[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 4 As shown, the emulsion axial motor of the present invention comprises a first cylinder 1, a second cylinder 2, a spiral transmission assembly 3, a positioning assembly 4, a stopper 5 and an output gear 6, the second cylinder 2 is arranged outside the first cylinder 1, the spiral transmission assembly 3 is coaxially arranged at one end of the first cylinder 1 and the second cylinder 2, the positioning assembly 4 is arranged between the first cylinder 1 and the spiral transmission assembly 3, and provides driving force for the spiral transmission assembly 3, the stopper 5 is arranged between the first cylinder 1, the second cylinder 2 and the spiral transmission assembly 3, and the output gear 6 is arranged on the spiral transmission assembly 3 for power output, wherein:

[0032] The first cylinder 1 comprises a first cylinder body 11 and a valve core 12, and the valve core 12 is slidably disposed in the first cylinder body 11;

[0033] The second cylinder 2 comprises a second cylinder body 21, an annular cylinder core 24 and a stop block 25. The annular cylinder core 24 is slidably disposed in the second cylinder body 21. The stop block 25 is disposed in the annular cylinder core 24. The stop block 25 is connected to the screw transmission assembly 3.

[0034] The spiral transmission assembly 3 includes a spiral outer sleeve 31 and a spiral inner core 34 , and the spiral inner core 34 is arranged inside the rotating outer sleeve.

[0035] Furthermore, in the emulsion axial motor of the present invention, the positioning assembly 4 includes a positioning block 41 and a plug rod 42. One end of the plug rod 42 is threadedly engaged with one end of the rod cavity of the valve core 12, and the other end of the plug rod 42 passes through the spiral inner core 34 and is connected to the positioning block 41. When the valve core 12 moves, the spiral inner core 34 is driven to move synchronously by the plug rod 42. The positioning block 41 can prevent the valve core 12 from moving beyond a specified range, and at the same time prevent the plug rod 42 from slipping out of the spiral inner core 34.

[0036] Furthermore, in the emulsion axial motor of the present invention, the outer periphery of the limiter 5 is arranged in a polygonal structure, the middle part of the limiter 5 is threadedly engaged with the valve core 12, the outer periphery of the limiter 5 is arranged with a first raceway 51, and one end of the limiter 5 is arranged with a first spline 52.

[0037] Furthermore, in the emulsion axial motor of the present invention, the interior of one end of the second cylinder body 21 is matched with the outer periphery of the limiter 5, and a second raceway 22 corresponding to the outer periphery of the limiter 5 is arranged inside the second cylinder body 21. The first raceway 51 and the second raceway 22 are connected by balls, so that the valve core 12 drives the limiter 5 to move. The polygonal structure of the outer periphery is connected to the second cylinder body 21, which can ensure that the limiter 5 will not rotate during movement. At the same time, the first raceway 51 and the second raceway 22 are connected by balls, which effectively reduces the friction resistance of the limiter 5 during movement.

[0038] Further, in the emulsion axial motor of the present invention, a second spline 35 is provided at the end of the spiral inner core 34, and the second spline 35 matches the first spline 52. The spiral inner core 34 and the stopper 5 are connected through the first spline 52 and the second spline 35, thereby effectively preventing the spiral inner core 34 from rotating under the interaction force between the spiral inner core 34 and the spiral outer sleeve 31 when the spiral inner core 34 is combined with the stopper 5;

[0039] A first spiral raceway 36 is provided in the circumferential direction of the spiral inner core 34, and a second spiral raceway 32 corresponding to the first spiral raceway 36 is provided on the inner wall of the spiral outer sleeve 31. The first spiral raceway 36 and the second spiral raceway 32 are connected by balls, so that when the spiral inner core 34 and the spiral outer sleeve 31 move relative to each other, the spiral inner core 34 or the spiral outer sleeve 31 performs linear motion or rotational motion under the action of the first spiral raceway 36, the second spiral raceway 32 and the balls.

