Abstract

The utility model relates to a controllable wedge retainer for the reducer shaft. The outer end of the pork in the controller of this retainer is drawn out to be connected with an active linkage rod which is connected with a magnetic case or a motor, pneumatic, hydraulic pushing rod and also with the power source of the main motor. The rolling bearing and the oil seal are mounted in the inner ring on the retaining parts which are sealed with the sealing cap. A plurality of special-shape pieces and its blocking pin and locating pin relative to them is placed between the external left ring and the internal right ring in the special-shape piece device. The left and right rotating springs respectively installed on the two ends of the special-shape piece. The anti-rotating arm utilities a separated structure, which is linked with the retaining parts by means of the anti-rotating shaft pin and the screw. When the retainer happens the fault, the anti-rotating pin shaft can be removed quickly as its main motor can not stop running or needs to run conversely according to the requirement of the conveyer. The main motor can drive the retaining parts to work positively and reversely; under different conditions, the non-contacting or contacting run is obtained to prevent the main motor running reversely The retainer is applied to the installation for use on the high speed rotating shaft with the speed of 0 -1500 r/min and the slow speed rotating shaft with the speed of 0-400 r / min.

The outer ring inwall of described check parts is provided with the step surface of two symmetries, and two fixing shelves rings are bound up on two step surfaces by screw, are linked with the front and back ends lid on the sidewall of outer ring, offers a shift fork rotation slot on the end face of arbitrary end of forward and backward end cap.

The left and right outer shroud of described special-shaped block assembly and left and right in the raceway that forms of the ring inner ring that is arranged on the check parts and outer ring, and by the backing pin on the left and right outer shroud prolong and two fixedly baffle ring connect firmly; Also be equipped with between the ring in left and right and the number corresponding backing pin of special-shaped piece and locating stud, and the corresponding collar extension by collar extension and left and right outer shroud is an one with link joint radially axially.

Described backing pin and locating stud are evenly distributed on left and right outer shroud and the left and right interior ring circumference separately.

Described shift fork link joint left and right outer shroud and left and right in the ring arbitrary end, the inner prong of shift fork be installed in the ring arbitrary locating stud on, this locating stud end is long slightly, the supporting point of shift fork is by screw and corresponding outer shroud link joint.

The positive beneficial effect that the utility model had:

1. anti-pivoted arm is for dividing body structure, when non-return device breaks down, when main frame temporarily can't stop transport or keep in repair conveying equipment and needs the main frame reversing, can pull down the anti-rotation bearing pin fast, and main frame can drive the positive and negative operation of check parts;

2. the backing pin of special-shaped block assembly by some on the left and right outer shroud prolong with two fixedly baffle ring connect firmly, two fixing shelves encircle by being bolted on outer ring inwall two step surfaces, special-shaped block assembly can not rotate with inner ring, can not produce wearing and tearing;

3. left and right outer shroud and left and right in backing pin and locating stud on the ring all be evenly distributed on same circumference, be convenient to process and with the assembling of special-shaped piece;

4. break down or during orderly closedown, controller cuts off the power supply thereupon when main frame, left and right in shift fork and special-shaped piece on the ring under the promotion of torsion spring, set back, special-shaped piece contact with the inside and outside circle of check parts, realizes that check function prevention main frame reverses;

5. break down can not use the time when controller, main frame does not need the shutdown of cutting off the power supply immediately, can move with remaining valid, and this moment, non-return device was realized the contact-type operation, and the check function of non-return device can not lose efficacy;

6. when maintenance main frame need reverse the time, the reversing of also can directly switching on, controller is connected thereupon, and the inside and outside circle of special-shaped piece and check parts disengages at this moment, and its inner ring can free forward and backward, keeps in repair very convenient;

7. the employing thin oil lubricant guarantees to realize contactless and contact-type operation under different use condition, realizes anti-main frame reversing, and is safe and reliable to operation, the working life that can improve non-return device; Be suitable on the lower velocity shaft of the high speed shaft of 0-1500r/min rotating speed and 0-400r/min rotating speed, installing and using.
