Description

Technical Field

[0001] The utility model belongs to the technical field of transmission wheel shells, in particular to a new shell for a belt transmission wheel. Background Art

[0002] The belt transmission pulley is a commonly used mechanical transmission device that transmits motion and power through the friction or engagement between the belt and the pulley. The main feature of the belt transmission is that it transmits power through friction while allowing a certain amount of sliding and elastic deformation, and has a buffering and vibration reduction effect. In order to support and protect the belt transmission pulley, a shell is often installed on the surface of the belt transmission pulley.

[0003] The existing housing for the belt transmission pulley is fixed to the pulley surface, generally by a hook. When the pulley rotates at a high speed, the hooks are easily separated from each other, causing the housing to detach from the pulley surface. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a new shell for a belt transmission pulley, which solves the problem that the existing shell for a belt transmission pulley is fixed on the surface of the pulley. Generally, the shell is fixed to the surface of the pulley by a hook. When the pulley rotates at a high speed, the hooks are easily separated from each other, thereby causing the shell to detach from the surface of the pulley.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of shell for a belt transmission wheel, comprising a pulley, wherein rotating shafts are symmetrically provided on both sides of the pulley, a front shell or a rear shell is rotatably installed on the surface of the rotating shaft away from one end of the pulley, and the front shell and the rear shell are wrapped around the surface of the pulley, a positioning column is symmetrically fixedly installed on the bottom of one side of the front shell, a positioning socket is symmetrically provided on the bottom of one side of the rear shell, and the positioning socket and the positioning column correspond to each other, fixing blocks are respectively fixedly installed on both sides and the top of the front shell and the rear shell, and fixing rings are provided on the surfaces of two groups of opposite fixing blocks, a fixing bolt is provided on one side of the fixing block located on the outside of the fixing ring, and mounting plates are respectively provided on the top of the front shell and the rear shell.

[0006] As a further solution of the utility model: a baffle is fixedly installed on one end of the rotating shaft located inside the front shell or the rear shell, and a cross clamp is fixedly installed on the side of the baffle away from the rotating shaft.

[0007] As a further solution of the utility model: a cross slot is provided through the central position of both sides of the pulley, and the cross slot corresponds to the cross clamping block.

[0008] As a further solution of the utility model: a heat dissipation groove is provided at the central position of the bottom of the front shell and the rear shell, belt grooves are symmetrically provided on both sides of the top of the front shell and the rear shell, and two groups of T-shaped slots are symmetrically provided on the top of the inner wall of the front shell and the rear shell.

[0009] As a further solution of the utility model: T-shaped inserting strips are symmetrically fixedly installed on the top of the installation plate, and the T-shaped inserting strips correspond to the T-shaped slots.

[0010] As a further solution of the utility model: two groups of belt slots are provided on the surface of the pulley, a cleaning brush is fixedly installed on the bottom of the mounting plate, and the cleaning brush corresponds to the belt slot.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The novel housing for the belt transmission wheel is provided with a front shell, a rear shell, a fixing block, a fixing bolt and a fixing ring, and the front shell and the rear shell are correspondingly wrapped on both sides of the pulley, so that the fixing blocks on the surfaces of the front shell and the rear shell are correspondingly pressed against each other, and the fixing ring is clamped on the surfaces of the fixing blocks corresponding to the surfaces of the front shell and the rear shell, and the fixing bolts are tightened to press and fix the fixing ring on the surfaces of the fixing blocks, so that the front shell and the rear shell are fixed on the surface of the pulley, and the pulley is shielded and protected to prevent the front shell and the rear shell from being separated from each other due to the high-speed rotation of the pulley, and at the same time, the front shell and the rear shell are conveniently removed from the surface of the pulley, and the belt is controlled to be sleeved on the surface of the pulley.

[0013] 2. The new shell for the belt transmission wheel is provided with a T-slot, a T-slot strip and a cleaning brush. The T-slot strip is inserted into the T-slot corresponding to the top of the front shell or the rear shell, so that the cleaning brush can be clamped and fixed on the top of the front shell or the rear shell. The front shell and the rear shell are then fixed on the surface of the pulley, so that the cleaning brush is clamped into the belt slot corresponding to the surface of the pulley, ensuring that when the pulley rotates inside the front shell and the rear shell, the belt slot slides at the bottom of the cleaning brush, so that the cleaning brush can clean the belt slot, avoiding the belt slipping inside the belt slot due to excessive dust accumulation inside the belt slot.

[0014] 3. The new housing for the belt transmission wheel is provided with a rotating shaft, a baffle, a cross block and a pulley. Two sets of cross blocks are correspondingly inserted into the cross slots on both sides of the pulley, and the front shell and the rear shell are pushed closer to each other until the front shell and the rear shell are tightly fixed on the surface of the pulley, so that the baffle is tightly attached to both sides of the pulley, ensuring that when the rotating shaft is controlled to rotate, the pulley can be driven to rotate synchronously inside the front shell and the rear shell, thereby preventing the pulley from slipping between the baffles.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a new shell for a belt transmission wheel, including a pulley 14, a cross slot 15 is penetrated at the central position on both sides of the pulley 14, and the cross slot 15 corresponds to the cross block 5. By providing the cross block 5 and the cross slot 15, the cross block 5 is inserted into the corresponding cross slot 15 to ensure that the pulley 14 can rotate synchronously with the rotating shaft 3.

