Definitions
- the subject of the invention concerns a chain transmission used in machine drives.
- a book of M. Dudziak “String transmission”, WN PWN, Warsaw 1997, page 246-253 describes a chain transmission consisted of at least two sprockets partially encircled by a chain.
- a chain consists of a series of links connected through articulated joint.
- For correct positioning of the chain on the sprockets its slight overhang is required, which is adjusted periodically or continuously by use of a tensioner.
- the tensioner allows correct operation of the transmission when the chain lengthens in course of time, mainly because of abrasive wear of its elements.
- roller pitch chains consisting of alternately inner and outer links consisting of outer plates, pins, inner plates, sleeves and rollers.
- toothed roller chain composed of appropriately shaped plates, each of them having two protrusions on one of longer edges, which are teeth corresponding in form with the sprocket teeth and building a chain transmission together with a chain; the second edge of the longer edges of the plate is smooth.
- the plates have two holes in which pins connecting adjoining chain links are located.
- toothed sprocket having chain transmitting power which consists of links.
- the sprocket has teeth radially protruding and spreading in distance of chain links length.
- the chain has two rows of driving and driven alternately laid links which are connected by pins. Both rows of links are alternated along the chain, so that lines of links of second row are laid between links from adjoining lines of first row, and lines of links from first row are laid between links from adjoining lines of second row.
- Described solutions do not allow achieve the same rotational speed of toothed driving and driven sprockets of different diameters while transmitting power through one chain.
- a chain transmission which contains two toothed sprockets, a chain and a tensioner, where according to the invention the centre of pitch circle of the driven sprocket lays outside of the circle inscribed in the part of chain mating with the sprocket.
- the chain consists of links connected by pins, where each link contains plates connected by three pins, while the axis of one of the pins lays outside of the plane determined by axes of the remaining pins of the link.
- the chain transmission according to the invention allows achieves the same rotational speed of toothed sprockets of different diameters while transmitting power through one chain.
- the subject of the invention is shown in examples in drawings, where fig.1 performs scheme of the chain transmission, fig. 2 performs a chain link in axonometric projection, fig.3 performs view of a chain fragment.
- the transmission is located in one plane: a driving toothed sprocket 1_, driven toothed sprocket 2, tension roll 3, and chain 4.
- Sprockets 1 and 2 engage with each other by means of chain 4 encircling driving sprocket, tensioned and pressed against the driven sprocket 2 by tensioner 3, while the driving toothed sprocket 2 is not encircled by chain 4.
- Chain 4 consists of outer links 5 and inner links 6 laid alternately along the chain's 4 length.
- Each of links, 5 and 6, of chain 4 forms a pair of set parallel and triangle-like plates 7, connected together at their bases by two pins 8 and at their top by a pin 9. Between plates 7, rolls IQ are put onto two pins 8 and 9.
- Pins 8 at bases of plates 7 connect simultaneously two adjoining links 5 and 6 forming an articulated joint enabling to encircle sprocket 1 and tension roll 3.
- the centre of pitch circle S of the driven sprocket 2 lays outside of the circle inscribed in the part of chain 4 mating with the sprocket 2.
- the diameter of the inscribed circle equals to diameter of the tighten circle 3.
