Abstract
The invention discloses a cast double-tooth gear comprising a gear body and gear rings. The gear ring comprises a plurality of teeth. The center of the gear body is provided with a shaft hole. Four key grooves are arranged outside the shaft hole. The inner layer of the shaft hole is provided with inner gear rings more than the gear rings. The inner gear rings are equal to the gear rings in shape. An oil passage is arranged between the gear rings and the shaft hole; one end of the oil passage is provided with an oil hole; a filter screen is arranged between the gear body and the shaft hole; the filter screen is a multilayer stainless steel nickeled filter screen. The cast double-tooth gear is simple in structure and ingenious in design, has diverse transmission functions, is flexible in transmission, can be reliably connected, is low in wear loss, belongs to the technical field of gears, and is low in noise and long in service life.
Description
Technical field
The present invention relates to gear technique field, particularly relate to a kind of casting bidentate gear.
Background technique
Along with the development of each machinery industry of China, gear industry has obtained development fast as mechanical basic part industry, and industry size constantly expands, and has become industry largest in Chinese mechanical basic part.Gear transmission is modal a kind of mechanical transmission, and it is a kind of form of transmitting machine power and motion, has become indispensable transmission part at engineering goods middle gear, is engineering goods important foundation component.Existing gear generally only has a gear ring, with other driving component motion, in the process of motion, can produce heat, causes gear wear, and shorten working life, and transmission agency is single, also affected the precision of the flank of tooth simultaneously.
Summary of the invention
In order to overcome the deficiency in above prior art, the invention provides one and possess that gear wear is little, noise is little, working life is short, meanwhile, there are two gear rings, the casting bidentate gear of the advantage such as transmission agency is various.
The present invention takes following technological scheme to realize: a kind of casting bidentate gear, comprise gear body and gear ring, described gear ring comprises multiple teeth, described gear body interior center is provided with axis hole, described axis hole outside is provided with four keyways, described axis hole internal layer is provided with ring gear, described ring gear quantity is greater than the quantity of described gear ring, described ring gear is identical with described gear ring shape, between described gear ring and described axis hole, be provided with oil duct, oil duct one end is provided with oilhole, between described gear body and described axis hole, be provided with filter screen, described filter screen is multilayer stainless steel nickel plating filter screen.
Described gear ring cross section is quadrilateral.
Described key slot material is zinc-plated carbon steel, arranges symmetrically along the cylindrical of axis hole.
Described gear ring is identical with described ring gear thickness.
Between described gear ring, described axis hole, all scribble lubricant oil.
The present invention has following beneficial effect in sum: this product structure is simple, designs ingenious, easy to assembly quick.
1, possess two gear rings, transmission agency is various, and transmission is more flexible;
2, connect reliably, reduced wearing and tearing;
3, the noise while effectively reducing gear transmission;
4, there are four keyways, after damaging appears in a keyway, can use other keyway, do not affect gear and normally use.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, gear ring; 2, gear body; 3, filter screen; 4, filled with foam aluminum thing; 5, oil duct; 6, oilhole; 7, axis hole; 8, ring gear; 9, keyway.
Embodiment
As shown in Figure 1, a kind of casting bidentate gear, comprise gear body 2 and gear ring 1, described gear ring 1 comprises multiple teeth, described gear body interior center is provided with axis hole 7, described axis hole 7 outsides are provided with four keyways 9, described axis hole 7 internal layers are provided with ring gear 8, described ring gear 8 quantity are greater than the quantity of described gear ring 1, described ring gear 8 is identical with described gear ring 1 shape, between described gear ring 1 and described axis hole 7, be provided with oil duct 5, oil duct 5 one end are provided with oilhole 6, between described gear body 2 and described axis hole 7, be provided with filter screen 3, described filter screen 3 is multilayer stainless steel nickel plating filter screen.
Described gear ring 1 cross section is quadrilateral.
Described keyway 9 materials are zinc-plated carbon steels, arrange symmetrically along the cylindrical of axis hole.
Described gear ring 1 is identical with described ring gear 8 thickness.
This product possesses two gear rings, and transmission agency is various, and transmission is more flexible; There are four keyways, after damaging appears in a keyway, can use other keyway.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
