Background technique
Current Linear transmission mode is mostly turbine and worm transmission, screw nut driven, crank block transmission, gear rack transmission etc.; Worm drive shortcoming transmission efficiency is lower, should not be in high-power lower long-term continuous operation, and wear-resisting for anti-attrition, worm gear gear ring need be with valuable bronze manufacture, and cost is higher; Screw nut driven surface friction drag is large, and transmission efficiency is low; Crank block transmission distance is limited, and transmission accuracy is low; Gear rack has the advantages that transferring power is large, efficiency is high comparatively speaking, and life-span while is long, stable working, and reliability is high; But manufacture, the installation precision of gear rack are had relatively high expectations, thereby cost is also higher, can not ensure unidirectional movement.
Summary of the invention
The purpose of this utility model is to solve the deficiency that in existing Linear transmission, the kind of drive exists, cause a kind of mechanism that utilizes bilateral rotating disk roller and sour jujube type tooth to realize unidirectional movement according to the gear rack kind of drive, this mechanism has that in gear rack transmission process, transferring power is large, efficiency is high, the characteristic of stable working, simultaneously to manufacturing, the reduction of installation precision, and there is the feature of reverse self-locking.
For achieving the above object, the technological scheme that the utility model adopts is: mainly comprise rotary disk, bilateral cylindrical roller, rolling bearing, bilateral sour jujube type tooth bar; Rotary disk is connected with bilateral cylindrical roller by rolling bearing, and bilateral cylindrical roller engages with bilateral sour jujube type tooth bar.
Press such scheme, described rotary disk central axis place is provided with center hole, in hole, be provided with the keyway for coordinate transmission with motor, on rotary disk, there is inner ring hole simultaneously, can be used to alleviate rotary disk quality and save material, being evenly equipped with some cycle holes that are connected with bilateral cylindrical roller simultaneously in outer ring.
Press such scheme, described bilateral sour jujube type tooth bar is provided with some sour jujube type teeth with it, and rolling bearing is standard piece.
Formed by floral axis, axle sleeve two-part by such scheme bilateral cylindrical roller, between two parts, pass through spline joint.
Press such scheme, described rotary disk axle center place is designed with the keyway being connected with motor, rotary disk is parallel with bilateral sour jujube type tooth bar, rotary disk circumferencial direction is uniformly distributed some bilateral cylindrical rollers, bilateral cylindrical roller is connected with rotary disk by angular contact bearing, and bilateral cylindrical roller curved surface engages with the contoured surface of bilateral sour jujube type tooth bar.Angular contact bearing can be fixed the displacement of bilateral cylindrical roller axial direction, but does not affect the circumferential rotation of bilateral cylindrical roller.
The utility model has been owing to having adopted technique scheme, has that transferring power is large, efficiency is high, the characteristic of stable working, simultaneously to manufacturing, the reduction of installation precision, and there is reverse self-locking.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, mainly comprise bilateral sour jujube type tooth bar 1, rotary disk 2, bilateral cylindrical roller 6 and angular contact bearing 9; Rotary disk 2 is connected with bilateral cylindrical roller 6 by rolling bearing 9, and bilateral cylindrical roller 6 engages with bilateral sour jujube type tooth bar 1.
Press such scheme, described rotary disk 2 is provided with center hole 3, is provided with the keyway 4 for coordinate transmission with motor in hole, has inner ring hole 8 simultaneously on rotary disk, can be used to alleviate rotary disk quality and save material, being evenly equipped with some cycle holes 7 simultaneously in outer ring.
Press such scheme, described bilateral sour jujube type tooth bar 1 is provided with some sour jujube type teeth 5 with it, and rolling bearing 9 is standard piece.
Formed by cylindrical roller axle body, cylindrical roller axle sleeve two-part by such scheme bilateral cylindrical roller 6, between two parts, pass through spline joint.
Press such scheme, described rotary disk 2 axle center places are designed with the keyway 4 being connected with motor, rotary disk 2 is parallel with bilateral sour jujube type tooth bar 1, rotary disk 2 circumferencial directions are uniformly distributed some bilateral cylindrical rollers 6, bilateral cylindrical roller 6 is connected with rotary disk 2 by angular contact bearing 9, and bilateral cylindrical roller curved surface engages with the contoured surface of bilateral sour jujube type tooth bar.Angular contact bearing 9 can be fixed the displacement of bilateral cylindrical roller axial direction, but does not affect the circumferential rotation of bilateral cylindrical roller 6; Thereby diriven motion is for rolling on the contoured surface of bilateral cylindrical roller 6 sour jujube type tooth 5 on bilateral sour jujube type tooth bar 1, friction is therebetween rolling friction, can greatly reduce friction, and increases transmission efficiency.
