Problems solved by technology

[0002] The reducer is the most commonly used equipment in the transmission system. According to the difference in use, different requirements are put forward for the reducer: some require a larger transmission ratio, and some require a larger torque; In other words, to achieve a larger transmission ratio, it is necessary to increase the number of stages or the diameter of the gear, and to achieve a larger torque, it is necessary to increase the width and thickness of the gear. , the installation has brought a lot of inconvenience

Embodiment approach

[0017] figure 1 An embodiment of the digital gear reducer of the present invention is disclosed. The digital gear reducer of the present invention includes: a box body 1, two helical gears 2 with opposite rotation directions, an output shaft 3, a toggle device, an active rod 8, a sliding Bearing 5, crank link mechanism; two helical gears 2 are fixed on the same output shaft 3, and the output shaft 3 is axially fixed in the box body 1 through a plane bearing device or a one-way bearing device, and one end of the output shaft 3 is outward protrude from the shaft hole; the active rod 8 is slidingly matched with the inner wall of the box body 1 through the sliding bearing 5, and the sliding track of the active rod 8 is parallel to the output shaft 3; the crank linkage mechanism includes a crank 61, a connecting rod 62, and a crank 61 fixed in the box body 1, the two ends of the connecting rod 62 are hingedly connected with the crank 61 and the active rod 8 respectively; Fixedly c...

Embodiment approach 1

[0020] The transmission process of Embodiment 1 is as follows: first, power is applied to the crank 61, and the crank 61 rotates continuously, thereby driving the connecting rod 62 to perform a crank rocker movement, and then the connecting rod 62 drives the active rod 8 together with the toggle device along the inner wall of the box body 1 For reciprocating linear motion, the two ends of the lever 42 of the toggle device continuously and alternately push the two helical gears 2 to rotate, the helical gear 2 drives the output shaft 3 to rotate, and the output shaft 3 outputs the rotational torque. Wherein, when the driving end of the driving rod 42 is pushing the helical gear 2 to rotate, the passive end of the driving rod 42 just slides out from the tooth groove of the other helical gear 2, and points to the next tooth groove, and then the original driving rod 42 The passive end turns into the active end to push the corresponding helical gear 2 to rotate. Since the slot width ...

Embodiment approach 2

[0021] The difference between the transmission process of Embodiment 2 and the transmission process of Embodiment 1 is that in Embodiment 2, a cam 63 and a spring 7 are used, and the spring 7 always gives an upward force to the active rod 8, so that the upper surface of the active rod 8 is in contact with the cam. The surfaces are always in contact and pressed against each other; the cam 63 continuously moves in a circle under the drive of the external force, and then drives the active rod 8 to make a reciprocating linear movement along the inner wall of the box body 1 . Other than that, the sequence of torque transmission among other components is the same as that in the first embodiment.

Abstract

The invention relates to a transmission case of a speed reducer, in particular to a multi-gear speed reducer which is simple in structure and appropriate in size. The multi-gear speed reducer comprises a case body, two bevel gears opposite in directions, an output shaft, a shifting device, a driving bar member, a sliding bearing and a linear input mechanism, wherein the two bevel gears are fixed on the same output shaft which is fixed in the case body through a bearing device axially, and one end of the output shaft extends out of a shaft hole outwards. The driving rod member is in sliding match with the inner wall of the case body, and a sliding track of the driving rod member is parallel to the output shaft. The shifting device comprises a fixed rod and a shifting rod, wherein the middle of the shifting rod is fixedly connected with one end of the fixed rod, the other end of the fixed rod is fixedly connected with the driving rod member, and two ends of the shifting rod correspond to tooth grooves of the two bevel gears. When either end of the shifting rod moves along the corresponding tooth groove and pushes the gear to rotate, the other end of the shifting rod is released from the corresponding tooth groove and corresponds to the next tooth groove.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a transmission box of the speed reducer. Background technique [0002] The reducer is the most commonly used equipment in the transmission system.
