Description

Technical Field

[0001] This invention relates to the field of speed measurement equipment technology, specifically to a split-type encoder integrated mechanism. Background Technology

[0002] Currently, most conventional methods for measuring shaft speed on the market use a split-mount speed encoder. This involves fixing a circular encoder (magnetic ring) to the shaft and a reading head to the equipment housing or a dedicated bracket. In the radial direction, a gap plate is inserted between the reading head and the magnetic ring. The reading head is then pressed firmly against the gap plate, the fixing screws are tightened, and finally the gap plate is removed. In the axial direction, the reading head bracket mounting screws are adjusted to ensure complete alignment between the two components.

[0003] Existing encoder installation methods place high demands on the installer's experience and skills. During installation, it's easy to encounter issues such as excessive radial clearance and axial misalignment. Installers must continuously correct these errors to ensure proper clearance and position, thereby guaranteeing measurement accuracy.

[0004] Therefore, a solution is needed. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: A split encoder integrated mechanism includes a rotating spindle and a split encoder integrated mechanism, wherein the split encoder integrated mechanism is disposed on the rotating spindle; The split encoder integrated mechanism includes a positioning cone sleeve one, a bolt hole one, a positioning cone sleeve two, a bolt hole two, a fastening screw one, an encoder magnetic ring, a dustproof positioning ring, a bolt hole three, an encoder reading head, a bolt hole four, a bearing outer ring bracket, a bolt hole five, a fastening screw two, and a support bearing. The positioning cone sleeve one is wrapped around the rotating main shaft. The bolt holes one are evenly distributed on the positioning cone sleeve one. The positioning cone sleeve two is located to the right of the positioning cone sleeve one. The bolt holes two are located on the positioning cone sleeve two corresponding to the positions of each bolt hole one. The fastening screw one is located inside the bolt holes one and bolt holes two. The encoder magnetic ring is set... On the outer diameter of the second positioning cone sleeve, the dustproof positioning ring is located at the right end of the encoder magnetic ring, the third bolt hole is located at the top of the dustproof positioning ring, the encoder reading head is located at the top of the encoder magnetic ring, the fourth bolt hole is located inside the encoder reading head corresponding to the position of the third bolt hole, the bearing outer ring bracket is wrapped around the left end of the dustproof positioning ring, the fifth bolt hole is located on the bearing outer ring bracket corresponding to the position of the fourth bolt hole, the second fastening screw is located inside the third, fourth and fifth bolt holes, and the support bearing is located at the left end of the encoder magnetic ring and the encoder reading head.

[0007] Preferably, there are four positioning cone sleeves arranged in a circular structure, with the left half of each positioning cone sleeve having a fan-shaped structure and the right half having an arc-shaped structure, and the bolt hole is located in the middle of the outer half of the fan-shaped structure of each positioning cone sleeve.

[0008] Preferably, the second positioning cone sleeve has a ring structure and the part where the second positioning cone sleeve fits into the first positioning cone sleeve has a cone-shaped structure.

[0009] Preferably, there are two of each of the three bolt holes, four bolt holes and five bolt holes, and they are evenly distributed one in front of the other.

[0010] Preferably, the upper half of the encoder reading head extends upward through the top of the bearing outer ring bracket, and the right end of the encoder reading head is located on the same plane as the right end of the bearing outer ring bracket.

[0011] Preferably, the supporting bearing is located inside the bearing outer ring bracket, and the left end of the supporting bearing and the left end of the bearing outer ring bracket are on the same plane.

[0012] This invention provides a split-type encoder integrated mechanism. It has the following advantages: 1. The four-piece enclosing positioning cone sleeve one and positioning cone sleeve two are self-centering through cone surface extrusion. The pre-installed integrated encoder magnetic ring, encoder reading head, support bearing, and bearing outer ring bracket can automatically lock the standard radial clearance after being fitted into the rotating spindle, eliminating the need for manual calibration of the clearance plate and reducing the installation and operation threshold.

