Problems solved by technology

[0011] The prior art involved in the technical field of the present invention——hydraulic coupling forward gear box, although it solves the problem of low transmission efficiency compared with hydraulic torque converter, it does not have torque conversion function and is not suitable for Oil drilling rigs operate in areas with complex geological conditions, frequent tripping conditions, and drilling depths exceeding 5,000 meters; in addition, it has a large penetration number. box and parallel car chain box, the "penetrating" hydraulic coupling is applied to the diesel engine, causing black smoke from the diesel engine, or even stalling, deteriorating combustion conditions, and reducing its service life

Embodiment Construction

[0022] The present invention is a gear box for a hydraulic torque converter coupling, and its structural diagram is as attached figure 1 As shown, it is composed of a hydraulic torque converter coupling in the input part and a two-stage coaxial gear reducer in the output part. The input part is a three-blade hydraulic torque converter coupling composed of a short pump wheel 6 with straight blades, a turbine 5 with straight blades and a guide wheel 7 with twisted blades. It has no auxiliary chamber and its main zero The components are: input flange 1, input shaft 2, pump wheel cover 3, pump wheel 6, turbine 5, guide wheel 7 and turbine shaft 4, etc. The output part consists of the input shaft (that is, the turbine shaft of the hydraulic torque converter coupling) 4, the driving gear 9 and the driven gear 8 of the first-stage gear pair, the intermediate shaft 11, the driving gear 10 and the driven gear of the second-stage gear pair Two-stage coaxial gear reducer composed of gea...

Abstract

The invention discloses an ahead running reduction box with a hydraulic torque-converting coupler. The ahead running reduction box with the hydraulic torque-converting coupler is a transmission device arranged between a diesel engine and a compound chain box in a mechanical transmission oil drilling rig, and comprises the hydraulic torque-converting coupler used as an input part and a two-stage coaxial gear reducer used as an output part, wherein the input part is the hydraulic torque-converting coupler without an auxiliary cavity, and is installed in the same box body together with the two-stage coaxial gear reducer used as the output part; a turbine shaft and the input shaft of the two-stage coaxial gear reducer have the same radical axis; and the power oil in a working cavity and the lubricating oil in the two-stage coaxial gear reducer are the same oil product, and share an oil circulation system with an oil pump and a cooler. The transmission device has the advantages that the transmission efficiency is high, and the fuel oil consumption can be greatly reduced; a torque converting function is achieved, thus the well-drilling efficacy is greatly improved; and the permeability number is smaller, thus the combustion conditions of the diesel engine can be improved, and the service life is improved.

Description

technical field [0001] The invention relates to a transmission device between a diesel engine and a parallel chain box in a mechanical transmission oil drilling rig. Background technique [0002] 1. Background technology in the technical field related to the present invention [0003] In the mechanical transmission oil drilling rig, the transmission device between the diesel engine and the parallel chain box has the following two types so far: [0004] First. Hydraulic torque converter (see SY / T5141-2002 standard) [0005] It is mainly composed of a rotating pump wheel and a turbine and a fixed guide wheel, a total of three impellers, all of which are twisted blades. Its main performance characteristics are: it has the function of variable torque (that is, continuously variable speed), and is suitable for drilling operations in various areas (including complex geological conditions, frequent tripping, and drilling depths exceeding 5,000 meters). Its disadvantage is that t...
