Abstract
The utility model discloses a kind of novel large speed ratio speed reducer assembly, include speed reducer housing, the main gearbox assembly, the differential assembly that are in transmission connection are installed in speed reducer housing, in speed reducer housing, driving shaft is installed, the end of driving shaft is provided with drive bevel gear, being meshed with drive bevel gear by dynamic bevel gear of main gearbox assembly, the utility model novel structure, compact, maximum drawbar pull can reach 30 tons, whole bridge reduction speed ratio is 8.17 can be loaded on general small volume tractor, safety, reliable.This product by experiment at present, obtains the accreditation of client and filled up a domestic blank in this field.
Description
Technical field
The utility model relates to big retarding than in the industrial vehicle of speed ratio and machinery, is especially useful in the speed reducer assembly in the special dimensions such as the ransaxle of the demand weight tractions such as airport, harbour, large ship.
Background technique
Main reducing gear is the important component part of industrial vehicle, be positioned at the end of vehicle drive system, also be the important component part of ransaxle, its fundamental function be engine torque that universal driving device is transmitted by main reducing gear, realize reducing rotating speed, increasing torque; The direction of transfer of torque is changed by taper gear pair.
The velocity ratio of general single reduction final drive is between 3.5-6.7, and too large velocity ratio will make the oversize of driven wheel of differential, affects the ground Clearance of driving axle housing lower end.Ground Clearance is less, and automobile passability is poorer.The main reducing gear which also limits large speed ratio cannot be installed on the vehicle of some dillies or compact structure.Therefore, this makes some narrow space, and the special of circumstance complication cannot use large-tonnage pulling equipment, constrains the development in this field.
Model utility content
The purpose of this utility model is to provide a kind of novel large speed ratio speed reducer assembly, this main reducing gear is single reduction gear, reduction speed ratio is 8.17, and with parking braking system, retarder maximum outside diameter is only Φ 370, this retarder is loaded on general 15 tons of tractors and also can ensures clearance, ensure the passing ability of vehicle.
The technical solution of the utility model is as follows:
A kind of novel large speed ratio speed reducer assembly, include speed reducer housing, the main gearbox assembly, the differential assembly that are in transmission connection are installed in speed reducer housing, in speed reducer housing, driving shaft is installed, the end of driving shaft is provided with drive bevel gear, being meshed with drive bevel gear by dynamic bevel gear of main gearbox assembly, passive caging bolt is equipped with by pressure outside dynamic bevel gear, driving shaft outer end is installed in speed reducer housing by bearing support, driving shaft the inner is installed in speed reducer housing by main tooth guide bearing, and bearing support is fixed by bearing block bolt.
The also larger design of the larger driven gear of reduction speed ratio broken by the utility model main reducing gear, achieves compact car and can use large speed ratio single reduction gear, and by the accreditation on probation of client, filled up the blank of China in this field.This drive axle structure is novel, compact, and maximum drawbar pull can reach 30 tons, and whole bridge reduction speed ratio is 8.17 can be loaded on general small volume tractor, safety, reliable.This product by experiment at present, obtains the accreditation of client and filled up a domestic blank in this field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See accompanying drawing, a kind of novel large speed ratio speed reducer assembly, include speed reducer housing 1, the main gearbox assembly 2 be in transmission connection is installed in speed reducer housing 1, differential assembly 3, driving shaft 4 is installed in speed reducer housing 1, the end of driving shaft 4 is provided with drive bevel gear 5, being meshed with drive bevel gear 5 by dynamic bevel gear 6 of main gearbox assembly, passive caging bolt 7 is equipped with by the outer side pressure of dynamic bevel gear 6, driving shaft 4 outer end is installed in speed reducer housing 1 by bearing support 8, driving shaft 4 the inner is installed in speed reducer housing 1 by main tooth guide bearing 9, bearing support 8 is fixed by bearing block bolt 10.
This master subtracts primarily of reducing gearbox assembly, differential assembly and main cingulum brake assembly three parts composition.The engine torque transmitted from universal driving device is transferred to differential assembly by driving tooth wheel belt parking braking assembly assembly by main reducing gear, realized reducing rotating speed, increasing torque to motor by the reduction speed ratio of tooth 8.17 by main, thus make car load obtain larger tractive force.Because this main reducing gear reduction speed ratio is larger, the more conventional retarder of the same type of engine input torque is much higher, therefore when designing, emphasis increases the casting strength supporting and slow down, and increases more stiffening rib and carrys out proof strength and in the intensity ensureing to strengthen the foundry goods such as differential carrier, bearing support, reducer shell to greatest extent under the prerequisite of fit up gap to ensure that this speed reducer assembly supports larger reduction speed ratio.Therefore, this main reducing gear is particularly useful for tractor and uses, and volume is little, and speed ratio is high, and attainable tractive force is large.
