A motor is arranged at the top end of a caliber outer shell, a rotating shaft is arranged at one end of the motor, a sun gear is arranged on the rotating shaft, a spiral piece opening is formed in the lower portion of an inner cavity of the caliber outer shell, the spiral piece opening is fixed through a nut, a spiral piece penetrates through the spiral piece opening and is then hinged to a planet gear through a connecting key, the planet gear is connected with the sun gear through a planet supporting piece in a butt joint mode, a general-purpose piece is arranged at the lower end of the spiral piece, and the general-purpose piece is sealed by a sealing piece and fixed on the caliber outer shell.
Description
Technical field
The utility model relates to a kind of brake nut helical member mechanism, and particularly the electric universal brake nut of a kind of hydraulic pressure helical member mechanism belongs to the break technical field.
Background technique
The electric universal brake nut of hydraulic pressure helical member mechanism is the important accessory structure of break, in the electric universal brake nut of present hydraulic pressure helical member mechanism, all be to adopt the mode of structure of planetary pinion and motor to assemble, because the revolution space of motor is little, the surface of contact of planetary pinion and motor obviously reduces, easily cause nut and helical member mechanism to damage, also have the defective of its mechanism structure complexity, inconvenient maintenance.
Summary of the invention
The purpose of this utility model is: a kind of compact structure, the general electric universal brake nut of a kind of hydraulic pressure helical member mechanism effective, easy to maintenance are provided, overcome the existing defects of the electric universal brake nut of existing hydraulic pressure helical member mechanism.
The technological scheme that its technical problem that solves the utility model adopts is: the electric universal brake nut of a kind of hydraulic pressure helical member mechanism, it is comprised of clamp shell, motor, rotating shaft, central gear, planet supporter, planetary pinion, connecting key, helical member mouth, nut, helical member, Sealing, general part, described nut helical member mechanism is provided with a motor on the top of clamp shell, end at motor is equipped with rotating shaft, and a central gear is installed in the rotating shaft; In the bottom of clamp shell inner cavity one helical member mouth is installed, the helical member mouth is fixed by nut, and helical member is hinged by connecting key and planetary pinion after passing the helical member mouth, and planetary pinion connects by planet supporter and central gear; Be provided with a general part in the lower end of helical member, general part by Sealing sealing and be fixed on the clamp shell above.
The beneficial effects of the utility model: because the utility model has adopted the motor driving rotating shaft, rotating shaft drives central gear, mechanism's mode that central gear connects helical member mouth mounting nuts and helical member and seals by Sealing by planetary pinion, make whole brake nut helical member mechanism have compact structure, general effective, advantage easy to maintenance, effectively overcome the existing revolution space owing to motor of the electric universal brake nut of existing hydraulic pressure helical member mechanism little, the surface of contact of planetary pinion and motor obviously reduces, the defective that easily causes nut and helical member mechanism to damage.
