Described roller drive wheel is characterized in that: at least one center is provided with the axis hole that is connected with a multiple key core relative fixed in this left and right spoke disc.
Described roller drive wheel is characterized in that: this axis hole inside edge is provided with tooth, and this roller drive wheel is located on this multiple key core by this shaft hole sleeve, the tooth engagement of the tooth of this axis hole inside edge and this multiple key core one end outer ledge.
In sum, roller drive wheel of the present utility model, be to utilize the roller of existing chain and the tooth that the assembling of the bearing pin in the middle of the roller replaces cylindrical gears, so just improved the degree of finish of the flank of tooth greatly, the noise in the column gear transmission, vibration and shock problem have been alleviated, and manufacturing process is simple, roller and bearing pin are standard piece, left and right spoke disc is the punching press sheet metal part, Pei Dui gear also can be the identical punching press gear sheet metal part of tooth pitch with it, but die sinking is produced in batches, and its kind of drive is identical with cylindrical gears, and means of fixation can be the riveted mode.
Now illustrate the progressive effect of roller drive wheel of the present utility model as follows:
1, instantaneous transmission ratio is constant;
2, gear range is big, can be used for speedup or deceleration;
3, the speed (the round circular velocity of dactylus) and the scope of transmitted power are big, can be used at a high speed (V＞40m/s), middling speed or the low speed (transmission of V＜25m/s); Power can be from less than 1W to 10
5KW;
4, transmission efficiency height, efficient can reach more than 99%;
5, compact structure, in light weight (with same gear mutually weight/power ratio be about 1/5), be applicable to closely transmission;
6, roller surface degree of finish very high (the roller surface roughness can reach Ra0.8, is equivalent to gear IT5 level), during transmission noise, vibration and impact little, power loss is little;
7, simple, the cost lower (compare cost with same gear and can reduce by 50%) of manufacturing process can be produced in batches;
8, little to centre distance receptance, assemble and keep in repair easy.

[embodiment]
As shown in Figure 1, the utility model provides a kind of roller drive wheel 10, and it is to cooperate an existing gear 30 to realize the transmission effect.This roller drive wheel 10 comprises: left and right spoke disc 11,12, several are arranged at the bearing pin 13 between left and right spoke disc 11,12 edges, and several are set in the roller 14 on this each bearing pin respectively.
Shown in Fig. 2,3,4, this left and right spoke disc the 11, the 12nd, the coaxial and parallel two circular sheet metal parts that are oppositely arranged, the mutual closing in the middle part of this two sheet metal part is fixed, and has certain distance between its circumferential edges, can hold this roller 14 to be arranged on wherein; The edge of this left and right spoke disc 11,12 is equally spaced, and pin-and-hole 15 quantity that these two spokes disc, 11,12 edges are provided with are identical around being provided with several pin-and-holes 15, and the position is corresponding mutually; At least one center is provided with one and is used for the axis hole 16 that is connected with a multiple key core 20 in this two spokes disc 11,12, these axis hole 16 inside edges are provided with tooth 161, so that with these multiple key core 20 sheathed installations, and with tooth 21 engagement of these multiple key core 20 1 end outer ledges, these roller drive wheel 10 relative these multiple key cores 20 are fixed.
Shown in Fig. 1,3,4, this each bearing pin 13 is a cylindrical body, and riveted is arranged on this two spokes disc, 11,12 edges by two pin-and-holes 15 that are oppositely arranged on the left and right spoke disc respectively at these each bearing pin 13 two ends; Because this each bearing pin 13 is an interference fit with this each pin-and-hole 15, so not these each pin-and-hole 15 generation rotations relatively of this each bearing pin 13.
Shown in Fig. 1,4, this each roller 14 is a hollow cylinder, and each roller 14 surface roughness has greatly improved than original gear, and (roller 14 surface roughnesses can reach Ra0.8, be equivalent to gear IT5 level), this each roller 14 is set in respectively on this each bearing pin 13, between this each roller 14 and this each bearing pin 13 is Spielpassung, and the axial length of this roller 14 is slightly less than the distance between these left and right spoke disc 11,12 inboards, so that this roller 14 can rotate relative to this bearing pin 13.
As shown in Figure 5, this roller drive wheel 10 be arranged in parallel with gear 30, and roller 14 engagements of the gear teeth 31 of this gear 30 and this roller drive wheel 10.When this roller drive wheel 10 is worked with gear 30 transmissions, the gear teeth 31 of this gear 30 in regular turn with roller 14 engagement of this roller drive wheel, because that to be outer surface degree of finish higher is cylindrical for the roller 14 of this roller drive wheel 10, and can rotate relative to this bearing pin 13, therefore, when the gear teeth 31 of gear 30 impact these roller 14 surfaces, this roller 14 rotatable with reduce and these gear teeth 31 between friction, and take advantage of a situation these gear teeth 31 imported engagement accurately.Because this roller 14 is higher cylindrical of outer surface degree of finish, and rotatable with reduce and these gear teeth 31 between friction, so, when roller drive wheel 10 of the present utility model cooperates transmission work with gear 30, can effectively reduce the frictional loss of gear 30, so prolong each workpiece working life, alleviate operating noise.Simultaneously, because roller drive wheel 10 of the present utility model, its left and right spoke disc 11,12, bearing pin 13, and roller 14 is the standard design size, is convenient to make, change, and have and make and the cheap advantage of installation cost.
In sum, roller drive wheel 10 of the present utility model mainly is to utilize several bearing pins 13 and roller 14 to cooperate two spoke discs, 11,12 secure bond, realize transmission to cooperate with gear 30, such design is not limited to the external gear transmission, equally applicable to the internal gear transmission, and traditional type of belt drive such as roller transmission wheel and rack transmission.
