In figure: 1, gear; 2, the first wheel body; 3, the second wheel body; 4, axis hole; 5, keyway; 6, joint; 7, first gear teeth; 8, second gear teeth; 9, chute; 10, projection is strengthened; 11, support; 12, steel ball; 13, ring set; 14, bolt; 15, nut; 16, rope; 17, stationary axle; 18, tapped hole; 19, groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one: with reference to Fig. 1, the center of the present embodiment middle gear body 1 offers the axis hole 4 with keyway 5, gear 1 comprises the first wheel body 2 and the second wheel body 3, the end face of the first wheel body 2 is provided with and is formed with circumferentially shape between the first gear teeth 7, first wheel body 2 and the second wheel body 3 and to the annular groove 9 of axis hole 4 direction depression.In the present embodiment the first wheel body 2 and the second wheel body 3 one-body molded, and the first wheel body 2 is identical with size with the shape of the second wheel body 3, and like this, when face gear is used as pulley, the two ends of face gear can stress balance, more steadily.
The face gear of the present embodiment in use, first gear teeth 7 engage with spur gear or helical gear, when first gear teeth 7 have damage, existing face gear is generally directly discarded, but the face gear of the present embodiment is when first gear teeth 7 damage, face gear can be taken off, face gear is used as pulley, because chute 9 is low between the senior middle school of two ends, as long as rope 16 is embedded in chute 9, rope 16 would not depart from gear 1, again axis hole 4 is set on stationary axle 17, the diameter of stationary axle 17 is herein less than the diameter of axis hole 4, but the diameter of stationary axle 17 is also greater than the width of keyway 5, gear 1 can be rotated on stationary axle 17, pull one end of rope 16, rope 16 and chute 9 inwall produce stiction, and the stiction that rope 16 and the inwall of chute 9 produce is greater than the stiction of axis hole 4 and stationary axle 17, make gear 1 can rotate on stationary axle 17 like this, achieve the transmission of rope 16.
Further, described second wheel body 3 is provided with second gear teeth 8, and second gear teeth 8 are all identical with size with the shape of first gear teeth 7, so when first gear teeth 7 damage, gear 1 is disassembled and installs in the other direction again, can realize when first gear teeth 7 damage, second gear teeth 8 can continue to use, and extend the working life of face gear.Certainly, shape and the size of second gear teeth 8 and first gear teeth 7 also can be different, do not limit herein.
Embodiment two: as shown in Figures 2 to 4, in the present embodiment, the first wheel body 2 and the second wheel body 3 are for removably connecting, first wheel body 2 and the second wheel body 3 offer corresponding tapped hole 18, bolt 14 is fed through tapped hole 18 and coordinates with nut 15, thus the first wheel body 2 is fixedly connected with the second wheel body 3, certainly, also clamping or socket etc. can be adopted to be fixedly connected with mode, the present embodiment does not limit, first wheel body 2 comprises joint 6 in the form of annular discs, it should be noted that herein, the diameter of joint 6 is less than the diameter of the first wheel body 2, and joint 6 is connected to establishing with the second wheel body 3.
Further, joint 6 is arranged with support 11, support 11 is embedded with multiple and joint 6 to the steel ball 12 established, preferably, as shown in Figure 3, the outer side wall of joint 6 offers circumferentially shape and to the groove 19 of axis hole 4 direction depression, steel ball 12 can be placed in groove 19 and to roll around groove 19, support 11 is arranged with described steel ball 12 all to the ring set 13 established.
Like this, ring set 13 can be rotationally connected by steel ball 12 and joint 6, the face gear of the present embodiment in use, as shown in Figure 5, gear 1 is set on stationary axle 17, it should be noted that herein, with in embodiment one unlike, the present embodiment central axis hole 4 and stationary axle 17 are for being fastenedly connected, after like this rope 16 being set on ring set 13, pull one end of rope 16, stiction is produced between rope 16 and ring set 13, after ring set 13 is subject to the effect of power, opposing connections 6 rolls, because have steel ball between ring set 13 and joint 6, so the frictional force produced because rolling is very little, so can be more laborsaving when pulling rope 16.
The present embodiment and embodiment one unlike, the present embodiment middle gear body 1 self does not rotate, but by pulling rope 16 thus band moving ring sleeve 13 rotates, realizes the transmission of rope 16.
In addition, gear 1 is provided with outward extending reinforcement projection 10 in axis hole 4 edge.Strengthening projection 10 can make gear 1 increase with the surface of contact of stationary axle 17, and such gear 1 can be more firm with the connection of stationary axle 17.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
