Abstract
The utility model relates to axial positioning devices for transmission shafts, in particular to a stop washer used for a round nut of a transmission shaft, and aims at solving the technical problem that after an existing stop washer guarantees that a round nut is screwed up according to specified torque, a tooth of an outer circle of the existing stop washer cannot be accurately bent into a stop groove of the round nut. The stop washer comprises the round nut in threaded connection with the transmission shaft, and a stop washer body matched with the round nut, an inner tooth matched with a key groove of the transmission shaft and outer teeth capable of being bent into a stop groove of the round nut are arranged on the stop washer body, and the number of the outer teeth can be calculated according to the following formula, namely n=[90/alpha]+2, wherein alpha can be calculated according to the following formula, namely alpha=b/dx180/Pix2, b refers to tooth width of the outer teeth, and d refers to diameter of the stop washer body. Probability that the outer teeth of the stop washer are smoothly bent into the stop groove of the round nut is increased, and assembling efficiency is improved.
Description
Technical field
The utility model relates to shaft part axial-positioning device, particularly the round nut lock washer of axial workpiece axially locating.
Background technique
Gear transmission, belt pulley transmission, sprocket driving, ratchet driver, generally for various mechanical transmission occasions.Realize the reliable location of all kinds of driving parts on axle, very crucial for the normal work of machine.
Round nut be positioned at rotating speed higher, bear larger axis to load situation under, apply more extensive.Loosening for preventing that round nut from occurring in rotary course, conventionally with lock washer, come locking.Fig. 1, Fig. 2 have provided the indication device that coordinates location on gear shaft 5 with round nut 4, lock washer 3, distance ring 2 with rolling bearing 1, wherein: the internal tooth 3.1 of lock washer 3 is inserted in the keyway 5.1 of gear shaft 5, on the outer ring of lock washer 3, a certain external tooth 3.2 bend in the locking groove 4.1 of round nut 4 smoothly, realizes locking.In actual using process, guaranteeing that round nut is after moment is tightened in accordance with regulations, the lock washer (as GB858) of prior art, it is smaller that a certain tooth of its cylindrical can bend into probability in the groove of round nut just smoothly.
Model utility content
The purpose of this utility model is intended to overcome the shortcoming of prior art, a kind of lock washer for transmission shaft round nut is provided, solve current lock washer and guaranteeing that round nut after moment is tightened in accordance with regulations, can not accurately bend into the technical problem in round nut locking groove by lock washer cylindrical one tooth smoothly.
The utility model is achieved through the following technical solutions:
A kind of lock washer for transmission shaft round nut, comprise: transmission shaft, the round nut being threaded with transmission shaft, the lock washer coordinating with round nut, described lock washer is provided with the internal tooth coordinating with the keyway of transmission shaft, described lock washer is provided with some external tooths of the locking groove that can bend into round nut, it is characterized in that: the number of teeth of described external tooth can be calculated as follows:
n＝［90/α］+2，
Wherein: n is the number of teeth, α is 2 of the external tooth facewidth and the angle of lock washer central point line, and α can be calculated as follows:
α=b/d×180/π×2，
Wherein: b is the external tooth facewidth, d is lock washer diameter.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, do not increasing under the prerequisite of production cost, by changing the relative angle of the lock washer external tooth number of teeth and each tooth, improving lock washer cylindrical one tooth and bent into smoothly the probability in round nut groove;
2, in large-scale mass production assembling, efficiency is high, reduces assembly cost;
3, reduced labor strength.
Accompanying drawing explanation
Fig. 1 is that round nut and lock washer are located schematic diagram on transmission shaft;
Fig. 2 is the A-A sectional drawing (lock washer and round nut, transmission shaft coordinate location schematic diagram) of Fig. 1;
Fig. 3 is the structural representation of lock washer.
Embodiment
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is further described.
As shown in Figure 1, 2, a kind of lock washer for transmission shaft round nut, comprise: transmission shaft 5, the round nut 4 being threaded with transmission shaft 5, the lock washer 3 coordinating with round nut 4, described lock washer 3 is provided with the internal tooth 3.1 coordinating with the keyway 5.1 of transmission shaft 5, and described lock washer 3 is provided with some external tooths 3.2 of the locking groove 4.1 that can bend into round nut 4, it is characterized in that: the number of teeth of described external tooth 3.2 can be calculated as follows:
n＝［90/α］+2，
Wherein: n is the number of teeth, α is 2 of the external tooth facewidth and the angle of lock washer central point line, and α can be calculated as follows:
α=b/d×180/π×2，
Wherein: b is the external tooth facewidth, d is lock washer diameter.
As shown in Figure 3, angle α is determined by external tooth facewidth b, each tooth relative position β 1, β 2, β 3 ..., along clockwise (or counterclockwise), be followed successively by n α (n=1 with the angle of the each axle of rectangular coordinate system, 2,3 ...), with each axle clamp angle be along clockwise direction: α, 2 α, 3 α, 4 α, 5 α, 6 α ..., the like.
By n=［ 90/ α ］+2, the known number of teeth depends on angle α, and the size of α is determined by the facewidth and diameter d, the maximum angle of swing that lock washer can not bend in round nut groove just smoothly depends on angle α, in the situation that diameter d is certain, the facewidth is narrower, and the probability bending into is smoothly larger.
Accompanying drawing 3 is based on packing ring GB858140 size design, and lock washer can not bend into the maximum angle of swing in round nut groove just smoothly
α=b/d×180/π×2＝13.5／165×180／π×2＝9.380
External tooth number of teeth n=［ 90/ α ］+2=90/9.38+2=11.
External tooth is along being followed successively by clockwise: 01,08,04,011,07,03,010,06,02,09,05.
Lock washer one external tooth bend into smoothly in round nut locking groove and refers to that round nut is by after specifying moment values to tighten, and on lock washer, a certain external tooth aligns with round nut locking groove just, and uses external force that external tooth on the lock washer of alignment is buckled in round nut locking groove.
The utility model greatly improves probability or the pole of rotation small angle that lock washer external tooth bend in round nut groove smoothly and can bend into smoothly, has greatly improved efficiency of assembling, particularly for the product of mass production.
