Abstract
The utility model relates to an inner star wheel with a trough on an inner circle for an automobile drive shaft. The inner star wheel comprises the inner circle which is matched with the automobile drive shaft, wherein the annular trough is formed on the hole inner wall of the inner circle; the top side of the trough is axially parallel to the inner circle; and a 108 DEG of angle is formed between one lateral side of the trough and the top side. The inner star wheel has the advantages that: the inner star wheel is firmly connected with the automobile drive shaft, is more convenient to assemble and disassemble and can be used for inner star wheels in various models.
Description
Technical field
The utility model relates to a kind of star-wheel that is used for truck drive shaft, relates in particular to the interior circle of this star-wheel.
Background technique
Structures such as the tradition transmission shaft is connected with star-wheel, and excessive for preventing moment of torsion, the star-wheel when load is overweight comes off, and adopts the end face location, and fastening piece is locked; But owing to receive the influence of alternation effect, can produce friction, contact and easy to wear the gap occurs and causes looseningly, and killing of fastening piece can't be dismantled, and when maintenance, can only use destructive the dismounting or whole replacing.
The model utility content
The utility model technical issues that need to address have provided a kind of star-wheel that is used for the interior round belt draw-in groove of truck drive shaft, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme:
The utility model comprises: the interior circle that matches with truck drive shaft; The draw-in groove of a ring-type is set on the hole inwall of circle in described; The top margin of said draw-in groove and the parallel to an axis of interior circle; Be 108 degree between one side of said draw-in groove and the top margin.
Compared with prior art, the beneficial effect of the utility model is: it is firm to be connected with truck drive shaft, installs and removes conveniently, can be used in the star-wheel of various models.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the I enlarged diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Visible by Fig. 1, Fig. 2: the utility model comprises: the interior circle 1 that matches with truck drive shaft; The draw-in groove 2 of a ring-type is set on the hole inwall of circle 1 in described; The top margin 4 of said draw-in groove 2 and the parallel to an axis of interior circle 1; Be 108 degree between one side 3 of said draw-in groove 2 and the top margin 4.
The bottom of the bi-side of its draw-in groove and star-wheel body is designed to 90 degree right angles and 18 degree oblique angles respectively in the utility model, when star-wheel processing endoporus, accomplishes together, and is time saving and energy saving, need not to increase any frock, also do not increase manufacturing procedure;
When adopting the utility model work, circlip is inserted in the space of this sealing, by the unidirectional qualification of the axially locating of transmission shaft; 90 degree right angles directly carry from the fierce impulsive load of torque direction (postive direction), rely on the strength of draw-in groove, and transmission shaft and star-wheel combine all the time; Play effect safely and reliably; Then as dismounting maintenance usefulness, as long as from axial (in the other direction) application of force, the transmission shaft band back-up ring and will from draw-in groove, be skidded off smoothly at 18 degree oblique angles; The convenient cleaning and replacing can be used in the steering gear of various models.
Claims (1)
1. star-wheel that is used for the interior round belt draw-in groove of truck drive shaft comprises: the interior circle that matches with truck drive shaft; It is characterized in that: the draw-in groove that a ring-type is set on the hole inwall of circle in described; The top margin of said draw-in groove and the parallel to an axis of interior circle; Be 108 degree between one side of said draw-in groove and the top margin.
