Abstract
The utility model belongs to the technical field of offset printing machinery, a non - round gear revolve speed change mechanism of offset press variable speed paper feeding is related to, including interlock in proper order be located upper portion defeated paper tape gear, be located the non -circular gear at middle part and be located the balance gear of lower part, defeated paper tape gear, non -circular gear and balance gear all include the teeth of a cogwheel and tooth's socket, the teeth of a cogwheel and tooth's socket are level and smooth ARC structure and smooth connection each other. Compared with the prior art, the utility model has the advantages of the gear is longe -lived, and work sound is little.
Description
Technical field
The utility model belongs to offset printing field of mechanical technique, and the non-circular gear relating to a kind of offset press speed change paper feeding rotates gear.
Background technology
The non-circular gear of common offset press speed change paper feeding rotates gear, and gear is conventional rectangular gear, and shortcoming is that operating sound is large, and the gear teeth that work long hours consume is large, and precision diminishes gradually.The usual defeated paper amount of offset press is at about 18000 per hour, i.e. each second about 5, the very easily loss gear that runs up for a long time causes damage, and phenomenon occurs to cause that pause is got stuck etc.
Summary of the invention
The purpose of this utility model is, provide a kind of non-circular gear of offset press speed change paper feeding to rotate gear, have operating sound little, gear consumes little feature.
In order to achieve the above object, the non-circular gear that the utility model provides a kind of offset press speed change paper feeding rotates gear, comprise the superposed defeated paper tape gear be engaged successively, the non-circular gear being positioned at middle part and be positioned at the balance gear of bottom, described defeated paper tape gear, non-circular gear and balance gear include the gear teeth and teeth groove, and the described gear teeth and teeth groove are level and smooth globoidal structure and adjacent flat slip.
All gear teeth and teeth groove are level and smooth globoidal structure, and between gear and gear during mutual transmission, mode of touching each other is for exempting from touching, and touching area is very large, and there is not the touching of rigidity tip, do not damage the gear teeth, operational sound is little simultaneously, and mechanical oscillation are little.
Preferably, the described gear teeth are positioned at and gullet surface is coated with lubricating oil.
Preferably, described defeated paper tape gear and non-circular gear, touch without breakpoint between non-circular gear and balance gear.
Compared with prior art, the beneficial effects of the utility model are:
Gear life is long, and operational sound is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the non-circular gear rotation gear of the offset press speed change paper feeding of prior art
Fig. 2 is the structural representation of the non-circular gear rotation gear of offset press speed change paper feeding of the present utility model.
Fig. 3 is that non-circular gear of the present utility model rotates the gear teeth of gear and the details enlarged drawing of teeth groove.
Wherein 1 is defeated paper tape gear;
2 is non-circular gear;
3 is balance gear;
4 is the gear teeth;
5 is teeth groove.
Detailed description of the invention
With reference to Fig. 2, the non-circular gear that this embodiment describes a kind of offset press speed change paper feeding rotates gear, comprise the defeated paper tape gear 1, non-circular gear 2 and the balance gear 3 that are engaged successively up and down, the gear teeth 4 and the teeth groove 5 of each gear are level and smooth globoidal structure, and in smoothing junction between adjacent teeth 4 and teeth groove 5, overall formation one is without break curved surface.During rotation, middle non-circular gear 2 uniform rotation, speed change gyration done by the defeated paper tape gear 1 of the top of engaging with middle non-circular gear 2, thus realizes the defeated paper of speed change.Speed change gyration also done by the following balance gear 3 engaged with middle non-circular gear 2, and its effect is that balance non-circular gear 2 rotates the uneven torque caused, and improves the power performance of rotating.Each gear surface is coated with lubricating oil simultaneously, reduces friction.In order to optimize the way of contact between each gear further, defeated paper tape gear 1 and non-circular gear 2, between non-circular gear 2 and balance gear 3 without breakpoint touching, also on every bit another gear that must corresponding touch mutually certain a bit.
Claims (3)
1. the non-circular gear of an offset press speed change paper feeding rotates gear, comprise the superposed defeated paper tape gear be engaged successively, the non-circular gear being positioned at middle part and be positioned at the balance gear of bottom, described defeated paper tape gear, non-circular gear and balance gear include the gear teeth and teeth groove, it is characterized in that, the described gear teeth and teeth groove are level and smooth globoidal structure and adjacent flat slip.
2. non-circular gear according to claim 1 rotates gear, it is characterized in that, is positioned at the described gear teeth and gullet surface is coated with lubricating oil.
