Abstract
The utility model relates to a synchronous mechanical cylinder which comprises an input shaft, a gear box body, a driving bevel gear, a driven bevel gear, first pair bearings, a ball screw, a leadscrew nut, a connecting bolt, an outer sleeve, an inner sleeve, a cylinder end, a slip ring, second pair bearings, a trunnion, a radial spherical plain bearing, a dust cover, stoppers and a connecting ring, wherein the input shaft penetrates through the gear box body; the driving bevel gear is connected with the input shaft through a spline; the driven bevel gear is connected with a spline on the ball screw; two ends of the ball screw are respectively supported by the first pair bearings and the second pair bearings; the leadscrew nut is connected with the inner sleeve through the connecting bolt; a gear box is connected with an outer thimble through the connecting ring the stops are arranged between the first pair bearings and the leadscrew nut; and the slip ring is arranged at the tip of the second pair bearing of the ball screw. The synchronous mechanical cylinder provided by the utility model is used in pair, thereby having high synchronous precision, high transmission speed, lower driving torque, larger thrust, smaller structure size and high safety and reliability.
Description
Technical field
The utility model belongs to lifting, push-and-pull machinery, especially belongs to the synchronization mechanism cylinder, has the motor function of hydraulic ram, and general paired use is high synchronization accuracy effectively, is used for medium and heavy lifting cylinder and replaces hydraulic ram.
Background technology
At present, the lifting cylinder is that a fixed load is realized the device of up-down, is divided into cylinder, oil cylinder, Mechanical cylinder, light-duty cylinder, heavy cylinder etc. by different media or load; The design belongs to Mechanical cylinder, and the domestic blank that also is in basically of the medium and heavy Mechanical cylinder of precise synchronization is in medium and heavy lifting cylinder; What mainly adopt is hydraulic ram; But hydraulic ram in use, problems such as hydraulic oil seepage often occur, (like metallurgical system) work unreliable easy generation fire etc. in high-temperature work environment; This Mechanical cylinder uses in pairs has the higher synchronous precision, speed of transmission is fast, drive power source moment is less, and the bigger driving of thrust is flexible, scantling of structure is less, and safe reliability is high.
Summary of the invention
The purpose of the utility model provides a kind of medium and heavy synchronization mechanism cylinder, and its structure comprises input shaft, denticle casing, drive bevel gear, driven wheel of differential, bearing, ball-screw, feed screw nut, coupling bush, outer sleeve, inner sleeve, cylinder head, slip ring, bearing, gudgeon, plain radial bearing, dust boot, block, coupling link.Input shaft passes gear case, drive bevel gear is connected with input shaft with spline; Driven wheel of differential is connected with spline on the ball-screw; With bolted connection, gear case is connected with outer sleeve through coupling link, between first pair of bearing and feed screw nut, is provided with block with bearing supporting, feed screw nut and inner sleeve at the ball-screw two ends; Second pair of bearing of ball-screw is provided with slip ring; Claim gudgeon again at the output adapter shaft, in gudgeon, set up plain radial bearing, the inner sleeve of second pair of bearing one end is provided with dust boot.
Adopt the beneficial effect of present technique scheme: use synchronization accuracy high in pairs, speed of transmission is fast, and drive torque is less, and thrust is bigger, and scantling of structure is less, and safe reliability is high.
