Technical Field

[0001] The present application relates to the technical field of gear box covers, and in particular to a gear box cover that can be quickly installed. Background Art

[0002] In the field of industrial machinery, gearboxes are key components of the transmission system. Their main functions include transmitting power, adjusting speed, changing transmission direction, distributing power, and changing torque. In wind turbines, gearboxes are used to convert the low-speed rotation of the wind wheel into the high-speed rotation required by the generator, thereby effectively generating electricity. In addition, gearboxes can also reduce the vibration and noise of mechanical equipment and improve the stability and reliability of the equipment.

[0003] The gearbox cover on the top of the gearbox is an important accessory that seals the inside of the gearbox, keeps the lubricating oil from leaking, and prevents dust and other external impurities from entering the gearbox. It also protects the internal precision parts such as gears and bearings, reduces wear and extends the service life of the gearbox. During maintenance and overhaul, the gearbox cover provides a convenient access port so that staff can inspect, clean and replace parts.

[0004] However, the existing gear box cover is usually fixed by threaded rotation, which undoubtedly increases the workload and time cost and reduces the maintenance efficiency. Especially in the case of emergency repairs or quick response, the slowness of this installation method may affect the production efficiency and normal operation of the equipment. Summary of the invention

[0005] The purpose of this application is to solve the problem of wasting time costs and affecting production efficiency in the prior art.

[0007] An inner support assembly is installed inside the box cover, and the inner support assembly is used to fix the box cover inside the oil inlet hole. A blocking block is fixedly installed inside the oil inlet hole.

[0008] The inner support assembly includes a support ring, a first slide groove, a bayonet, a central axis and a conical block. The inner wall of the oil inlet hole is fixedly connected with the support ring. The block is located on the top of the support ring. A plurality of first slide grooves are provided inside the block. A bayonet is slidably installed inside the first slide groove. The bottom of the block is fixedly connected with the central axis. The bottom of the central axis is fixedly connected with the conical block. The conical block is located between a plurality of bayonet pins.

[0009] Preferably, the box cover comprises a blocking block and a top cover, and the top of the blocking block is slidably mounted with the top cover.

[0010] Further preferably, a limiting groove is provided on the inner wall of the first sliding groove, and a limiting ring is fixedly connected to the outer wall of the bayonet, and the limiting ring is located inside the limiting groove.

[0011] Further preferably, a spring is installed inside the blocking block, and the spring is located at the top of the conical block.

[0012] Further preferably, a plurality of second slide grooves are formed on the outer wall of the block, a clamping groove is formed on the outer wall of the block, a plurality of clamping blocks are fixedly connected to the inner wall of the top cover, and the clamping blocks are located inside the second slide grooves.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] (1) By setting, the oil inlet hole, the support ring, the block, the first slide groove, the top cover, the pin, the middle shaft, the conical block, the spring, the slot and the block, when the box cover needs to be installed inside the oil inlet hole, the block is placed inside the oil inlet hole and located on the top of the support ring. At this time, the spring pushes the conical block to move downward, and the conical block can push the pin inside the first slide groove outward to be stuck inside the oil inlet hole, and then the block on the inner wall of the top cover is stuck inside the slot, so that the box cover can be fixed inside the oil inlet hole; when the box cover needs to be removed, the top cover is rotated to make the block on the inner wall of the top cover fall off the slot, and then the top cover is pulled upward, and at the same time, the conical block is driven upward by the middle shaft, and then the pin has no outward supporting force, and then the block is driven upward by the top cover, and then the pin will retract, and the block can be taken out from the inside of the oil inlet hole, so that the gear box cover can be installed quickly and conveniently, solving the problem of wasting time and cost affecting production efficiency in the prior art.
