[0002] The winding turbine box is mainly used to convert power into mechanical energy, which can provide stable torque and control speed to ensure product quality.

[0003] The winding turbine box includes a housing composed of two sets of upper and lower housings, gears, bearings, housings and turbines. When in use, power is transmitted to the worm gear mechanism in the turbine box, which transmits the motion to the axle, and drives the output gear to rotate through the axle.

[0004] The turbine case shell, which is composed of two sets of upper and lower shells, has a large gap, resulting in it being not tight enough. When the equipment runs at high speed, it will cause vibration, resulting in wear of the turbine case, which in turn leads to increased failures and higher maintenance costs. Utility Model Content

It is characterized in that a sealing assembly is fixedly installed on the upper shell near the position of the lower shell; and a groove body for the sealing assembly to be inserted into is opened on the lower shell, and the sealing assembly is engaged so that the upper shell and the lower shell are sealed. The sealing assembly includes at least one group of extended ends and inclined ends connected to the extended ends.

[0006] Optionally, the inclined end portion continuously extends straight toward direction c, and the extended end portion continuously extends toward direction b, until two groups of extension lines intersect to form an angle α, and the angle α is 115°-155°.

[0007] Optionally, a sealing elastic part is arranged on the end face of the sealing assembly near the lower shell body, and the cross-section of the sealing elastic part is an arrow-shaped arc-shaped part, a sealing groove for the sealing elastic part to extend into is opened in the groove body, and the outer wall of the sealing elastic part is in conflict with the inner wall of the sealing groove.

[0008] Optionally, a bearing assembly is installed on the worm of the turbine worm mechanism; and the wheel axle is connected through the bearing assembly, the bearing assembly includes a bearing, and a sealing seat is installed on the bearing, and the sealing seat is clamped and connected to a sealing ring.

[0009] Optionally, the sealing seat and the sealing ring are both made of fluororubber material.

[0010] Optionally, a sealing connector is installed on the end face of the sealing ring near the sealing seat, at least one group of clamping blocks is arranged around the circumference of the sealing connector outside, at least one group of sealing blocks is arranged around the circumference of the sealing connector inside, and the cross-section of the sealing block is L-shaped.

[0011] Optionally, a mounting frame is provided on the sealing seat, and a card slot for the card block to extend into is opened on the outer ring of the mounting frame to achieve card-engagement connection.

[0012] Optionally, a sealing groove for the sealing block to extend into is formed on the inner ring of the mounting frame, so that the sealing block contacts the inner wall of the sealing groove.

[0013] In summary, the beneficial effects of the utility model are:

[0014] (1) The utility model adds a sealing component so that the upper shell and the lower shell are sealed, thereby reducing the gap between the upper shell and the lower shell, improving the tightness, reducing wear, and thus reducing failures and maintenance costs.

[0015] (2) When the utility model is in use, the sealing assembly enables the upper shell and the lower shell to be sealed and connected, thereby improving the sealing performance. At the same time, by adding a sealing ring and a sealing connector, during installation, it is only necessary to press the sealing connector into the sealing seat. When the sealing block is automatically inserted into the sealing groove, the outer wall of the sealing block is completely fitted with the inner wall of the sealing groove by its own elastic deformation, thereby improving the tight connection between the sealing ring and the sealing seat. Therefore, when the turbine worm mechanism disposed inside the housing rotates and vibrates, the vibration is transmitted to the bearing assembly through the worm, and the sealing seat and sealing ring made of fluororubber material absorb the vibration transmitted along the radial direction of the worm, weaken the vibration, and thus reduce the probability of wear of the turbine housing.

[0039] like Figures 1 to 7 As shown, this embodiment provides a winding worm gear box 100 with an anti-wear device, including a housing composed of an upper housing 10 and a lower housing 40, and a drive system 30 is fixedly installed on the outer wall of the housing by fastening screws, and the drive system 30 is preferably a motor, and the driving end of the drive system 30 passes through the outer wall of the housing, and a turbine of a worm gear mechanism 60 is installed, and the turbine of the worm gear mechanism 60 is meshed and connected to the worm. In this embodiment, by starting the drive system, the turbine is driven to drive the worm.

[0040] A sealing assembly 70 is fixedly installed on the upper shell 10 near the lower shell 40 by means of a fixing connection such as gluing or welding; and a groove 401 is provided on the lower shell 40 for the sealing assembly 70 to be inserted into, so that the upper shell 10 and the lower shell 40 are sealed.

[0041] The traditional turbine housing composed of two sets of upper and lower housings has a large gap between them, which leads to insufficient tightness. When the equipment runs at high speed, it will cause vibration, resulting in wear of the turbine housing, which in turn leads to increased failures and increased maintenance costs. In order to solve the above technical problems, the sealing between the two sets of housings is improved. Figure 1 , Figure 2 and Figure 7As shown, the sealing assembly 70 includes at least one group of extended ends 701 and an inclined end 702 connected to the extended end 701, and the inclined end 702 continues to extend straight toward direction c, and the extended end 701 continues to extend toward direction b until the two groups of extension lines intersect to form an angle α, and the angle α is 115°-155°. When the angle α is set to 115°, the inclined end 702 is tightly fitted with the inclined surface of the groove body 401, thereby improving the tightness between the upper and lower groups of shells.

