Description

Technical Field

[0001] The present invention relates to the technical field of adapter sleeves, and more particularly to an adapter sleeve with excellent installation adaptability. Background Art

[0002] An adapter sleeve is the most commonly used component for positioning a bearing with a tapered hole on a cylindrical shaft. The adapter sleeve consists of parts such as an adapter bush, a lock nut, and a lock washer, and is used to fix a tapered bore self-aligning bearing (self-aligning ball bearing, self-aligning roller bearing) on a shaft without a shoulder. It has a simple structure, reliable operation, convenient bearing replacement, and is widely used in industries such as textiles, light industry, papermaking, metallurgy, belt transportation, and conveying equipment.

[0003] In the prior art, an adapter sleeve with good installation compatibility, with the publication number of CN 222026168 U, includes a first adapter sleeve and a second adapter sleeve. At one end of the first adapter sleeve away from the thread, symmetrically arranged first circular grooves are provided, and a plurality of card slots are respectively provided in the first circular grooves. The second adapter sleeve is provided with second circular grooves corresponding to the first circular grooves, positioning grooves are respectively provided at one end of the second circular grooves, connecting rods are respectively arranged in the second circular grooves, and positioning blocks are fixedly connected to one ends of the connecting rods. The beneficial effect of this utility model is that card slots are provided inside the adapter sleeve. When the adapter sleeve does not match the bearing, the second adapter sleeve can be fixed to the first adapter sleeve by simply rotating the knob to drive the cylindrical block to connect with the card slots, so that the length of the original adapter sleeve can be extended, different widths of bearings can be adapted, it is more applicable and compatible, and the cost of bearing installation is reduced.

[0004] However, when the existing adapter sleeve is in use, although it can better meet the assembly requirements for different bearings, when the adapter sleeve is connected to the bearing, it is often connected by a single thread. The further clamping and fixing effect of the lock block and the adapter sleeve after threaded connection is not high. When the lock block and the adapter sleeve are threaded together for a long time, thread slipping may occur. Under the high-speed rotation of the bearing, the stability of the connection and use of the adapter sleeve will be reduced, affecting the excellent performance of the adapter sleeve installation and use. At the same time, after the adapter sleeve is assembled, the helix is exposed outside, and the protection effect on the exposed helix is not high, making it easy for impurities to adsorb on the surface of the helix, reducing the convenience of disassembly and assembly of the adapter sleeve, and not meeting the usage requirements of people. Therefore, we propose an adapter sleeve with excellent installation adaptability. Summary of the Invention

[0051] The engaging mechanism 11 includes a locking rod 1105. A connecting shaft 1101 is rotatably connected to the outer wall of the connecting box 10. A connecting gear 1102 is fixedly connected to the outer wall of the connecting shaft 1101. A rotating block 1103 is fixedly connected to the rotating connecting shaft 1101.

One end of the spring 1109 is fixedly connected to a pulling block 1110 fixedly connected to one end of the telescopic rod 1107.

[0052] As Figure 7 shown, a limiting groove 1111 is provided at the connecting part between the outer wall of the swinging rod 1104 and the locking rod 1105. A clamping groove 1112 is provided at the connecting part between the outer wall of the positioning block 6 and the locking rod 1105. The positioning block 6 and the locking rod 1105 are slidably connected. The provision of the limiting groove 1111 helps to limit the sliding of the locking rod 1105.

[0053] As Figure 11 shown, the rotation centers of the swinging rod 1104 and the connecting gear 1102 are on the same horizontal plane as the rotation center of the connecting shaft 1101. The extrusion block 1108 is arranged on the rotation track of the connecting gear 1102. The setting that the rotation centers of the swinging rod 1104 and the connecting gear 1102 are on the same horizontal plane as the rotation center of the connecting shaft 1101 helps to drive the swinging rod 1104 to rotate conveniently.

[0054] As Figure 12 shown, the outer wall contour of the extrusion part between the extrusion block 1108 and the connecting gear 1102 is beveled, and the outer wall contour of the engaging part between the extrusion block 1108 and the connecting gear 1102 is flat.

[0055] As Figure 12 shown, the telescopic rod 1107 and the connecting box 10 form a telescopic structure through the connecting gear 1102 and the extrusion block 1108. The rotation of the connecting gear 1102 drives the telescopic rod 1107 to slide along the outer wall of the connecting box 10 through the connection of the extrusion block 1108, improving the stability of the locking rod 1105 for clamping and fixing the positioning block 6.

[0056] As Figure 6 and Figure 7As shown in the figure, the installation mechanism 12 includes a fixing plate 1201 and a clamping plate 1205. The outer wall of the connection box 10 is fixedly connected with a fixing plate 1201 that fits the outer wall of the locking disc 4. The inner wall of the connection box 10 is rotatably connected with a bevel gear set 1203 through a fixed shaft. The outer wall of the bevel gear set 1203 is fixedly connected with a knob 1202. The outer wall of the bevel gear set 1203 is fixedly connected with a threaded rod 1204 that is rotatably connected with the inner wall of the connection box 10. The outer wall of the threaded rod 1204 is threadedly connected with a clamping plate 1205 that is slidably connected with the outer wall of the connection box 10. A chute 1206 is provided at the connection part between the outer wall of the connection box 10 and the clamping plate 1205. By providing the clamping plate 1205, when it is necessary to improve the stability of the positioning block 6 after installation, the fixing plate 1201 can be fitted to the surface of the locking disc 4, and the knob 1202 is rotated. Through the rotation of the bevel gear set 1203, the threaded rod 1204 is driven to rotate. The rotation of the threaded rod 1204 drives the clamping plate 1205 to slide along the inner wall of the chute 1206. With the cooperation of the fixing plate 1201, the flexibility and stability of the installation between the connection box 10 and the locking disc 4 are improved.

