Abstract

The utility model provides a separable gear coupler, relates to couplers of heavy-duty machinery, and solves the problems of highly cumbersome operation when the conventional gear coupler is used for separating two transmission shafts. The separable gear coupler comprises two inner sleeves and two outer sleeves, wherein the inner sleeves with external teeth are connected with a driving shaft and a driven shaft respectively; and the outer sleeves, which are provided with internal teeth and flanges, are meshed with the two inner sleeves respectively. The separable gear coupler is characterized in that two isolation rings can be mounted between two junction surfaces of the two outer sleeves respectively; positioning spigots are arranged in the inner holes of the isolation rings, and are matched with positioning spigots on the inner sleeves; and the isolation rings and the flanges of the outer sleeves are fixed through connecting bolt groups. The separable gear coupler is suitable for various heavy-duty machinery equipment with low rotational speeds, large rotating torques, as well as the requirement that the rotational speeds and the rotational angles of the driving shaft and the driven shaft are the same.

Description

A kind of releasable gear coupling

Technical field

The utility model relates to heavy duty equipment, particularly the gear coupling of heavy machinery.

Background technique

At present, existing gear coupling can only be used for coupling together two transmission shafts, realizes the transmission of motion and torque.In the time need separating two transmission shafts for a certain reason, need move the machinery of a side earlier, widen two gaps between the transmission shaft, pull down the outer sleeve of both sides half-coupling, could be separately two axles.Like this, not only waste time and energy, very loaded down with trivial details, sometimes even be difficult to realize.Usually, realize that frequent the combination with the occasion of separating is to adopt clutch between two axles.Adopt clutch to exist following deficiency: the one, because structure and size, transmitting torque is restricted; The 2nd, opening, skidding in the braking process, make the driving shaft motion not pass to driven shaft fully, cause the angle of transient speed and rotation of two axles unequal; The 3rd, need certain engaging power or mechanial control device, cost is higher.Therefore, general clutch is not suitable for the occasion that torque is very big, require to have between driving shaft and the driven shaft same rotational speed and corner, seldom combine or separate.

Summary of the invention

The purpose of the utility model is to overcome the shortcoming of existing technology, and a kind of releasable gear coupling is provided, and solves existing gear coupling when needs separate two transmission shafts, operates very loaded down with trivial details problem.

The task of the utility model is to adopt following measure to realize:

A kind of releasable gear coupling; Comprise: two inner sleeves that have external tooth that are connected respectively with driving shaft and driven shaft; Two outer sleeves that have internal tooth and flange that mesh respectively with two said inner sleeves; It is characterized in that: said coupling can be installed two isolating rings respectively between the junction surface of two said outer sleeves, the endoporus of said isolating ring has positioning spigot; Cooperatively interact with the positioning spigot on the said inner sleeve, the flange of said isolating ring and said outer sleeve is fixed with the connecting bolt group.

Said isolating ring is split type, is that subdivision is two semi-rings between wherein, and available bolt links together two semi-rings.

Separating of coupling: push two outer sleeves open, be contained in barrier cuffs on the inner sleeve, fix with connecting bolt group and outer sleeve, the gear between the inner and outer sleeves is in disengaged condition at this moment.The combination of coupling: take out isolating ring, link together two outer sleeves with connecting bolt, the gear between the inner and outer sleeves is in engagement at this moment.

The utility model compared with prior art not only can transmit very big torque, and guaranteeing has same rotational speed and corner between driving shaft and the driven shaft, and because two isolating rings are set between two outer sleeves, can realize separating of gear coupling.The utility model is applicable to the various heavy duty equipments that rotating speed is not high, torque is very big, require to have between driving shaft and the driven shaft same rotational speed and corner.

The utility model is further described through embodiment below in conjunction with accompanying drawing.

Concrete mode of execution

Like Fig. 1, shown in 2; A kind of releasable gear coupling; Comprise: with two inner sleeves 3 that have external tooth that driving shaft 1 and driven shaft 2 are connected respectively, with two outer sleeves 4 that have internal tooth and flange that two said inner sleeves 3 mesh respectively, it is characterized in that: said coupling can be between the junction surface of two said outer sleeves 4; Two isolating rings 5 are installed respectively; The endoporus of said isolating ring 5 has positioning spigot, cooperatively interacts with positioning spigot on the said inner sleeve 3, and said isolating ring 5 is fixing with connecting bolt group 6 with the flange of said outer sleeve 4.

As shown in Figure 3, said isolating ring 5 is split type, is that subdivision is two semi-rings between wherein, and available bolt 7 links together two semi-rings.

As illustrated in fig. 1 and 2, in the time of need separating two axles, push two outer sleeves 4 open, be sleeved on isolating ring 5 on the inner sleeve 3, fixing with outer sleeve 4 with connecting bolt group 6 isolating ring 5.

As shown in Figure 4, in the time of need combining two axles, pull down isolating ring 5, be close together two outer sleeves 4, link together two outer sleeves 4 with connecting bolt group 6.
