Description
Technical field
This utility model relates to reducing gear technical field, particularly relates to a kind of small ep reductor.
Background technology
The widely used RV decelerator of robot joint speed reducer and harmonic speed reducer.Owing to processing and the assembly precision of part are required high by RV decelerator, existing universal machine tools are difficult to high efficiency processing, it is necessary to expensive special purpose machine tool, thus manufacturing cost is higher.Harmonic speed reducer relies on displacement transfer power and the motion of flexbile gear, and flexbile gear material requirements is high, the life-span is shorter, and can not transmit bigger moment of torsion.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of small ep reductor, not only compact conformation, transmission speed ratio is big, and the concentric transmission of input and output, transmission moment of torsion is big, there is higher transmission accuracy and higher mechanical efficiency, be particularly suitable for robot joint speed reducer.
Technical solution of the present utility model:
Small ep reductor includes planetary wheel carrier, body that described planetary wheel carrier includes dish type and the output axle journal extended by its center, and the circumference of described body is formed with angularly equidistant through hole；By bearing planet wheel spindle in described through hole, the two ends of described planet wheel spindle are equipped with input planet gear and output planetary gear, the input central authorities of described planetary wheel carrier are equipped with central gear, and central gear engages with input planet gear, by central gear input power；The input of described planetary wheel carrier passes through bearing equipped with input ring gear, and input ring gear engages with input planet gear, described input ring gear is provided with output ring gear near outfan side by bearing, and output ring gear engages with output planetary gear, described output axle journal passes through bearing equipped with PTO drive disk, and PTO drive disk is fixed with output ring gear and is connected.
Preferably, described input ring gear is fixed with end cap near input side.
Compared to prior art, this utility model has the advantages that
1, having more compact construction and less volume, minimum volume can accomplish external diameter 77mm, thickness 44mm.
2, planetary wheel carrier being designed to ' T ' type structure, thus make the overall dimensions of planetary wheel carrier greatly reduce, manufacture difficulty decreases accordingly, and therefore, it is possible to more reasonably arrange and install bearing arrangement, and overall assembling and setting is more simple and convenient.
2, power shaft and output shaft are in same center of rotation, improve axial, radial direction bearing capacity, and transmission moment of torsion is big.
When 3, installing, power intake can with motor coaxle direct connection, and only one of which shoulder is as benchmark, therefore easy to install.
4, there is higher transmission accuracy and higher mechanical efficiency.Transmission efficiency and transmission speed ratio are better than RV decelerator.Transmission efficiency reaches more than 90%.Transmission speed ratio ranges up to 500-40.
5, there is power-off and shut down auto-lock function.After power-off is shut down, when outfan applies moment of torsion, reducing gear does not rotate, and band band-type brake motor therefore need not be selected as input power, and not only reliability is high, reduces use cost, and easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the first embodiment of this utility model,
Fig. 2 is the structure sectional view of this utility model planetary wheel carrier.
Detailed description of the invention
Accompanying drawings below 1,2 describes a kind of embodiment of the present utility model.
A kind of small ep reductor, including planetary wheel carrier 5, body 51 that described planetary wheel carrier 5 includes dish type and the output axle journal 52 extended by its center, the circumference of described body 51 is formed with angularly equidistant through hole 53；By bearing 14 equipped with planet wheel spindle 7 in described through hole 53, the two ends of described planet wheel spindle 7 are equipped with input planet gear 3 and output planetary gear 12, the input central authorities of described planetary wheel carrier 5 are equipped with central gear 1, and central gear 1 engages with input planet gear 3, by central gear 1 input power；The input of described planetary wheel carrier 5 passes through bearing 13 equipped with input ring gear 4, and input ring gear 4 engages with input planet gear 3, described input ring gear 4 is provided with output ring gear 6 near outfan side by bearing 8, and output ring gear 6 engages with output planetary gear 12, described output axle journal 52 passes through bearing 11 equipped with PTO drive disk 10, and PTO drive disk 10 is fixed with output ring gear 6 and is connected.
Described input ring gear 4 is fixed with end cap 2 near input side.
During work, first pass through the ring flange having on input ring gear 4 cylindrical and this utility model is fixed on joint of robot position, then motor coaxle is fixedly mounted on end cap 2, and make electric machine main shaft coaxially couple with central gear 1, central gear 1 is driven to rotate, central gear 1 revolves round the sun around input ring gear 4 while driving input planet gear 3 rotation, and then drive planetary wheel carrier 5 to revolve round the sun, revolve round the sun around output ring gear 6 while being simultaneously attached to output planetary gear 12 rotation on planet wheel spindle 7, revolved round the sun by planetary wheel carrier 5 and drive output ring gear 6 to rotate around output ring gear 6 revolution while output planetary gear 12 rotation, power is slowed down output by PTO drive disk 10.Achieving input and output coaxial transmission, compact conformation, deceleration speed ratio is big, and axially, radially bearing capacity is high, and transmission moment of torsion is big, and has higher transmission accuracy and higher mechanical efficiency.Particularly having power-off and shut down auto-lock function, not only reliability is high, and easy to maintenance.
Above-described embodiment, simply preferred embodiment of the present utility model, not for limiting this utility model practical range, therefore all equivalent variations done with content described in this utility model claim, all should include within this utility model right.
