Embodiment 1
[0038] The method for preventing the illegal start of the output shaft for the maintenance of the grinding wheel device includes the following steps:
[0039] S1. A friction assembly is installed on the end surface where the motor 1 of the grinder passes through the transmission shaft 2. The friction assembly includes a bottom plate 8 sleeved on the transmission shaft 2 and fixed on the casing of the motor 1 and along the diameter of the transmission shaft 2. To the friction unit slidably installed on the bottom plate 8, the friction unit includes a friction piece slidably installed on the bottom plate 8 and a spring 9 connected to the friction piece and the bottom plate 8 at both ends, the axis of the spring 9 is parallel to the friction piece The sliding direction of the friction member can be brought into contact with the outer circumferential surface of the transmission shaft 2 under the deformation of the spring 9;
[0040] There are two friction units, which are symmetri...
Embodiment 2
[0050] This embodiment is an implementation description of the linear drive mechanism in Embodiment 1.
[0051] Such as figure 2 As shown, the linear drive mechanism includes an internally threaded cylinder 10 radially inserted on the support sleeve 6 and a screw 11, a bearing 12 and a moving rod 13 connected coaxially in sequence, as shown in Image 6 As shown, the screw 11 is located on the side of the internally threaded cylinder 10 away from the transmission shaft 2, one end of which is inserted into the internally threaded cylinder 10 and screwed with the internally threaded cylinder 10, and the moving rod 13 is located on the internally threaded cylinder 10 close to the transmission shaft 2, one end of which is connected to the insert block 14, and the other end is inserted into the inner hole of the internally threaded barrel 10, and is connected with the screw rod 11 through the bearing 12, and the inner and outer rings of the bearing 12 are respectively connected wit...
Embodiment 3
[0058] This embodiment is a further description of the sliding fit between the friction member and the bottom plate 8 .
[0059] Such as figure 1 with figure 2 As shown, a chute B17 is provided on the bottom plate 8, the axis of the chute B17 is perpendicular to the axis of the transmission shaft 2, and the side of the friction member close to the bottom plate 8 protrudes outward to form a slider 18, so The slider 18 is inserted into the sliding groove B17 and is slidably fitted therewith.
[0060] Further, the end of the chute B17 away from the transmission shaft 2 is a closed end, the spring 9 is located in the chute B17, and is located on the side of the slider 18 away from the transmission shaft 2, and its two ends are connected to the slider 18 respectively. And one end away from the transmission shaft 2 on the chute B17 is connected.
[0061] Correspondingly, when the spring is located on the side of the slider close to the transmission shaft 2 , the tension deformat...
