Technical solution of the present utility model: a kind of planetary gear speed reducing mechanism, including planetary wheel carrier, described By planet wheel spindle, input planet gear and output planetary gear, described planetary gear are installed on planetary wheel carrier The input central authorities of frame are provided with central gear, and central gear engages with input planet gear, by Heart gear input power；The input of described planetary wheel carrier is provided with input ring gear by bearing, and defeated Entering ring gear to engage with input planet gear, described input ring gear is pacified by bearing near outfan side Equipped with output ring gear, and output ring gear engages with output planetary gear；The output of described planetary wheel carrier End is provided with PTO drive disk by bearing, and described input ring gear is fixed with bearing near outfan side Seat, described PTO drive disk is arranged in bearing block by YRT bearing, and described PTO drive disk is by soft Property shaft coupling with output ring gear be connected.
Described planetary wheel carrier is by two wheel-type supports being connected as a single entity and one of them is near the wheel-type of outfan Support with outfan axle journal constitute, the two ends of described planet wheel spindle are arranged on two wheel-type by bearing On support, described input planet gear and output planetary gear are between two wheel-type supports；Described dynamic Power output panel is arranged on outfan axle journal by bearing.
Described YRT bearing is integrated with PTO drive disk, bearing block, by PTO drive disk external diameter On the annular boss that has, be arranged on three row rollers of annular boss three, and by bearing block and gland Press-fit composition.
Described flexible clutch is flexible sheet shaft coupling.
Described input ring gear is fixed with end cap near input side.
Compared to prior art, this utility model has the advantages that
1, by YRT bearing optimization being designed as integral structure, thus have more compact construction and Less volume, the most also ratio uses independent YRT bearing completed products to considerably reduce cost.Corpusculum Amass and can accomplish external diameter 77mm, thickness 44mm.
2, power shaft and output shaft are in same center of rotation, improve axially, radially bearing capacity, pass Torque delivery is big.
When 3, installing, power intake can be with motor coaxle direct connection, and only one of which shoulder is as benchmark, because of This is 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 scope reaches 500-40.
5, exporting power by flexible clutch, the operation that collides during using for robot can be played Buffering, cushioning effect, protection reductor, from rigid impact, extends the life-span, it is ensured that precision.
6, there is power-off and shut down auto-lock function.After power-off is shut down, when outfan applies moment of torsion, reducing gear Not rotating, band band-type brake motor therefore need not be selected as input power, not only reliability is high, reduces and makes With cost, and easy to maintenance.
