Abstract
The invention relates to a transmission mechanism, in particular to a connecting structure between transmission shafts of the transmission mechanism and specifically provides a displacement compensation structure for transmission shaft connection of the transmission mechanism. The displacement compensation structure for the transmission shaft connection of the transmission mechanism comprises the transmission shafts, wherein the transmission shafts sleeve a spline sleeve and fixedly connected with the spline sleeve, and a spline shaft penetrates the spline sleeve and can slide in the spline sleeve. By adopting the displacement compensation structure, the size deviation caused by machining and civil engineering and installation of engineering equipment can be compensated, meanwhile the installing efficiency is improved, and dismounting is convenient.
Description
Technical field
The present invention relates to driving mechanism, the linkage structure between the transmission shaft of driving mechanism especially, is specially the bit shift compensation structure of the transmission shaft connection of driving mechanism.
Background technique
Traditional running shaft connects to be mostly axle with axle sleeve employing parallel key or to sell and is connected, and this Placement is commonplace, but uncertain at axle and axle sleeve position, need to have under the occasion of slip, and it is not all right using parallel key or pin Placement.As part axle and axle sleeve in the valve teletransmission mechanism in nuclear power station just need to have corresponding slip, valve teletransmission mechanism is coupled together by a lot of component, if it is obviously not all right that the axle in whole valve teletransmission mechanism all adopts parallel key or pin to be connected with axle sleeve, because the installation of valve teletransmission mechanism is all to install at the construction field (site), such accurate of impossible the camera processing of on-the-spot civil engineering, the maximum error that has several centimeters in installation process, this just need to have a kind of other Placement to substitute traditional Placement.
Summary of the invention
The goal of the invention of patent of the present invention is to provide the size deviation that a kind of compensation brings because of machining, engineering equipment civil engineering and installation, and can improve the bit shift compensation structure of transmission shaft connection of the driving mechanism of installation efficiency and convenient disassembly simultaneously.
The goal of the invention of patent of the present invention is achieved in that
The bit shift compensation structure of the transmission shaft connection of driving mechanism, comprises transmission shaft, and described driving sleeve is on spline housing, and described transmission shaft is fixedly connected with described spline housing, and splined shaft is arranged in described spline housing and can in described spline housing, slides.
Further, described transmission shaft and described spline housing are for being welded and fixed.
Further, described splined shaft is provided with 6,8 or 10 keyway first, and described spline housing is provided with keyway second corresponding with keyway on described splined shaft and coupling.
The achieved beneficial effect of the present invention is:
1), effectively compensate because building and install Conncetion cimension deviation between the transmission shaft bringing on machining, engineering equipment.
2), because adopting splined shaft and spline housing to coordinate, the centering that transmission shaft connects, guidance quality is better.
3), easily installation and detaching structure are simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is transmission shaft connection diagram of the present invention;
Fig. 2 is generalized section of the present invention.
Wherein, 1 splined shaft, 11 keyway first, 12 keyway second,
2 spline housings, 3 transmission shafts,
L1 spline housing length, compensating error length on L2 splined shaft, compensating error length under L3 splined shaft.
Embodiment
Beneficial effect in order more properly to describe the present invention and to bring, is described further the present invention below in conjunction with accompanying drawing, but protection scope of the present invention is not limited to the content that embodiment is explained.
The bit shift compensation structure of the transmission shaft connection of driving mechanism, transmission shaft 3, transmission shaft 3 is placed on spline housing 2, transmission shaft 3 is welded and fixed with spline housing 2, splined shaft 1 is provided with 8 keyway first 11, spline housing 2 is provided with 8 keyway second 12, and splined shaft 1 and spline housing 2 cooperatively interact, and splined shaft 1 is arranged in spline housing 2 and can in spline housing 2, slides.
Transmission shaft of the present invention connects employing splined shaft and is connected with spline housing, does not need bearing pin, and splined is multiple tooth work, bearing capacity is high, centering, guidance quality are good, and tooth root is more shallow, and stress is concentrated less, axle and hub strength reduction are little, in this splined shaft is connected with spline housing, it is longer that splined shaft 1 is done, and guarantees that splined shaft 1 slides and has enough length in spline housing 2, this Placement is also more convenient to dismounting, only needs very like a cork splined shaft 1 to be extracted from spline housing 2 during dismounting.Also can effectively compensate Conncetion cimension deviation between the transmission shaft bringing because of machining, engineering equipment civil engineering and installation.
Between the transmission shaft bringing because of machining, engineering equipment civil engineering and installation during transmission shaft connects Conncetion cimension deviation because of the periphery of compensation can be compensating error length L 3 under compensating error length L 2 on L2 splined shaft, L3 splined shaft.