[0042] Furthermore, a sealing elastic member 703 is arranged on the end face of the sealing assembly 70 near the lower shell body 40, and the cross-section of the sealing elastic member 703 is an arrow-shaped arc-shaped arrangement, and a sealing groove for the sealing elastic member 703 to extend into is opened in the groove body 401, and the outer wall of the sealing elastic member 703 is in conflict with the inner wall of the sealing groove.

[0043] In this embodiment, when assembling the upper shell 10 and the lower shell 40, it is only necessary to snap the upper shell 10 onto the lower shell 40, and then turn the fastening screws so that the sealing assembly 703 provided on the upper shell 10 is inserted into the groove body 401 until the sealing elastic member 703 provided on the sealing assembly 703 extends into the sealing groove, thereby making the upper shell 10 and the lower shell 40 sealed and connected, thereby improving their sealing performance.

[0044] Furthermore, the thickness of the sealing assembly is 30 mm, and the thickness of the sealing elastic member 703 is 15 mm.

[0045] When the equipment runs at high speed, it will cause vibration, which will cause wear on the turbine box. To solve the above technical problems, please refer to Figure 3 , Figure 4 and Figure 5 As shown, a bearing assembly 80 is installed on the worm of the worm gear mechanism 60; and the wheel shaft 20 is connected through the bearing assembly 80, and the wheel shaft 20 passes through the box and is connected to external equipment. The bearing assembly 80 includes a bearing 801, and a sealing seat 804 is fixedly installed on the bearing 801 by a fastening screw, and the sealing seat 804 is clamped and connected to a sealing ring 803.

[0046] Furthermore, the sealing seat 804 and the sealing ring 803 are both made of fluororubber material, which has good elasticity.

[0047] In this embodiment, when the turbine worm gear mechanism disposed inside the housing rotates and vibrates, the vibration is transmitted to the bearing assembly 80 through the worm gear, and the sealing seat and sealing ring 803 made of fluororubber material absorb the vibration transmitted along the radial direction of the worm gear, thereby weakening the vibration and reducing the probability of wear of the turbine housing.

[0048] Furthermore, a sealing connector 802 is installed on the end surface of the sealing ring 803 near the sealing seat 804 by means of a fixed connection such as gluing or welding, and at least one group of clamping blocks 8021 is arranged around the circumference of the sealing connector 802, and at least one group of sealing blocks 8022 is arranged around the circumference of the sealing connector 802, and the cross-section of the sealing block 8022 is L-shaped.

[0049] Furthermore, a mounting frame 8041 is provided on the sealing seat 804, and a card slot 8042 for the card block 8021 to extend into is opened on the outer ring of the mounting frame 8041, so as to achieve a card-engagement connection.

[0050] Furthermore, a sealing groove for the sealing block 8022 to extend into is provided on the inner ring of the mounting frame 8041, so that the sealing block 8022 is in conflict with the inner wall of the sealing groove.

[0051] In this embodiment, when the sealing ring 803 is installed on the sealing seat 804, it is only necessary to open a slot 8042 on the outer ring of the mounting frame 8041 for the clamping block 8021 to extend into, so that it can be snap-fitted and connected. At the same time, the sealing block 8022 is automatically snapped into the sealing groove set on the inner ring of the mounting frame and snap-fitted and connected.

[0052] Furthermore, the sealing block 8022 is made of elastic rubber material. By utilizing the elastic variable of the sealing block itself, when the sealing block is automatically inserted into the sealing groove, its own elastic deformation is utilized to make the outer wall of the sealing block completely fit with the inner wall of the sealing groove, thereby improving the tight connection between the sealing ring and the sealing seat.

[0053] In this embodiment, by adding a sealing ring and a sealing connector 802, during installation, it is only necessary to press the sealing connector into the sealing seat. When the sealing block is automatically inserted into the sealing groove, the outer wall of the sealing block is completely fitted with the inner wall of the sealing groove by its own elastic deformation, thereby improving the tight connection between the sealing ring and the sealing seat. Therefore, when the turbine worm mechanism disposed inside the housing rotates and vibrates, the vibration is transmitted to the bearing assembly 80 through the worm, and the sealing seat and the sealing ring 803 made of fluororubber material absorb the vibration transmitted along the radial direction of the worm, weaken the vibration, and thus reduce the probability of wear of the turbine housing.

[0054] The use process and working principle of this utility model:

[0055] When assembling the upper shell 10 and the lower shell 40, the utility model only needs to snap the upper shell 10 onto the lower shell 40, and then rotate the fastening screws to make the sealing assembly 703 arranged on the upper shell 10 snap into the groove body 401, until the sealing elastic member 703 arranged on the sealing assembly 703 extends into the sealing groove, so that the upper shell 10 and the lower shell 40 are sealed and connected, thereby improving their sealing performance; at the same time, by adding a sealing ring and a sealing connector 802, during installation, it is only necessary to press the sealing connector into the sealing seat, and when the sealing block is automatically snapped into the sealing groove, its own elastic deformation is utilized to make the outer wall of the sealing block completely fit with the inner wall of the sealing groove, thereby improving the tight connection between the sealing ring and the sealing seat. Therefore, when the turbine worm mechanism arranged inside the housing rotates and vibrates, the vibration is transmitted to the bearing assembly 80 through the worm, and the sealing seat and sealing ring 803 made of fluororubber material absorb the vibration transmitted along the radial direction of the worm, thereby weakening the vibration and reducing the probability of wear of the turbine housing.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