[0057] As Figure 7 shown, the threaded rod 1204 and the connection box 10 form a rotating structure through the knob 1202 and the bevel gear set 1203. The clamping plate 1205 and the chute 1206 form a sliding structure through the threaded rod 1204. It is beneficial to the rotation of the knob 1202. Through the connection of the bevel gear set 1203, the threaded rod 1204 is driven to rotate along the inner wall of the connection box 10, playing a role in driving the clamping plate 1205 to slide conveniently.

[0058] As Figure 7 shown, anti-slip lines are provided at the connection part between the fixing plate 1201 and the locking disc 4, and anti-slip lines are also provided at the connection part between the clamping plate 1205 and the locking disc 4. By providing anti-slip lines at the connection part between the fixing plate 1201 and the locking disc 4, the connection stability between the connection box 10 and the locking disc 4 is improved.

[0059] As Figure 10 and Figure 13 shown,

[0060] The protection mechanism 13 is provided on the outer wall of the protection disc 9;

[0061] The protection mechanism 13 includes an insert block 1301, the outer wall of the clamping rod 1105 is fixedly connected to the connecting rod 1106, the outer wall of the protection plate 9 is fixedly connected to the insert block 1301 which is slidably connected to the outer wall of the connecting rod 1106, the outer wall of the insert block 1301 is provided with a nut 1302, the inner wall of the nut 1302 is threadedly connected to a bolt 1303 which is slidably connected to the outer wall of the clamping rod 1105, and a positioning groove 1304 is provided at the connection part between the outer wall of the connecting rod 1106 and the bolt 1303. 1304 is beneficial for threaded assembly between the outer spiral 7 and the positioning block 6. In order to reduce the exposure of the outer spiral 7 to the outside, causing dust absorption and affecting the cumbersomeness of subsequent disassembly of the positioning block 6 on the outer spiral 7, after the positioning block 6 is installed, the insert block 1301 is inserted into the outer wall of the connecting rod 1106, and the bolt 1303 is rotated to pass through the limit of the nut 1302, so that the bolt 1303 is inserted into the positioning groove 1304, so as to play the role of the protective plate 9 in effectively protecting the exposed spiral.

[0062] like Figure 13 As shown, a slot is provided at the connection position between the inner wall of the plug block 1301 and the connecting rod 1106, and the inner wall contour of the positioning groove 1304 is adapted to the outer wall contour of the bolt 1303, which is beneficial to the provision of a slot at the connection position between the inner wall of the plug block 1301 and the connecting rod 1106, so that the protective plate 9 can effectively protect the exposed spiral, thereby improving the excellent effect of the tightening sleeve in daily work.

[0063] Working principle:

[0064] like Figures 1 - 13 As shown, in daily use, when the adapter sleeve is assembled and connected with the bearing, in order to improve the self-locking stability of the positioning block 6 after the threaded connection, prevent the positioning block 6 from slipping after long-term use, and reduce the stability of the bearing under high-intensity rotation, operate the rotating block 1103, and drive the connecting gear 1102 to rotate under the fixed connection of the connecting shaft 1101. The rotation of the connecting gear 1102 drives the clamping rod 1105 to slide along the inner wall of the limiting groove 1111 through the rotation of the swing rod 1104, and the clamping rod 1105 is inserted into the clamping groove 1112. At the same time, the rotation of the connecting gear 1102 squeezes the extrusion block 1108 and drives the telescopic rod 1107 and the spring 1109 to perform reciprocating lifting motion. When the gear stops rotating, the extrusion block 1108 is timely engaged and fixed to the gear, thereby improving the stability of the clamping and fixing of the positioning block 6 by the clamping rod 1105;

[0065] Next, when it is necessary to improve the stability of the positioning block 6 during use after installation, the fixing plate 1201 is fitted to the surface of the lock plate 4, and the knob 1202 is rotated. Through the rotation of the bevel gear set 1203, the threaded rod 1204 is driven to rotate. The rotation of the threaded rod 1204 drives the clamping plate 1205 to slide along the inner wall of the chute 1206, and with the cooperation of the fixing plate 1201, the flexibility and stability of the installation between the connection box 10 and the lock plate 4 are improved;

[0066] Finally, after the threaded assembly between the outer screw 7 and the positioning block 6, in order to reduce the exposure of the outer screw 7 outside, which causes dust adsorption and affects the tediousness of the subsequent disassembly of the positioning block 6 on the outer screw 7, after the positioning block 6 is installed, the insertion block 1301 is inserted into the outer wall of the connecting rod 1106, and the bolt 1303 is rotated. Through the limit of the nut 1302, the bolt 1303 is inserted into the positioning groove 1304, so that the protective disc 9 effectively protects the exposed screw.

[0067] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
