Abstract
The utility model provides a special gear box of a concrete mixing truck with engagement of a plurality of teeth and two-level transmission. The special gear box comprises a machine base, an input shaft, a drum-shaped tooth coupling (7), an NGW (narrow gap welding) planetary transmission mechanism, a special coupling, a planetary wheel transmission mechanism, a drum-shaped tooth coupling (3), a center-aligning roller bearing and an output flange. The input shaft is connected with the drum-shaped tooth coupling (7), the drum-shaped tooth coupling (7) is connected with the NGW planetary transmission mechanism, the NGW planetary transmission mechanism is connected with the special coupling, the special coupling is connected with the planetary wheel transmission mechanism, the planetary wheel transmission mechanism is connected with the drum-shaped tooth coupling (3), the drum-shaped tooth coupling (3) is connected with the center-aligning roller bearing, and the center-aligning roller bearing is connected with the output flange. The special gear box has two structures: the NGW planetary transmission mechanism is used as an input end while the planetary wheel transmission mechanism is used as an output end in one structure, or the planetary wheel transmission mechanism is used as an input end while the NGW planetary transmission mechanism is used as an output end in the other structure. The special gear box of the concrete mixing truck has the advantages of short transmission chain, high transmission efficiency, multi-teeth engagement, large output torque and low requirements for machining accuracy, materials and thermal treatment.
Description
(1) technical field
The utility model relates to mechanical subject, is exactly a kind of concrete mixing and transporting car special gear box specifically.
(2) background technique
At present domestic widely used concrete mixing and transporting car gear-box all is external import (domestic still do not have this product), main brand has: German ZF:P3301, P4300, PLM7, PLM9, U.S. Sa Australia: TM51.2,61.2,71.2, Italy nation flies profit: 575L, 577L, 580L, Italy PMP:6SP, 7SP, Italy TOPUNION:P68, Daikin: DD33-MF, Japanese KYB:RC100, RC102 etc.The main structure form of the said goods is as follows: the two-stage Gear Planet Transmission; The two-stage planet adds the one-level driving of parallel axes; The third-level planetary transmission; One-level NW adds the one-level Gear Planet Transmission.Be characterized in: volume is little, output torque is big, and the accuracy of manufacturing of gear is required high (more than 5 class precisions), and material and heat treatment etc. require also very high, and domestic associated production producer prior art is difficult to realize.
(3) summary of the invention
The purpose of this utility model is to provide a kind of multiple tooth engagement, two-stage transmission, concrete mixing and transporting car special gear box that transmission efficiency is high.
The purpose of this utility model is achieved in that it is made up of support, input shaft, crowned teeth connection, NGW epicyclic transmission mechanism, special-purpose coupling, star wheels transport mechanism, crowned teeth connection, selfaligning roller bearing and output flange, input shaft connects crowned teeth and connects, crowned teeth connects and connects the NGW epicyclic transmission mechanism, the NGW epicyclic transmission mechanism connects special-purpose coupling, special-purpose coupling connects star wheels transport mechanism, star wheels transport mechanism connects the crowned teeth connection, crowned teeth connects the connection selfaligning roller bearing, and selfaligning roller bearing connects output flange.
Described concrete mixing and transporting car special gear box has two kinds of structural types: input stage is the NGW epicyclic transmission mechanism, and output stage is that star wheels transport mechanism or input stage are star wheels transport mechanism, and output stage is the NGW epicyclic transmission mechanism.
A kind of concrete mixing and transporting car special gear box of the utility model, it is that a kind of boundary dimension and imported product are in full accord, has the substitute products of independent intellectual property right brand new.Compare with existing imported product, its main feature is that Transmitted chains is short, transmission efficiency is high, multiple tooth engagement, output torque are big, and machining accuracy, material and heat treatment etc. require low relatively, and domestic existing processing technique can meet design requirement fully.
(4) description of drawings
Fig. 1 is the NGW Gear Planet Transmission for input stage of the present utility model, and output stage is the transmission principle figure of star-wheel transmission;
