Abstract
Description
Technical Field
[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer with an integrated output flange. Background Technology
[0002] Traditionally, the output shaft of a speed reducer is connected to the field equipment via bolted flanges. However, under certain operating conditions, especially with frequent start-stop or reversal, the bolts can easily loosen or even fall off, leading to equipment malfunctions and safety hazards. Furthermore, the inability of customers to monitor and tighten the bolts in a timely manner increases the difficulty and cost of equipment maintenance. Loose bolts not only affect the normal operation of the equipment but also cause wear and damage to the connection points, reducing the overall lifespan of the equipment. Utility Model Content
[0003] In view of this, in order to solve the above problems, the purpose of this utility model is to provide a reducer with an integrated output shaft flange, including a housing, characterized in that it further includes: an output shaft and an output shaft flange, wherein the output shaft flange is disposed at one end of the output shaft, the output shaft flange and the output shaft are integrally disposed, and the other end of the output shaft is disposed in the housing.
[0004] In another preferred embodiment, it further includes an outer flange through which the other end of the output shaft passes.
[0005] In another preferred embodiment, one end of the outer flange extends into the housing.
[0006] In another preferred embodiment, it further includes an oil seal disposed between the outer flange and the output shaft.
[0007] In another preferred embodiment, it further includes: a first bearing and a second bearing, both of which are sleeved on the outer edge of the output shaft, the first bearing abutting against one end of the outer flange, and the second bearing located at the other end of the output shaft.
[0008] In another preferred embodiment, it further includes: a gear, which is sleeved on the outer edge of the output shaft and located in the housing, the gear being disposed between the first bearing and the second bearing.
[0009] In another preferred embodiment, a locking cover is provided at the other end of the output shaft, the locking cover is bolted to the output shaft, and the locking cover abuts against the second bearing.
[0010] In another preferred embodiment, it further includes a cap, the cap being disposed on the side of the locking cover away from the second bearing.
[0011] The present invention, by adopting the above-mentioned technical solution, has the following positive effects compared with the prior art: By applying the present invention, an integrated output flange reducer is proposed. By integrating the output flange and the output shaft into a single component, the potential for connection failure due to loose bolts in traditional split structures is eliminated, enhancing connection strength and structural reliability, and extending the service life of the equipment. Simultaneously, it enables effective installation of the oil seal even when the outer flange bore diameter is larger than the output shaft end face, ensuring that the sealing system can both prevent external dust intrusion and internal lubricant leakage, forming a dual protection effect. Furthermore, by simplifying redundant components such as connecting bolts required for split flanges, the number of parts is reduced, which not only simplifies the assembly process and reduces production and warehousing costs, but also reduces maintenance difficulty and manpower input. Users can ensure stable equipment operation without frequent bolt tightening operations. Attached Figure Description
