Description
Technical field
The utility model relates to climbing device, particularly relates to a kind of ratchet-gear wheel rotating disk roller one-way locking mechanism.
Background technology
Lifting table, as a kind of elevator machinery, is widely used in the various workplaces such as logistics, carrying, assembling, city parking system, off-shore oil field.Its main function relies on driver train and lifting mechanism by object up-down to differing heights.Lifting mechanism has the character of rigidity and tenderness, according to the difference of lifting mechanism attribute, can be divided into 3 classes: 1. rigidity lifting mechanism, mainly utilizes the rigidity characteristics of mechanism to carry out direct jacking or propelling movement to platform; 2. flexible lifting mechanism, mainly through the flexible member such as steel rope, chain with the lifting of the mode implementation platform of towing; 3. hard and soft pair of attribute lifting mechanism, has integrity properties when this type of mechanism carries out lifting operation, then shows flexible attribute rigidity lifting mechanism and comprise several mechanism forms such as pinion and rack, plunger mechanism, scissors mechanism and screw mechanism when not working.Wherein pinion and rack comprises rack mechanism and gear mechanism, and tooth bar is arranged on spud leg, and every toothed rack is to there being several miniature gearss.Power passes to miniature gears by gear reducer, thus drives lifting platform.Gear-rack type lifter structure has the advantages such as work is continuous, rising or falling speed is fast, simple to operate, synchronism is good, and meanwhile, pinion and rack is easy to platform leveling and locates more accurate.But due to price, manufacture difficulty is large, is unfavorable for self-locking, is mainly used in marine jack up lifting table simultaneously.
Now design a kind of ratchet-gear wheel rotating disk roller one-way locking mechanism according to pinion and rack.
Summary of the invention
The purpose of this utility model is according to the feature of type of drive in existing pinion and rack and the deficiency of existence, ratchet-gear wheel rotating disk roller one-way locking mechanism is designed according to pinion and rack, this mechanism have in rack pinion process work continuously, rising or falling speed is fast, simple to operate, synchronism is good, simultaneously to the reduction of manufacture, setting accuracy, and there is the feature of reverse self-locking.
For achieving the above object, the technical scheme that the utility model adopts is: mainly comprise rotary disk, cylindrical roller, antifriction-bearing box, arc-shaped rack; Rotary disk is connected with cylindrical roller by antifriction-bearing box, and cylindrical roller engages with arc-shaped rack.
By such scheme, described rotary disk central axis place is provided with centre hole, the keyway for coordinating transmission with motor is provided with in hole, on rotary disk, has inner ring hole simultaneously, can be used to alleviate rotary disk quality and save material, be evenly equipped with some cycle holes be connected with cylindrical roller in outer ring simultaneously.
By such scheme, described arc-shaped rack is provided with some arc-shaped gears, and antifriction-bearing box is gauge member.
By such scheme, described rotary disk axle center place is designed with the keyway be connected with motor, rotary disk and arc-shaped rack are at same plane, rotary disk circumferencial direction is uniformly distributed some cylindrical rollers, cylindrical roller is connected with rotary disk by antifriction-bearing box, and cylindrical roller curved surface engages with the contoured surface of arc-shaped rack.Antifriction-bearing box can the displacement in fixed cylinder roller axis direction, but the circumference not affecting cylindrical roller is rotated.
The utility model, owing to have employed technique scheme, has that transferring power is large, efficiency is high, the characteristic of stable working, simultaneously to manufacturing, the reduction of setting accuracy, and there is the advantage of reverse self-locking.
Accompanying drawing explanation
Fig. 1 is overall appearance structure front elevation of the present utility model.
Fig. 2 is overall appearance structure side view of the present utility model.
Fig. 3 is overall appearance structure back view of the present utility model.
In figure: 1. arc-shaped rack, 2. rotary disk, 3. centre hole, 4. keyway, 5. arc-shaped gear, 6. cylindrical roller, 7. cycle hole, 8. inner ring hole, 9. antifriction-bearing box.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, arc-shaped rack 1, rotary disk 2, cylindrical roller 6 and antifriction-bearing box 9 is mainly comprised; Rotary disk 2 is connected with cylindrical roller 6 by antifriction-bearing box 9, and cylindrical roller 6 engages with arc-shaped rack 1.
By such scheme, described rotary disk 2 is provided with centre hole 3, is provided with the keyway 4 for coordinating transmission with motor in hole, has inner ring hole 8 on rotary disk simultaneously, can be used to alleviate rotary disk quality and save material, be evenly equipped with some cycle holes 7 in outer ring simultaneously.
By such scheme, described arc-shaped rack 1 is provided with some arc-shaped gears 5 with it, and antifriction-bearing box 9 is gauge member.
By such scheme, described rotary disk 2 axle center place is designed with the keyway 4 be connected with motor, rotary disk 2 and arc-shaped rack 1 are at same plane, rotary disk 2 circumferencial direction is uniformly distributed some cylindrical rollers 6, cylindrical roller 6 is connected with rotary disk 2 by antifriction-bearing box 9, and cylindrical roller curved surface engages with the contoured surface of arc-shaped rack 1.Antifriction-bearing box 9 can the displacement in fixed cylinder roller axis direction, but the circumference not affecting cylindrical roller 6 is rotated; On the contoured surface of thus cylindrical roller 6 arc-shaped gear 5 on arc-shaped rack 1, diriven motion is for rolling, and friction is therebetween friction of rolling, 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 rotary disk 2 axle center place, rotary disk 2 is driven to rotate, the cylindrical roller 6 be connected on rotary disk 2 by antifriction-bearing box 9 also will around rotary disk 2 center axis thereof, on arc-shaped rack 1, the contoured surface of arc-shaped gear 5 contacts with cylindrical roller 6 curved surface on rotary disk 2, cylindrical roller 6 is forced to roll on the profile of arc-shaped rack 1, both produce relative motion, if fixed by arc-shaped rack 1, then rotary disk upwards climbs.
