The technological scheme that its technical problem that solves the utility model adopts is: a kind of vertical cycloid pinwheel reduction gear, comprise the speed reducer body, output shaft, cycloid wheel and center pivoted arm, described speed reducer body has support, pin wheel housing and electric machine joint, support and pin wheel housing, pin wheel housing and electric machine joint all connect by stay bolt, described output shaft connects by drive plate with cycloid wheel, offer the pin shaft hole that press-fits bearing pin on the drive plate, cycloid wheel offers endoporus, on the pivoted arm of described center cylindrical roller bearing is installed, the endoporus of cycloid wheel matches with cylindrical roller bearing, described speed reducer body is provided with oil pump, oil pump connects the oil transportation copper pipe, and the outlet port of oil transportation copper pipe is positioned at a high speed level bearing place.
Have band stop ring selfaligning roller bearing on the described output shaft, can bear large load and radial force, be with simultaneously stop ring that output shaft and support are reached the axially locating effect.
The output terminal of described speed reducer body also is provided with retaining ring and rotary dual-oil seal outward successively.Output terminal adopts the rotary oil seal sealing, retaining ring is installed on the output shaft is done the oil sealing home record.The retaining ring surface hardness is high, and is more wear-resisting, can directly change if any damage after long-term the use simultaneously, and need not change output shaft, saved maintenance cost.
The material of described speed reducer body is gray cast iron, and the material of described output shaft is carbon steel, material and precision have improved, then vibrate little, noise is little, long service life.
The beneficial effects of the utility model are: the utility model output shaft and cycloid wheel adopt drive plate bearing pin pattern joint transmission, and cycloid wheel adopts the axial float design, and output terminal adopts rotary dual-oil seal to add the retaining ring mode and seals, and changes convenient easy to maintenance; Speed reducer is lubricated to adopt outer circulation to force with spraying lubricated, radiating effect and high lubricating effect, and lubricants capacity is saved simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. output shaft, 2. cycloid wheel, 3. center pivoted arm, 4. support, 5. pin wheel housing, 6. electric machine joint, 7. bearing pin, 8. retaining ring, 9. rotary dual-oil seal, 10. oil pump, 11. oil transportation copper pipes.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Vertical cycloid pinwheel reduction gear as shown in Figure 1, comprise the speed reducer body, output shaft 1, cycloid wheel 2 and center pivoted arm 3, the speed reducer body has support 4, pin wheel housing 5 and electric machine joint 6, support 4 and pin wheel housing 5, pin wheel housing 5 and electric machine joint 6 all connect by stay bolt, output shaft 1 and cycloid wheel 2 connect by drive plate, offer the pin shaft hole that press-fits bearing pin 7 on the drive plate, cycloid wheel 2 offers endoporus, on the center pivoted arm 3 cylindrical roller bearing is installed, the endoporus of cycloid wheel 2 matches with cylindrical roller bearing, the speed reducer body is provided with oil pump 10, and oil pump 10 connects oil transportation copper pipe 11, and the outlet port of oil transportation copper pipe 11 is positioned at a high speed level bearing place.
Output shaft 1 adopts drive plate form transmitting torque with cycloid wheel 2, press-fits bearing pin 7 on the drive plate of output shaft 1 behind the tooling pin axis hole, on the center pivoted arm 3 cylindrical roller bearing is installed, and can bear large radial force and driven loads.