[0013] 2. The support bearing, bearing outer ring bracket, and dustproof positioning ring are pre-locked by multiple sets of bolt holes and fastening screws, which pre-fixes the axial relative position of the encoder magnetic ring and the encoder reading head. After assembly, there is no need to repeatedly adjust the position, thus completely avoiding the problem of axial deviation.

[0014] 3. This mechanism can pre-assemble the encoder magnetic ring, dustproof positioning ring, encoder reading head, bearing outer ring bracket, support bearing and positioning cone sleeve II in advance. After the whole assembly is installed on the rotating spindle, only the first fastening screw needs to be tightened to complete the assembly, saving multiple debugging steps and effectively improving assembly efficiency.

[0015] 4. The dustproof positioning ring is located at the right end of the encoder magnetic ring. It can separate the encoder magnetic ring from the bearing outer ring bracket to achieve precise axial positioning, and can also isolate dust and oil to protect the sensing area, stabilize measurement accuracy and reduce maintenance.

[0016] 5. Positioning cone sleeve one and positioning cone sleeve two have circumferentially distributed bolt holes one and two, which, together with fastening screw one, evenly grip the rotating spindle. Paired bolt holes three, four, and five, together with fastening screw two, lock the encoder reading head. This design prevents loosening and deviation during long-term operation, resulting in better measurement stability.

[0017] 6. The support bearing housed inside the outer ring bracket of the bearing and located at the left end of the encoder magnetic ring and encoder reading head can bear the radial load of the mechanism, avoid the load impacting the sensing mating surface, reduce the wear of the core components of the encoder, and reduce the failure rate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 The present invention provides a technical solution that includes a rotating spindle 1 and a split encoder integrated mechanism 2, wherein the split encoder integrated mechanism 2 is disposed on the rotating spindle 1. The split encoder integrated mechanism 2 includes a positioning cone sleeve 1 21, a bolt hole 1 22, a positioning cone sleeve 2 23, a bolt hole 24, a fastening screw 1 25, an encoder magnetic ring 26, a dustproof positioning ring 27, a bolt hole 3 28, an encoder reading head 29, a bolt hole 4 210, a bearing outer ring bracket 211, a bolt hole 5 212, a fastening screw 213, and a support bearing 214. The positioning cone sleeve 1 21 is wrapped around the rotating main shaft 1. The bolt holes 1 22 are evenly distributed on the positioning cone sleeve 1 21. The positioning cone sleeve 2 23 is located to the right of the positioning cone sleeve 1 21. The bolt holes 24 are located on the positioning cone sleeve 2 23 corresponding to the positions of each bolt hole 1 22. The fastening screw 1 25 is located inside the bolt holes 1 22 and bolt holes 24. The encoder magnetic ring 26 is mounted on the outer diameter of the positioning cone sleeve 23. The dustproof positioning ring 27 is mounted on the right end of the encoder magnetic ring 26. The bolt hole 3 28 is mounted on the top of the dustproof positioning ring 27. The encoder reading head 29 is mounted on the top of the encoder magnetic ring 26. The bolt hole 4 210 is positioned inside the encoder reading head 29, corresponding to the position of bolt hole 3 28. The bearing outer ring bracket 211 is mounted on the left end of the dustproof positioning ring 27. The bolt hole 5 212 is positioned on the bearing outer ring bracket 211, corresponding to the position of bolt hole 4 210. The fastening screw 213 is mounted inside bolt holes 3 28, 4 210, and 5 212. The support bearing 214 is mounted on the left end of the encoder magnetic ring 26 and the encoder reading head 29.

[0022] In detail, there are four positioning cone sleeves 21 arranged in a circular structure. The left half of each positioning cone sleeve 21 is fan-shaped and the right half is arc-shaped. The bolt hole 22 is located in the middle of the outer half of the fan-shaped structure of each positioning cone sleeve 21.

[0023] The positioning cone sleeve 23 has a ring structure and the part where the positioning cone sleeve 23 fits with the positioning cone sleeve 21 has a cone-shaped structure.

