Description
Technical field
The utility model relates to a kind of mechanical transmission mechanism, particularly relates to a kind of compound cycloid bilateral to incorgruous roller arc-shaped gear driving mechanism.
Background technique
Current Linear transmission mode is mostly turbine and worm transmission, screw nut driven, crank block transmission, rack pinion etc.Worm drive shortcoming is that transmission efficiency is lower, should not at high-power lower long continuous operation, and in order to anti-attrition is wear-resisting, worm gear gear ring need with valuable bronze manufacture, and cost is higher.Screw nut driven surface friction drag is large, and transmission efficiency is low.Crank block transmission is apart from limited, and transmission accuracy is low.Gear rack has the advantages that transferring power is large, efficiency is high comparatively speaking, and the life-span is long simultaneously, and stable working, reliability is high.But the manufacture of gear rack, installation precision require higher, and thus cost is also higher, can not ensure unidirectional movement.
Summary of the invention
The purpose of this utility model is for overcoming the deficiency that in existing pinion and rack, the kind of drive exists, there is provided a kind of compound cycloid bilateral to incorgruous roller arc-shaped gear driving mechanism, it has in rack pinion process, and biography work is continuous, rising or falling speed is fast, simple to operate, synchronism good, reduces the requirement to manufacture, installation precision simultaneously.
For achieving the above object, the technological scheme that the utility model adopts is:
Comprise composite rotation disk, cylinder rolling pin, rolling bearing, upper arc-shaped rack, arc lower tooth bar; Composite rotation disk is connected with cylinder rolling pin by rolling bearing, and upper arc-shaped rack, arc lower tooth bar engage with cylinder rolling pin; Composite rotation disc centre axis place is provided with center hole, is provided with the keyway for coordinating transmission with motor, is evenly equipped with some cycle holes be connected with cylinder rolling pin in composite rotation disk outer ring in hole.
By such scheme, described upper arc-shaped rack and arc lower tooth bar are equipped with some arc-shaped gears.
By such scheme, described composite rotation disk is connected to form by cylinder rolling pin by two single-decks, upper arc-shaped rack and arc lower tooth bar are between two single-decks of composition composite rotation disk, composite rotation disk circumference direction is uniformly distributed some cylinder rolling pin, and cylinder rolling pin curved surface engages with the contoured surface of upper arc-shaped rack and arc lower tooth bar respectively.
The utility model, owing to have employed technique scheme, has that transferring power is large, efficiency is high, the feature of stable working, reduces manufacturing, the requirement of installation precision simultaneously.

In figure: 1. go up arc-shaped rack, 2. composite rotation disk, 3. center hole, 4. keyway, 5. arc-shaped gear, 6. cylinder rolling pin, 7. cycle hole, 8. inner ring hole, 9. arc lower tooth bar.
Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, arc-shaped rack 1, composite rotation disk 2, center hole 3, keyway 4, arc-shaped gear 5, cylinder rolling pin 6, cycle hole 7, inner ring hole 8, arc lower tooth bar 9, rolling bearing is comprised.Composite rotation disk 2 is connected with cylinder rolling pin 6 by rolling bearing, and cylinder rolling pin 6 engages with upper arc-shaped rack 1 and arc lower tooth bar 9 respectively.Composite rotation disk 2 is provided with center hole 3, the keyway 4 for coordinating transmission with motor is provided with in hole, on composite rotation disk, there is inner ring hole 8 simultaneously, can be used to alleviate rotary disk quality and save material, be evenly equipped with the some cycle holes 7 be connected with cylinder rolling pin 6 in outer ring simultaneously.
Upper arc-shaped rack 1 and arc lower tooth bar 9 are equipped with some arc-shaped gears 5.
Composite rotation disk 2 axle center place is designed with the keyway 4 be connected with motor, upper arc-shaped rack 1 and arc lower tooth bar 9 are all between two single-decks forming rotary disk 2, composite rotation disk 2 circumferencial direction is uniformly distributed some cylinder rolling pin 6, and cylinder rolling pin 6 curved surface engages with the contoured surface of upper arc-shaped rack 1 and arc lower tooth bar 9 respectively.Rolling bearing can the displacement of fixed cylinder rolling pin axial direction, but the circumference not affecting cylinder rolling pin 6 is rotated; Thus diriven motion is for roll on upper arc-shaped rack 1 with the contoured surface of the arc-shaped gear 5 on arc lower tooth bar for cylinder rolling pin 6, and friction is therebetween rolling friction, can greatly reduce friction, and increases transmission efficiency.
The utility model operationally, first motor is by coordinating transmission to be imported into by power with the keyway 4 at composite rotation disk 2 axle center place, composite rotation disk 2 is driven to rotate, the cylinder rolling pin 6 be connected on composite rotation disk 2 by bearing also will around composite rotation disk 2 center axis thereof, upper arc-shaped rack 1 contacts with cylinder rolling pin 6 curved surface on composite rotation disk 2 with the contoured surface of arc-shaped gear 5 on arc lower tooth bar 9, cylinder rolling pin 6 is forced to roll on upper arc-shaped rack 1 with the profile of arc lower tooth bar 9, both produce relative movement, namely power and the incorgruous transmission transmission of motion bilateral is completed.
