Abstract

The utility model relates to a friction lining limit moment coupling. A lining is fixed on a second half coupling by a set screw. A sealing ring is arranged in the inner hole of the second half coupling which is sleeved on a reduction box shaft. A transmission wheel is fixed at the top end of the reduction box shaft. An upper pressure plate, a lower pressure plate, a driving friction lining and a driven friction lining are arranged between the second half coupling and the transmission wheel. A brake wheel is fixedly connected with the second half coupling through a bolt. A first half coupling is fixedly connected with a motor through a key and a nut. A cushion ring, a check ring and a pin are fixedly connected with the first half coupling through the nut. A spring seat and a spring are fixed on the first half coupling through a bolt and the nut. The utility model greatly improves the rotation stability of a crane. Because an oiled friction lining transmission manner is adopted, the service life of the coupling is prolonged and then the safe production performance of the whole crane is ensured.

Description

Frictional plate type limit torque coupling

Technical field

The utility model relates to a kind of frictional plate type limit torque coupling, specifically is used for connecting of rotary mechanism of crane motor and speed reducer, belongs to the machenical coupling technical field.

Background technique

In the hoist of various band rotating machinery, the motor in the rotating machinery connects the various coupling of usefulness with speed reducer, exist a lot of deficiencys at present.As easy damage, maintenance difficulty, installation precision requires high, and noise is big, and stability was bad etc. when hoist turned to, and greatly reduced hoist work efficient.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of stability can improve crane rotation greatly the time, the working life of shaft coupling can be prolonged, thereby the frictional plate type limit torque coupling of whole crane safety production performance can be guaranteed.

The technological scheme that provides according to the utility model, frictional plate type limit torque coupling, comprise lining, second half-coupling, from movable friction plate, active friction plate, platen up and down, Brake drum, buffer ring, back-up ring, pin, first half-coupling, spring seat, spring, drive wheel and bolt, lining is fixed on second half-coupling with Cock screw, install seal ring at the second half-coupling endoporus, second half-coupling is enclosed within on the deceleration arbor, drive wheel is fixed on the reducer shaft top, platen up and down, active friction plate, second half-coupling is installed in the middle of second half-coupling and the drive wheel, Brake drum is fixed with the bolt and second half-coupling, with the first half-coupling key, nut and motor are fixed, with buffer ring, back-up ring, pin is fixed spring seat with the nut and first half-coupling, spring is fixed on first half-coupling with bolt and nut.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Because this device has passed through series of steps such as resilient connection and the transmission of friction disk type secondary and has finished transmission to speed reducer, stability when having improved crane rotation greatly, owing to adopted the immersion oil friction plate kind of drive, thereby prolonged the working life of shaft coupling, and then guaranteed the safety in production performance of whole hoist.

Fig. 1 is the utility model structural representation.

Embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1, frictional plate type limit torque coupling described in the utility model comprises: lining 1, second half-coupling 2, from movable friction plate 3, active friction plate 4, platen 5, Brake drum 6, buffer ring 7, back-up ring 8, pin 9, first half-coupling 10, spring seat 11, spring 12, drive wheel 13 and bolt 14 etc. up and down.

The utility model is fixed on lining 1 usefulness Cock screw on second half-coupling 2, install seal ring at second half-coupling, 2 endoporus, second half-coupling 2 is enclosed within on the deceleration arbor, drive wheel 13 is fixed on the reducer shaft top, to platen 5 up and down, active friction plate 4, it is middle with drive wheel 13 to be installed in second half-coupling 2 from movable friction plate 3, the Brake drum 6 usefulness bolts and second half-coupling 2 are fixing, first half-coupling 10 is used key, nut and motor are fixed, with buffer ring 7, back-up ring 8, the pin 9 usefulness nuts and first half-coupling 10 are fixing, spring seat 11, spring 12 usefulness bolt and nuts are fixed on first half-coupling 10, spring pressure is transferred to required moment, inject lubricant oil, make coupling energy proper functioning, friction plate can play a role when moment was big.Prevent that lubricant oil from overflowing from the coupling endoporus, friction plate is immersed in the oil work, thereby reduced the degree of wear of friction plate.