[0024] There are two bolt holes 3 (28), 4 (210), and 5 (212), and they are evenly distributed one after the other.

[0025] The upper half of the encoder reading head 29 extends upward through the top of the bearing outer ring bracket 211, and the right end of the encoder reading head 29 is on the same plane as the right end of the bearing outer ring bracket 211.

[0026] The support bearing 214 is located inside the bearing outer ring bracket 211, and the left end of the support bearing 214 and the left end of the bearing outer ring bracket 211 are on the same plane.

[0027] Solution Analysis: 1. Positioning cone sleeve 1 21 and positioning cone sleeve 2 23 rely on the self-centering fit of the cone surface to achieve automatic and precise control of radial clearance, solving the problem of difficult control of radial clearance in existing technologies. The four-piece enclosed fan-shaped arc slope structure positioning cone sleeve 1 21 is paired with the cone-shaped end face positioning cone sleeve 23. Before assembling the split encoder integrated mechanism 2, the encoder magnetic ring 26, encoder reading head 29, support bearing 214, and bearing outer ring bracket 211 are pre-integrated and locked as a whole. After the whole is put into the rotating main shaft 1, only the fastening screw 1 25 needs to be tightened. The cone surfaces of positioning cone sleeve 1 21 and positioning cone sleeve 23 squeeze and shrink each other, automatically completing the coaxial centering with the rotating main shaft 1. The radial distance between encoder magnetic ring 26 and encoder reading head 29 is fixed and formed. There is no need to manually insert gap pieces for repeated calibration, eliminating the defects of excessive radial clearance and uneven clearance caused by manual operation, and reducing the dependence of installation on the practical experience of workers.

[0028] 2. The bearing outer ring bracket 211, support bearing 214, and dustproof positioning ring 27 achieve precise axial alignment in one go, eliminating axial misalignment. The support bearing 214 is installed inside the bearing outer ring bracket 211, with its left end flush with the left end of the bearing outer ring bracket 211. The right end of the encoder reading head 29 is flush with the right end of the bearing outer ring bracket 211. A dustproof positioning ring 27 is placed between the encoder magnetic ring 26 and the bearing outer ring bracket 211. All components are pre-locked together by bolt holes 3 28, 4 210, and 5 212, along with fastening screws 2 213. The axial relative position of the encoder magnetic ring 26 and the encoder reading head 29 is completely fixed during the pre-assembly stage. After the entire machine is fitted with the rotating spindle 1, there is no need to repeatedly adjust the bracket screws to correct the axial position, structurally avoiding axial misalignment between the magnetic ring and the reading head, and greatly simplifying the assembly process.

[0029] 3. The pre-assembled integrated structure significantly improves assembly efficiency and reduces rework and debugging workload. During assembly, the encoder magnetic ring 26, dustproof positioning ring 27, encoder reading head 29, bearing outer ring bracket 211, support bearing 214, and positioning cone sleeve 23 are pre-assembled on the outside of the equipment. The reading head assembly is then locked using fastening screw 213. The positioning cone sleeve 21, with fastening screw 25 but not yet tightened, is then attached to the left side of positioning cone sleeve 23, forming a complete split-type encoder integrated mechanism 2. The entire assembly can be completed by simply fitting it onto the rotating spindle 1 and tightening all fastening screws 25 once, eliminating the need for multiple disassemblies and repeated calibrations of clearances and axial positions required in traditional solutions, significantly reducing assembly time.

[0030] 4. The dustproof positioning ring 27 serves both positioning and dustproof functions, extending the encoder's service life. The dustproof positioning ring 27 is located at the right end of the encoder magnetic ring 26. On the one hand, it serves as an axial positioning partition, precisely separating the encoder magnetic ring 26 from the bearing outer ring bracket 211 to ensure axial assembly dimensions. On the other hand, it seals the gap between the encoder magnetic ring 26 and the bearing outer ring bracket 211, preventing dust and oil from entering the sensing area of ​​the encoder magnetic ring 26 and the encoder reading head 29, preventing impurities from accumulating and causing distortion of the sensing signal, stabilizing the speed measurement accuracy, and reducing the frequency of equipment maintenance.

