Abstract

The utility model discloses an angle redirector for a car, which is composed of a case, a bevel gear, and a gear shaft. A double-layer bearing is arranged on the gear shaft, and a clamping thread bush is arranged on the double-layer bearing, such a structure can thoroughly solve the axial serial motion caused when the gear shaft is shocked by a larger torque; meanwhile, a double-port oil seal is adopted so as to avoid products leaking oil radically. The angle redirector has simple structure and convenient installation, is secure, and can reduce the production cost greatly.

Description

Automobile angle commutator

Technical field:

The utility model relates to a kind of commutator, particularly relates to a kind of angle commutator of using on the heavy carrier that is used in.

Background technique:

According to relevant literature search, the employed automobile of China's heavy-duty car angle commutator at present, major part is to rely on import, the angle commutator price comparison costliness of import when particularly using, needs a large amount of products-supplys, in case be in short supply, will seriously influence the production of automobile.And the angle commutator of import in actual use, also is easy to occur the phenomenon of leakage of oil, and particularly under the bigger situation of moment of torsion, it is loosening snap ring also can to occur, takes off hidden danger such as to split.

Summary of the invention;

The purpose of this utility model will provide the angle commutator of a kind of automobile exactly, and it not only can fundamentally solve the existing defective of imported product, simultaneously, can also save production cost in large quantities, shortens the production time.The purpose of this utility model is to realize like this, automobile is made up of casing, bearing, bevel gear, gear shaft with the angle commutator, it is characterized in that: above described bevel gear, be provided with double-deck bearing respectively, adopt gland nut to be tightened on the top of casing on the described double-deck bearing; Be embedded with the twoport oil sealing at described gland nut, be provided with dust-proof cover on the top of gland nut and casing.The utility model is simple in structure, easy for installation, can prevent the gear axial motion that bevel gear can produce when being subjected to than high pulling torque very easily, and the angle commutator is when work, owing to having adopted the twoport oil sealing, so can not produce any oil leakage phenomenon.

Description of drawings:

Fig. 1 is the utility model structural representation;

1. dust-proof cover, 2. gland nut, 3. bearing, 4. casing, 5. gear shaft,

6. twoport oil sealing, 7. plug cock bolt, 8. flat key, 9. bevel gear.

Embodiment;

The utility model is described in further detail below in conjunction with accompanying drawing;

In the drawings, the utility model automobile is made up of casing 4, bearing 3, bevel gear 9, gear shaft 5 with the angle commutator, it is characterized in that: above described bevel gear 9, be provided with double-deck bearing 3 respectively, adopt gland nut 2 to be tightened on the top of casing 4 on the described double-deck bearing 3; Be embedded with twoport oil sealing 6 at described gland nut 2, be provided with dust-proof cover 1 on the top of gland nut 2 and casing 4.During concrete enforcement, one rooted tooth wheel shaft of angle commutator is a power intake, another root is a clutch end, the internal structure of two rooted tooth wheel shafts is identical, when power from input end through gear shaft when being delivered on another rooted tooth wheel shaft, owing to adopted double-deck design bearing, made gear shaft can not have any throw of eccentric; Equally,, can bear bigger moment of torsion owing to adopted double-deck design bearing, and the generation that does not produce any card machine phenomenon; Above double-deck bearing, adopted gland nut to be tightened on the top of casing, its objective is the axial motion of further locking axle sleeve, and keep the precision of gear shaft rotation; Inner ring at gland nut is provided with the twoport oil sealing, can prevent leaking of lubricant oil in the casing effectively, has thoroughly solved the phenomenon that leakage of oil appears in Vintage Product easily.The utility model can bear bigger moment of torsion, does not have any noise during running, and rotation can reduce the cost of production of auto vendor flexibly significantly.

Claims

1. automobile is made up of casing (4), bearing (3), bevel gear (9), gear shaft (5) with the angle commutator, it is characterized in that: be provided with double-deck bearing (3) respectively in the top of described bevel gear (9), described double-deck bearing (3) is gone up and is adopted gland nut (2) to be tightened on the top of casing (4); Be embedded with twoport oil sealing (6) at described gland nut (2), be provided with dust-proof cover (1) on the top of gland nut (2) and casing (4).
