Abstract
The invention relates to a simple combined gear. The simple combined gear is characterized by comprising a plurality of single-piece gear bodies which are formed through cold stamping and are of the same specification, and the single-piece gear bodies are sequentially stacked and fixedly connected. The simple combined gear is simple in structure, convenient to manufacture and produce and low in cost and is suitable for low-load occasions with low requirements for accuracy and transmission, a traditional gear machining method is changed, production efficiency is greatly improved, and production cost is saved.
Description
Technical field
The present invention relates to a kind of built up gear, specifically a kind of simple type built up gear that is applicable to the less demanding occasion use of transmission accuracy.
Background technique
Along with mechanical technique development, driving gear is widely used in various machines and mechanism, the features such as gear has and possesses compact structure, efficiency is high, long service life, but the processing cutting method of conventional gears only has form cutting and generating method.Form cutting is on milling machine, adopt milling cutter that cutting edge shape is identical with teeth groove both sides profile geometry by gear cutting machine one by one teeth groove carry out cutting, this method manufacturing efficiency is low, should not produce in enormous quantities.Generating method also claims generating cutting, is also a kind of the most frequently used method of current Gear Processing, as gear shaping, gear hobbing, roll flute etc.But in some low speed, transmitted power is little, transmission accuracy is low occasion, machinery is not high to the required precision of gear, if still use the gear that adopts said method to process, will cause the operation and maintenance cost of equipment larger, do not meet the maximized principle of company interest.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of simple type built up gear is provided, it is simple in structure, manufacture convenient for production and with low cost, it is suitable for and transmission less demanding low year occasion use low to precision, change the processing method of conventional gears, greatly enhance productivity, save production cost.
According to technological scheme provided by the invention: simple type built up gear, is characterized in that: comprise some cold stamping shaped same specification monolithic gears, some described monolithic gears superpose successively and are connected and fixed.
As a further improvement on the present invention, some described monolithic gears are by straight pin riveting.
As a further improvement on the present invention, the card of described monolithic gear is provided with along the through hole being circumferentially evenly arranged, and described straight pin is arranged in through hole, and straight pin both ends of the surface exceed the height≤1mm of gear face part.
the present invention compared with prior art, has the following advantages:
(1) machinery equipment is simple, and cost of production is lower.
(2) compare conventional gears processing, greatly save the production time, manufacturing efficiency is high.
(3) the undercut imagination of having avoided generating method Plays Gear Processing to occur because the number of teeth is not enough.
(4) structural principle is simple, less demanding to production and processing personnel specialty level.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, the simple type built up gear in embodiment is mainly comprised of three same specification monolithic gears 1, and three described monolithic gears 1 superpose successively and pass through straight pin 2 rivetings.
As shown in Figure 1, monolithic gear 1 in the present invention is the monolithic gear 1 obtaining by cold stamping mould, the card of monolithic gear 1 is provided with along the through hole being circumferentially evenly arranged, straight pin 2 is arranged in through hole, by riveting machine, three monolithic gears 1 are riveted together, the height that straight pin 2 both ends of the surface after requirement riveted joint exceed gear face part does not exceed 1mm.
Simple type Combinative pattern gear of the present invention is useful in low speed, transmitted power is little, transmission accuracy is low occasion, and it can realize the transmission agency of gear.Compare with gear hobbing with gear shaping, punching press Gear Production efficiency is high, and punching equipment is simple, not high to production operation personnel specialty requested knowledge, saves process time and cost, can realize the maximization of manufacturing enterprise's interests.
