Embodiment
According to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation below.
Embodiment:
With reference to Fig. 1, Fig. 2, have the walking driving mechanism of special-purpose driving speed reducer amphibian digging machine, comprise oil hydraulic motor, take-off (propeller) shaft, driving speed reducer, sprocket wheel, crawler belt; Said driving speed reducer 1 comprises housing 5, motor bearing 6, third-level planetary frame 2, secondary external toothing 10, adds pouring orifice 3 and discharging hydraulic fluid port 4; Improvement is: the front end of the third-level planetary frame 2 of driving speed reducer 1 is provided with end cap flange 9; One side end face flange of end cap flange 9 is connected with bolt on the exterior edge face of secondary external toothing 10, and the opposite side end face flange of end cap flange 9 connects sprocket wheel 16 and is connected take-off (propeller) shaft 11 through center hole; On the said housing 5, be provided with O RunddichtringO 7 with the connection mouth inwall place of motor bearing 6.
The said pouring orifice 3 that adds is positioned at housing 5 radially on the outer wall of a side, adds in the pouring orifice 3 to be provided with screw plug; Said discharging hydraulic fluid port 4 is positioned on housing 5 and the outer wall that adds 3 one-tenth 90 ° of pouring orifices, is provided with screw plug in the discharging hydraulic fluid port 4.
On motor bearing 6, third-level planetary frame 2 and secondary external toothing 10 engagement driving constitute three grades of NGW speed reducer to housing 5 through Bearing Installation, seal through floating sealing ring 8 and seal ring 7 between housing 5 and the motor bearing 6.
With reference to Fig. 3, Fig. 5; The end cap 12 of prior art products is improved to end cap flange 9; Make the utility model not only sprocket wheel 16 can be installed at housing 5 places; And another sprocket wheel 16 and transmission shaft 11 transmitting torque (see figure 4)s can directly be installed at end cap flange 9 places, thereby make travel driving unit simple and reliable for structure, easy for installation.Prior art products can only be installed sprocket wheel 16 and take-off (propeller) shaft transmitting torque, take-off (propeller) shaft complex structure, processing difficulties at existing reducer shell 13 places.Because structural restriction, through hole is changed system in the original thread hole that also needs will have now on the reducer shell 13, and bolt connects from the negative, inconvenient installation.And the existing filler 14 and the existing floss hole 15 of prior art products is positioned at the end face of end cap 12, need remove take-off (propeller) shaft when filling and discharging gear oil, and be very loaded down with trivial details.The pouring orifice 3 that adds of the utility model designs on housing with discharging hydraulic fluid port 4; The screw plug that only need turn on filling and discharging hydraulic fluid port when filling and discharging gear oil gets final product; And the discharging hydraulic fluid port is in 4 speed reducer lowest parts; Can change the impurity of speed reducer internal gear oil and deposition fully, solve the problem of maintenance difficulty effectively, prolong working life.
Land and water excavator groundwork environment is marsh wetland and shallow water area, accumulates impurity such as mud between motor bearing 6 and the housing 5 easily, and the mud that particularly contains subparticle flows into its wearing and tearing of junction plane aggravation of floating sealing ring 8; For this reason; In floating sealing ring 8 outside design and installation O RunddichtringOs 7 (see figure 6)s, form a sealing configuration, prevent that impurity such as outside mud, mud from getting into; Improve the working condition of floating sealing ring, improve the working life of floating sealing ring.
Compartment crawler belt and roller chain structure have been adopted owing to the special working condition of land and water excavator with for adapting to this situation, to making running resistance very large more than common excavator.And the land and water excavator is operated in marsh wetland and shallow water area, causes the difficulty of maintenance.For this reason,, optimize gear parameter and third-level planetary frame and all adopt better rigidity double-walled integral planet carrier, improved bearing capacity, make the special-purpose driving speed reducer of amphibian digging machine can transmit bigger moment of torsion, higher reliability through design improvement.
