Abstract
The invention discloses a screw thread locking device without differentiating rotating directions, which includes a lock ring (5), a compression ring (3) and a bolt (4), wherein screw threads are arranged in the lock ring (5); screw threads reverse to the lock ring (5) are arranged in the compression ring (3); the lock ring (5) is connected with the compression ring (3) through a bolt (4); and a lock spacer (2) is arranged between the bolt (4) and the compression ring (3). The invention has the benefits that the problem that the screw thread locking device can be universally used due to the difference of the rotating direction is solved, and the locking device has a simple structure, and is convenient to realize and dismount. The invention plays a substantial function for solving the universal use problem of the screw thread locking device.
Description
Technical field
The present invention relates to a kind of screw-threaded coupling device, specifically is a kind of screw-threaded coupling device of not distinguishing rotation direction.
Background technique
Locking device is used for the moment of torsion of passing shaft to axle sleeve, uses screw-threaded coupling, needs to consider the rotation direction problem of axle.If do not consider that rotation direction then possibly cause locking device to come off.Cause axle sleeve can not follow axle rotation together, thereby cause mechanical seal not have seal action.This just needs a kind of locking device that need not distinguish rotation direction with regard to the ability transmitting torque.Thereby avoided owing to the inconsiderate seal failure that causes of rotation direction problem.
Summary of the invention
The purpose of this invention is to provide a kind of screw-threaded coupling device of not distinguishing rotation direction, be used for the transmission of mechanical seal moment of torsion, the screw thread on cooperation axle sleeve and the axle plays the effect of transmitting torque, reaches rotating ring and follows the axle purpose of rotation together.
Technological scheme of the present invention is achieved in that a kind of screw-threaded coupling device of not distinguishing rotation direction; Comprise locking ring (5), hold-down ring (3) and bolt (4); Locking ring has screw thread in (5); Have in the hold-down ring (3) and the reverse screw thread of locking ring (5), said locking ring (5) and hold-down ring (3) link through bolt (4).Establish locked spacer (2) between said bolt (4) and the hold-down ring (3).
The invention has the beneficial effects as follows: solved in the screw-threaded coupling device because rotation direction is different can not general locking device problem, and this locking device structure is simple, it is convenient to realize, is convenient to dismounting.The present invention has played substantial effect for the common question that solves screw-threaded coupling device.
Description of drawings
Fig. 1 is the partial sectional view of user mode of the present invention.
Fig. 2 is a locking device plan view of the present invention.
Among the figure: 1. spool; 2. locked spacer; 3. hold-down ring; 4. bolt; 5. locking ring; 6. axle sleeve.
Embodiment
Below in conjunction with specific embodiment the present invention is further explained.
A kind of screw-threaded coupling device of not distinguishing rotation direction comprises locking ring 5, hold-down ring 3 and bolt 4, in the locking ring 5 screw thread is arranged, and the screw thread reverse with locking ring 5 arranged in the hold-down ring 3, and said locking ring 5 links through bolt 4 with hold-down ring 3.Establish locked spacer 2 between said bolt 4 and the hold-down ring 3.Its method for using is: install on axle sleeve 6 to the axle 1; After the locking ring 5 of packing into, notice that locking ring end face and axle sleeve end face stay the 1.5-2mm distance; Dress hold-down ring 3 makes hold-down ring compress axle sleeve; The adjustment locking ring makes that through hole aligns on locking ring upper bolt hole and the hold-down ring, dress locked spacer 2 and bolt 4, and lock.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. screw-threaded coupling device of not distinguishing rotation direction; It is characterized in that; Comprise locking ring (5), hold-down ring (3) and bolt (4); Locking ring has screw thread in (5), has in the hold-down ring (3) and the reverse screw thread of locking ring (5), and said locking ring (5) and hold-down ring (3) link through bolt (4).
2. the screw-threaded coupling device of not distinguishing rotation direction according to claim 1 is characterized in that, establishes locked spacer (2) between said bolt (4) and the hold-down ring (3).
