band (Fig. 5).When a large amount of production, belt wheel also can be designed as integral body, once goes out.
