Transmission box of road roller

Abstract

The invention relates to the technical field of transmission boxes for road rollers and discloses a transmission box of a road roller, which comprises a low-speed transmission mechanism for a forward gear, a travelling high-speed transmission mechanism, a transmission mechanism for a reverse gear, a chain wheel output power transmission mechanism, a forward and reverse gear remote shift mechanism and a high-low speed remote gear shift mechanism, wherein the high-low speed remote gear shift mechanism is used for shifting the low-speed transmission and high-speed transmission of the forward gear; the forward and reverse gear remote shift mechanism is used for shifting the forward gear and reverse gear; and the low-speed transmission mechanism for the forward gear, the travelling high-speed transmission mechanism and the transmission mechanism for the reverse gear are connected with the steel wheels of the road roller by the chain wheel output power transmission mechanism. The transmission box for the road roller is reasonable in design, simple in structure, easy to machine, low in part fault rate and maintenance rate and has a high promotion and application value.

Description

[0001] technical field [0002] The invention relates to the technical field of road roller gearboxes, in particular to a road roller gearbox in the construction industry. Background technique [0003] At present, during the operation of the existing road roller gearbox, the gears are fragile, the failure rate is high, and the production cost is high, which brings many problems to the construction and after-sales service. The main disadvantages such as the existence of the original gearbox: [0004] 1. The structure is complex and the structure design is unreasonable; [0005] 2. The gear bearing capacity is low and the teeth are easy to break; [0006] 3. The power output shaft is prone to fracture due to the structure of the support frame; [0007] 4. There are many links in the operating system, and the technical requirements for adjustment are high. [0008] 5. The failure rate is high, which directly affects the productivity of the equipment; [0009] 6. The manufa...
