Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The core of the invention is to provide a TBM main drive planetary reducer, the brake device of which is convenient for maintenance and operation. Another core of the present invention is to provide a TBM comprising the above TBM main drive planetary reducer, the braking device of the reducer is easy to maintain and operate.

[0029] It should be noted that when an element is referred to as "fixing" another element, it may be directly on the other eleme...

Abstract

The invention discloses a TBM main drive planetary reducer and a TBM. The reducer includes a braking device, a motor, and a reducer main body connected to the output end of the motor. The braking device is placed outside the main body of the reducer and the motor, specifically including a housing outside the main body of the reducer and the motor. The housing is provided with a hydraulic oil port, and the housing is equipped with a mandrel, a dynamic friction plate, a static friction plate and an elastic The mandrel is rotatably connected to the housing, and the mandrel is fixedly connected to the input shaft of the motor; the elastic member is placed between the moving friction plate and the housing, so that the moving friction plate is pressed axially against the static friction plate by the reset force of the elastic member; The hydraulic oil port is connected to the hydraulic system, and the hydraulic system supplies hydraulic oil to the brake device through the hydraulic oil port, so as to drive the dynamic friction plate to separate from the static friction plate through the hydraulic oil. Since the braking device is placed outside the main body of the speed reducer, no braking device is provided in the main body of the speed reducer, and the operating space outside the main body of the speed reducer is large, so that the braking device is convenient for maintenance and operation.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a TBM main drive planetary reducer and a TBM. Background technique [0002] For super underground engineering equipment, especially TBM (Tunnel Boring Machine) hard rock tunnel boring machine main drive planetary reducer, if there is no braking device (at this time the reducer gradually stops with its inertia) or the braking device If the braking time is too long, it will pose a great challenge to the safety of personnel during the tool change process of the TBM hard rock tunnel boring machine; Fatigue damage to internal structures such as the drive system and the transmission system directly affects the equipment safety and service life of the TBM hard rock tunnel boring machine. Therefore, during the operation of the TBM hard rock tunnel boring machine, its main drive should use a reducer with a braking device for the main drive. [0003] At present, the brake de...