[0040] Furthermore, in the emulsion axial motor of the present invention, the inner wall of the limit block 25 is threadedly engaged with the annular cylinder core 24, the outer wall of the limit block 25 is provided with a third raceway 26, the inner wall of the second cylinder body 21 is provided with a fourth raceway 23, the third raceway 26 matches the fourth raceway 23, and the third raceway 26 and the fourth raceway 23 are connected by balls, so that the limit block 25 can roll along the second cylinder body 21, effectively reducing the resistance when the limit block 25 moves, and the outer periphery of the limit block 25 is in contact with the second cylinder body 21 to be matched. The inner wall of the cylinder body 21 is a polygonal structure, which effectively prevents the limit block 25 from rotating. A third spline 27 is provided at one end of the limit block 25, and a fourth spline 33 is provided at one end of the spiral sleeve 31. The third spline 27 matches the fourth spline 33. The spiral sleeve 31 is connected to the limit block 25 through the third spline 27 and the fourth spline 33, so that when the spiral sleeve 31 is connected to the limit block 25 through the third spline 27 and the fourth spline 33, the rotation of the spiral sleeve 31 can be effectively limited.

[0041] Furthermore, in the emulsion axial motor of the present invention, the second cylinder body 21 is an annular cylinder, the interior of the second cylinder body 21 is arranged in a C shape, the interior of the second cylinder body 21 is matched with the annular cylinder core 24, the middle part of the second cylinder body 21 is matched with the first cylinder body 11, and the second cylinder body 21 is sleeved with the first cylinder body 11, so that the first cylinder 1 and the second cylinder 2 are integrated into one, effectively reducing the occupied space.

[0042] Furthermore, in the emulsion axial motor of the present invention, the bottom and side walls of the first cylinder body 11 and the second cylinder body 21 are both provided with liquid inlet and outlet holes 7 , thereby providing driving force to the valve core 12 and the annular cylinder core 24 .

[0043] The first cylinder body 11, the valve core 12, the second cylinder body 21 and the inner annular cylinder core 24 are all provided with an anti-rust layer to prevent rust and increase the service life.

[0044] Specifically, when the first cylinder body 11 discharges liquid through the liquid inlet and discharge holes 7 and the valve core 12 moves to the right, the annular cylinder core 24 in the second cylinder body 21 takes in liquid through the liquid inlet and discharge holes 7, driving the limit block 25 to move to the left together, so that the third spline 27 on the limit block 25 is connected to the fourth spline 33 on the spiral sleeve 31, thereby preventing the spiral sleeve 31 from rotating when the spiral inner core 34 rotates to the right; when the spiral inner core 34 moves to the right limit position, the annular cylinder core 24 in the second cylinder body 21 moves to the right after discharging liquid, and the limit block 25 connected thereto also moves to the right accordingly, so that the third spline 27 of the limit block 25 is disengaged from the fourth spline 33 on the spiral sleeve 31; when the first cylinder body 11 takes in liquid through the liquid inlet and discharge holes 7 and the valve core 12 moves to the left, the valve core 12 The limiter 5 is driven to move to the left. After moving a certain distance, the first spline 52 on the limiter 5 is connected with the second spline 35 on the spiral core 34 to lock the spiral core 34 to rotate, and at the same time, the spiral core 34 is driven to move to the left. During the process of the spiral core 34 moving to the left, the ball rolls between the first spiral groove and the second spiral groove, thereby driving the spiral sleeve 31 to rotate. When the valve core 12 moves to the leftmost position, the bottom of the annular cylinder core 24 is filled with liquid, driving the limit block 25 to move to the left end together. When it moves to a certain distance, the third spline 27 on the limit block 25 is connected with the fourth spline 33 on the spiral sleeve 31. At this time, the above movement is repeated, so that the axial force of the valve core 12 is converted into rotational force through the spiral transmission component 3, realizing the function of the rotary motor. When applied to the coal mine chain tightening motor, the output gear 6 can be installed on the radial outer side of the spiral sleeve 31, or it can be installed on the end surface to facilitate the tensioning gear.

[0045] In summary, compared with the prior art, the emulsion axial motor of the present invention has the following advantages and beneficial effects:

[0046] The present invention has a small size and can convert axial force into rotational force to achieve the function of a rotating motor, effectively reducing maintenance costs while effectively avoiding the risk of internal oil leakage. The overall structure is simple and compact, easy to process and manufacture, effectively reducing production costs and increasing service life.
