Abstract
The invention relates to a locking system of a self-elevating drilling platform, in particular to a worm gear reducer for a locking system of a self-elevating drilling platform. The worm gear reducer comprises a worm gear and a box, wherein the worm gear is arranged in the box; and a bearing liner is arranged between the lower portion of the worm gear and the bottom of the box. When the locking system is in a locking state, the bearing liner can serve as a pressure-bearing gasket. The circumstance that pressure on a portion between the worm gear and the bottom of the box is over high and unlocking of the locking system is affected is avoided. After the locking system is unlocked, the worm gear is driven to rotate via a worm, at the moment, the bearing liner on the bottom of the box not only can serve as the pressure-bearing gasket, but also can serve as a sliding bearing, the worm gear is prevented from being in direct contact with the box during rotation, and a worm gear and worm pair can run smoothly.
Description
Technical field
The present invention relates to self-elevating drilling platform fastening system, be specifically related to a kind of worm gear reducer for self-elevating drilling platform fastening system.
Background technique
Worm mechanism is a kind of mechanical transmission form of extensive use, is also the critical component of current ocean self-elevating drilling platform fastening system simultaneously.Be different from general worm gear, in the axis hole of this worm gear part, be provided with the motion thread of self-locking property, bear immense pressure under working state, far beyond the bearing capacity of standard rolling bearing.For ensureing that worm couple can operate smoothly, therefore need a kind of special bearing part.
Summary of the invention
For prior art Problems existing, provide a kind of worm gear reducer for self-elevating drilling platform fastening system that worm couple operates smoothly that can ensure.
The technical solution used in the present invention is:
For a worm gear reducer for self-elevating drilling platform fastening system, comprise worm gear and casing, described worm gear is arranged in described casing, between the below of described worm gear and the bottom of described casing, be provided with bearing shim.
As the preferred embodiments of the invention, also comprise carrying screw rod, be provided with the motion thread matched with described carrying screw rod in the axis hole of described worm gear, described carrying screw rod is arranged in the axis hole of described worm gear.
As the preferred embodiments of the invention, described motion thread is the motion thread with self-locking property.
As the preferred embodiments of the invention, also comprise the case lid be arranged on above described worm gear.
As the preferred embodiments of the invention, also comprise the worm screw with described worm gear transmission.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, when fastening system is for locking state, pressure is delivered to worm gear and casing by carrying screw rod, now worm gear is in static, immense pressure between worm gear and casing far exceeds the bearing capacity of general standard bearing, and under this state, bearing shim of the present invention can play the effect of a pressure-bearing pad.Avoid pressurized between worm gear and bottom half excessive and affect fastening system unblock.
2, after fastening system unlocks, worm gear is by worm screw driven rotary, and now the bearing shim of bottom half is except being a pressure-bearing pad, also plays the effect of a sliding bearing, avoids worm gear and directly contact with casing in rotation.Ensure that worm couple can operate smoothly.

Mark in figure: 1-worm gear reducer, 101-worm gear, 102-worm screw, 103-motion thread, 2-carries screw rod, 3-wedge-shaped blocks, 4-lifter rack, 5-locking block tooth bar, 6-casing, 7-bearing shim, 8-case lid.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention will be further described.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
embodiment 1
As shown in Figure 1, worm gear reducer 1, carrying screw rod 2 and wedge-shaped blocks 3 are critical components of self-elevating drilling platform fastening system, and these three parts lower bear huge pressure in working order, and locking block tooth bar 5 and lifter rack 4 are locked.Three arrows in Fig. 1 represent the immense pressure from multiple directions that these three parts bear.
Shown in composition graphs 2 and Fig. 3, arrange the motion thread 103 matched with carrying screw rod 2 of band self-locking property in the axis hole of worm gear 101, carrying screw rod 2 is arranged in the axis hole of described worm gear 101.Bearing shim 7 is provided with between worm gear 101 and the bottom of casing 6.
When fastening system is for locking state, pressure is delivered to worm gear 101 and casing 6 by carrying screw rod 2, now worm gear 101 is in static, immense pressure between worm gear 101 and casing 6 far exceeds the bearing capacity of general standard bearing, and the bearing shim 7 under this state only plays the effect of a pressure-bearing pad.
After fastening system unlocks, worm gear 101 is by worm screw 102 driven rotary, and the bearing shim 7 now bottom casing 6, except being a pressure-bearing pad, also plays the effect of a sliding bearing, avoids worm gear 101 and directly contacts with casing 6 in rotation.As shown in Figure 3, also comprise the case lid 8 be arranged on above described worm gear 101, also comprise the worm screw 102 with described worm gear transmission.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