[0031] 5. The multi-bolt symmetrical locking structure ensures a firm overall assembly and strong operational stability. Positioning cone sleeve 1 21 has evenly spaced bolt holes 22, and positioning cone sleeve 23 has corresponding bolt holes 24. Multiple sets of fastening screws 25 are evenly tightened along the circumference, so that the positioning cone sleeve 1 21 is evenly stressed during contraction and is tightly gripped with the rotating main shaft 1 without any off-center load. The bolt holes 28 of the dustproof positioning ring 27, the bolt holes 210 of the encoder reading head 29, and the bolt holes 212 of the bearing outer ring bracket 211 are all arranged in pairs, front and back, and are matched with fastening screws 213 to lock the encoder reading head 29 in both directions. During long-term operation of the equipment, there will be no loosening of the reading head or displacement of the magnetic ring, thus continuously ensuring the accuracy of speed detection.

[0032] 6. The 214 support bearing shares the radial load, reducing wear on the encoder assembly. The support bearing 214 is arranged at the left end of the encoder magnetic ring 26 and the encoder reading head 29 and is housed inside the bearing outer ring bracket 211. When the whole machine is running, the support bearing 214 bears the radial load of the split encoder integrated mechanism 2, avoiding the load from acting directly on the sensing mating surface of the encoder magnetic ring 26 and the encoder reading head 29, reducing the frictional wear of the magnetic ring and the reading head, and reducing the probability of failure.

[0033] Working principle: Install the encoder magnetic ring 26, dustproof positioning ring 27, encoder reading head 29, bearing outer ring bracket 211, and support bearing 214 onto the positioning cone sleeve 23 in sequence. Secure the encoder reading head 29 with the second fastening screw 213. Then, install the positioning cone sleeve 21 onto the left side of the positioning cone sleeve 23 with the first fastening screw 25. Do not tighten the first fastening screw 25 at this time; leave it loose. After installing the integrated split encoder mechanism 2 onto the rotating main shaft 1, tighten the first fastening screw 25 through the conical fit between the positioning cone sleeve 21 and the positioning cone sleeve 23 to complete the assembly process.

[0034] Technical effects of implementing this solution: This solution utilizes a self-centering pre-assembled integrated structure with a tapered sleeve to precisely position the encoder's radial clearance and axial position in one go. This eliminates the reliance on operator experience in traditional assembly methods, simplifies the assembly process, and improves assembly efficiency. At the same time, it relies on dustproof and bearing-supporting structures to stabilize detection accuracy and extend the encoder's service life. The locking structure ensures long-term operation without loosening. This solution comprehensively addresses multiple shortcomings of existing split encoders, such as cumbersome assembly and debugging, poor alignment accuracy, and insufficient measurement stability.

[0035] The present invention comprises: 1-rotating spindle; 2-split encoder integrated mechanism; 21-positioning cone sleeve one; 22-bolt hole one; 23-positioning cone sleeve two; 24-bolt hole two; 25-fastening screw one; 26-encoder magnetic ring; 27-dustproof positioning ring; 28-bolt hole three; 29-encoder reading head; 210-bolt hole four; 211-bearing outer ring bracket; 212-bolt hole five; 213-fastening screw two; 214-support bearing. These components are all general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that existing encoder installation methods place high demands on the installation experience and skills of installers. During installation, it is easy to have excessive radial clearance and relative misalignment in the axial direction. Installers must continuously correct these errors to ensure appropriate clearance and position, thereby guaranteeing measurement accuracy. This solution utilizes a pre-assembled self-centering integrated structure with a tapered sleeve to accurately position the encoder's radial and axial positions, simplifying assembly and lowering the operational threshold. Furthermore, it stabilizes measurement accuracy and extends service life through dustproof, load-bearing, and locking structures, thus solving the problems of difficult assembly and debugging, misalignment, and unstable operation of traditional encoders.
