The model utility content:
The purpose of this utility model is that a kind of simple in structure, transmission of power is steady, precision is high many shock waves cylindrical roller variable-speed bearing is provided at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technological scheme:
Many shock waves cylindrical roller variable-speed bearing, it includes internal tooth axle, transmission circle, external toothing, offer internal tooth in the external toothing, the internal tooth axle is provided with external tooth, transmission circle one side is along the radially guide groove that circumferentially has five equilibrium, radially be placed with cylindrical roller in the guide groove, cylindrical roller meshes with the internal tooth of external toothing and the external tooth of internal tooth axle respectively.
Be connected with bearing between described internal tooth axle and the transmission circle, internal tooth axle one end is provided with the step axle, sheathed bearing on the step axle.
Described internal tooth axle offers axis hole, and axis hole is provided with keyway.
Offer attachment hole on the described transmission circle end face.
Also be provided with raceway and steel ball between described external toothing and the transmission circle.
The described internal tooth axle number of teeth is not less than 3, and the external toothing number of teeth is not less than 3.
The utility model beneficial effect is: the utility model includes internal tooth axle, transmission circle, external toothing, offer internal tooth in the external toothing, the internal tooth axle is provided with external tooth, the external toothing number of teeth is not less than the internal tooth axle number of teeth, transmission circle one side is along the radially guide groove that circumferentially has five equilibrium, radially be placed with cylindrical roller in the guide groove, cylindrical roller meshes with the internal tooth of external toothing and the external tooth of internal tooth axle respectively, replace of the prior art pair of roller tappet with cylindrical roller simple in structure, simplified transmission process, reduced wearing and tearing, transmission of power is steady, precision is high, the life-span is long.

Fig. 2 is the sectional view of A-A direction among Fig. 1
Fig. 3 is the utility model embodiment 2 a structural representation
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Be connected with bearing 4 between internal tooth axle 1 and the transmission circle 2, internal tooth axle 1 one ends are provided with step axle 12, sheathed bearing 4 on the step axle 12, and bearing 4 is played a supporting role, and makes transmission circle 2 stability of rotation.Internal tooth axle 1 offers axis hole 13, and axis hole 13 is provided with keyway 14, is easily installed on the outer drive shafts.Offer attachment hole 23 on transmission circle 2 end faces, make things convenient for being connected of transmission circle 2 and exterior part.Also be provided with raceway 5 and steel ball 6 between external toothing 3 and the transmission circle 2, reduce the friction of transmission circle 2 and external toothing 3, make transmission circle 2 and external toothing 3 rotate more steady mutually.
In the present embodiment, internal tooth axle 1 number of teeth is 5, and external toothing 3 numbers of teeth also are 5, and guide groove 21 quantity of transmission circle 2 are 10.
Transmission principle of the present utility model: when external toothing 3 fixedly the time, drive internal tooth axle 1, cylindrical roller 22 is done radial motion in the radially guide groove 21 of transmission circle 2, this motion is subjected to the constraint of external toothing 3, cylindrical roller 22 is when doing radial motion, make transport motion with internal tooth axle 1, this motion drives transmission circle 2, transmission circle 2 is done with internal tooth axle 1 coaxial line, is rotated with the deceleration that turns to, velocity ratio is that external toothing 3 numbers of teeth add internal tooth axle 1 number of teeth divided by internal tooth axle 1 number of teeth, plays a supportive role at this bearing 4 and 6 pairs of transmission circles 2 of steel ball; Drive transmission circle 2, internal tooth axle 1 is done with transmission circle 2 coaxial lines, with the speedup motion that turns to, the inverse when velocity ratio is gearing down.
According to relative motion principle, also can realize as follows axis and isoplanar motion: when fixed conveyor circle 2, drive internal tooth axle 1, external toothing 3 is done to rotate with the deceleration of internal tooth axle 1 counterturn, and velocity ratio is that external toothing 3 numbers of teeth are divided by internal tooth axle 1 number of teeth; Drive external toothing 3, internal tooth axle 1 is done to rotate the inverse when velocity ratio is gearing down with the speedup of external toothing 3 counterturns.
Fixedly during internal tooth axle 1, drive external toothing 3, transmission circle 2 is done and the external toothing 3 identical decelerations rotations that turn to, and velocity ratio is that external toothing 3 numbers of teeth add internal tooth axle 1 number of teeth divided by external toothing 3 numbers of teeth; Drive transmission circle 2, external toothing 3 is done to rotate the inverse when velocity ratio is gearing down with the transmission circle 2 identical speedups that turn to.
The utility model monnolithic case size is little, and is simple in structure, manufacturing process is simple; Replace of the prior art pair of roller tappet with cylindrical roller simple in structure 22 in the radially guide groove 21 in transmission circle 2, simplified the power transmission process, reduced wearing and tearing, transmission of power is steady, precision is high, the life-span is long, and gear range is big.
When using deceleration of the utility model do or speedup transmission, variable-speed bearing integral body directly can be packed in the main frame, do not need transmission case, main frame only need be reserved a mounting point, thereby make the host design arrangement convenience, simple in structure, shortened Transmitted chains, many high speed rotating parts in the main frame have been omitted, play the effect that improves host performance, can be implemented in simultaneously under the constant situation of main machine structure, by changing the variable-speed bearing of different drive ratios, just can change host parameter, adapt to the needs of main frame processed product or other functions change; Can also realize that the coaxial line difference turns to and rotate and do not change the mechanical transmission of velocity ratio.