[0023] Rotating shafts 3 are symmetrically provided on both sides of the pulley 14, and a baffle 4 is fixedly installed on one end of the rotating shaft 3 located inside the front shell 1 or the rear shell 2, and a cross clamp 5 is fixedly installed on the side of the baffle 4 away from the rotating shaft 3. Because the baffle 4 is provided, when the pulley 14 is clamped on the surfaces of the two groups of cross clamps 5, the baffle 4 is tightly attached to both sides of the pulley 14 to support the pulley 14, ensuring that the pulley 14 does not tilt when rotating.

[0024] A front shell 1 or a rear shell 2 is rotatably mounted on the surface of the rotating shaft 3 away from the pulley 14, and the front shell 1 and the rear shell 2 are wrapped around the surface of the pulley 14. A heat dissipation groove 10 is provided at the central position of the bottom of the front shell 1 and the rear shell 2, and belt grooves 11 are symmetrically provided on both sides of the top of the front shell 1 and the rear shell 2. Due to the heat dissipation groove 10 and the belt groove 11, a large amount of heat will be generated when the belt slides and rubs on the surface of the pulley 14. The heat can be dissipated from the heat dissipation groove 10 and the belt groove 11, thereby preventing heat from accumulating inside the front shell 1 and the rear shell 2 and causing the pulley 14 to wear the belt more severely.

[0025] A positioning column 6 is symmetrically fixedly installed at the bottom of one side of the front shell 1, and a positioning hole 13 is symmetrically provided at the bottom of one side of the rear shell 2, and the positioning hole 13 corresponds to the positioning column 6. By providing the positioning column 6 and the positioning hole 13, when the front shell 1 and the rear shell 2 are relatively wrapped on the surface of the pulley 14, the positioning column 6 is inserted into the corresponding positioning hole 13 to ensure that the front shell 1 and the rear shell 2 are wrapped and fixed on the surface of the pulley 14 without misalignment;

[0026] The front shell 1 and the rear shell 2 are respectively fixedly installed with fixing blocks 7 on both sides and the top, and the surfaces of the two groups of opposite fixing blocks 7 are provided with fixing rings 9, and one side of the fixing block 7 is provided with a fixing bolt 8 on the outside of the fixing ring 9. Because the fixing bolt 8 and the fixing ring 9 are provided, when the front shell 1 and the rear shell 2 are fixed to the surface of the pulley 14, the fixing blocks 7 on the surfaces of the front shell 1 and the rear shell 2 are pressed against each other, and the fixing ring 9 is sleeved on the surfaces of the two corresponding groups of fixing blocks 7, and the fixing bolt 8 is tightened to clamp and fix the fixing ring 9 on the surface of the fixing block 7, so that the front shell 1 and the rear shell 2 are connected and fixed;

[0027] Two groups of T-shaped slots 12 are symmetrically provided at the top of the inner wall of the front shell 1 and the rear shell 2, and mounting plates 17 are provided at the top of the front shell 1 and the rear shell 2. T-shaped inserts 18 are symmetrically fixedly installed on the top of the mounting plate 17, and the T-shaped inserts 18 correspond to the T-shaped slots 12. By providing the T-shaped slots 12 and the T-shaped inserts 18, when the T-shaped inserts 18 are inserted into the corresponding T-shaped slots 12, it is ensured that there is no misalignment when the cleaning brush 19 is fixed to the top of the front shell 1 or the rear shell 2, and at the same time, it is prevented that when the pulley 14 rotates at the bottom of the cleaning brush 19, the cleaning brush 19 slides at the top of the front shell 1 or the rear shell 2 under the action of friction.

[0028] Two groups of belt grooves 16 are provided on the surface of the pulley 14, and a cleaning brush 19 is fixedly installed at the bottom of the mounting plate 17, and the cleaning brush 19 corresponds to the belt groove 16. Because the cleaning brush 19 is provided, after the cleaning brush 19 is inserted into the belt groove 16 corresponding to the surface of the pulley 14, the pulley 14 is controlled to rotate, so that the belt groove 16 rotates at the bottom of the cleaning brush 19, ensuring that the cleaning brush 19 can clean the inside of the belt groove 16.

[0029] The working principle of the utility model is:

[0030] The T-shaped insert strip 18 is inserted into the corresponding T-shaped slot 12, so that the cleaning brush 19 is clamped and fixed to the top of the front shell 1 or the rear shell 2. After the belt is put into the belt slot 16 corresponding to the surface of the pulley 14, the front shell 1 and the rear shell 2 are placed relatively on both sides of the pulley 14, so that the cross block 5 corresponds to the cross slot 15, and the front shell 1 and the rear shell 2 are pushed close to each other until the two groups of cross blocks 5 are completely inserted into the cross slot 15, and the positioning column 6 is inserted into the corresponding positioning plug hole 13, so that the front shell 1 and the rear shell 2 are close to each other, and the fixing ring 9 is put on the surfaces of the two groups of opposite fixing blocks 7, and the fixing bolts 8 are tightened to fix the fixing ring 9 on the surface of the fixing block 7, so that the front shell 1 and the rear shell 2 can be fixed closely to the surface of the pulley 14, and the belt is pulled to make the pulley 14 rotate at the bottom of the cleaning brush 19 under the action of friction, so that the cleaning brush 19 can clean the belt slot 16.
