Abstract
The utility model provides a kind of agricultural seeding machine special-purpose driving-chain.It is formed by connecting by inner link and outer link, comprise carrier bar in inner link and the outer link, carrier bar is provided with pin-and-hole, also be provided with the bearing pin that is inserted in the pin-and-hole in the chain link, be enclosed within the outer sleeve of bearing pin, to be enclosed within sleeve outer and be in the roller between the pitch chain plate, the chain pitch of chain link is 30.05 to 30.50 millimeters, and the length of roller is 15.17 to 15.60 millimeters.The utility model cooperates with sprocket wheel rationally, the intensity height, and ensuring smooth transmission operates steadily, and vibrates for a short time, and the bearing capacity ability is big, and is not fragile, long service life.
Description
Technical field
The utility model relates to the special-purpose driving-chain of agricultural seeding machine.
Background technology
Original agricultural seeding machine driving-chain adopts the cast iron manufacturing, and its structure is adjacent two to save the buckle piece and realize transmission, low precision, and transmission is dumb, when transmission, cause hooked scarf to break off relations easily, the machine stall, and also intensity is relatively poor, use inconvenience, damage easily, service life is short.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ensuring smooth transmission, the special-purpose driving-chain of agricultural seeding machine easy to use.For this reason, the utility model is by the following technical solutions: it is formed by connecting by inner link and outer link, comprise carrier bar in inner link and the outer link, carrier bar is provided with pin-and-hole, it also is provided with the bearing pin that is inserted in the pin-and-hole, be enclosed within the outer sleeve of bearing pin, to be enclosed within sleeve outer and be in the roller between the pitch chain plate, the chain pitch of chain link is 30.05 to 30.50 millimeters, and the length of roller is 15.17 to 15.60 millimeters.
Because adopt technique scheme, the utility model cooperates with sprocket wheel rationally, the intensity height, ensuring smooth transmission operates steadily, and vibrates for a short time, and the bearing capacity ability is big, and is not fragile, long service life.
In the utility model, but interference fit between sleeve and the inner link carrier bar, but also interference fit between the carrier bar of outer link and the bearing pin, and at bearing pin two riveted, an end of bearing pin is provided with pin-and-hole in the connecting link, is inserted with split pin in the pin-and-hole.So not only ensuring smooth transmission, and be connected firmly and be difficult for flake, dismounting is easy to maintenance.Described bearing pin is made by low-alloy structural steel, and through carburizing thermal treatment, carrier bar is made by structural carbon steel.Like this, have higher tensile strength and fatigue resistance.

Embodiment
With reference to accompanying drawing.The utility model is formed by connecting by inner link 10 and outer link 20, comprise carrier bar 11,21 in inner link and the outer link, carrier bar is provided with pin-and-hole 12, it also is provided with the bearing pin 2 that is inserted in the pin-and-hole, be enclosed within the outer sleeve 4 of bearing pin, to be enclosed within sleeve outer and be in joint and connect roller 5 between the carrier bar, the chain pitch L of chain link
aBe 30.05 to 30.50 millimeters, the length L of roller
bIt is 15.17 to 15.60 millimeters.
In the utility model, sleeve only passes the pin-and-hole of inner link, like this, interference fit between the carrier bar 11 of sleeve and inner link, interference fit between the carrier bar 21 of outer link and the bearing pin, and at bearing pin two riveted.
Described bearing pin is made by low-alloy structural steel, and through carburizing thermal treatment, carrier bar is made by structural carbon steel.
In chain, wherein a joint outer link is as connecting link 30, and drawing reference numeral 8 is for connecting the split pin that chain is used, and an end riveted of bearing pin in the connecting link, the other end are provided with the pin-and-hole that cooperates with split pin, and split pin is inserted in this pin-and-hole.
