Description

Retarder with the design of automobile axle active and passive gear accessory

One. technical field

The utility model relates to a kind of retarder, and especially a kind of retarder with automobile axle active and passive gear accessory design is suitable for using on the engineering goods of needs deceleration such as shredder.

Two. background technique

At present, the retarder of on the engineering goods that needs such as shredder slow down, using, especially in 50～150KW, the retarder used on the high-power ultra tiny pulverizing machine, all want the retarder of design specialized, because special-purpose retarder is little in batches, manufacture cost is high, only the cost price of separate unit retarder just reaches 1～20,000 yuan, and the retarder producer of specialty all is unwilling to practice midwifery, and just seems urgent unusually so seek a kind of shredder retarder that designs with universal accessories.Maximum both at home and abroad and the most universal enterprise should be an auto manufacturing, the ransaxle of automobile or tractor is a driving gear of power being passed to ransaxle by gearbox and transmission shaft, drive driven gear by driving gear, drive differential mechanism by driven gear again, rotate drive planetary pinion and differential gear by differential mechanism, differential gear drives the semiaxis on vehicle bridge both sides, tire on the drive wheels travels, have the advantages that the accessory amount is big, universal, price is low, but its power divides two-way output, is unsuitable for using on other engineering goods of needs deceleration such as shredder.

Three. summary of the invention

Task of the present utility model provides a kind of improved shredder retarder, and it can reduce production costs, and can guarantee the deceleration mechanical property of shredder again.

For finishing this task, the utility model carries out in the following way:

Retarder with the design of automobile axle active and passive gear accessory, it comprises: the driving gear that automobile axle is used, driven gear are formed, and it also comprises: driving gear housing, driven gear support, power input flange connector, bearing support, bearing cap, bearing, reducer shell, output shaft upper end cap, output shaft flange connector, output shaft, half of bearing cap, bonnet, means of deflation, packing ring, round nut lock washer, round nut, output shaft lower end cap are formed; Be vertically arranged with the output shaft by the pair of bearings carrying in driving gear housing and the reducer shell, the output shaft stage casing is with driven gear support and driven gear, and epimere is by the sealing of output shaft upper end cap, and the epimere termination is with the output shaft flange connector; Reducer shell one side is horizontally arranged with by the driving gear of loading ability of bearing and power input flange connector thereof, and opposite side is sealed by bonnet, and the bottom is by the output shaft lower end cap; After be covered with a means of deflation, press to regulate in the reducer shell; Described driven gear support respectively is provided with a packing ring, round nut lock washer, round nut assembly up and down, to regulate the backlash of driven gear and driving gear engagement.

The utility model is because of only needing design driven gear support replace differential assembly, and the driving gear, the driven gear that still adopt automobile axle to use are so the accessory amount is big, universal, price is low; Simultaneously because the watt level of other engineering goods that can slow down according to needs such as shredders and the height of output speed are selected the modulus and the gear ratio of different gears, so can satisfy the structural strength of retarder and the requirement of rigidity and output speed.
