The utility model discloses a motor balancing block, which is characterized by comprising a first body and a second body. The first body comprises a first counterweight block and a first mounting block which are fixedly connected in a front-and-back arrangement, a first thread half hole penetrates through a middle part of a lower end face of the first body, the second body comprises a second counterweight block and a second mounting block which are fixedly connected in a front-and-back arrangement, a second thread half hole penetrates through a middle part of an upper end face of the second body, and the first thread half hole and the second thread half hole form a complete thread through hole when the first body and the second body are combined. The motor balancing block can prevent a balancing dead point phenomenon which occurs after a current balancing block is mounted, can be firmly mounted, and can realize a relatively large balancing radius, thus achieving the requirement for dynamic balancing of a motor rotor more easily.
Description
Technical field
The utility model belongs to motor bascule technical field, is specifically related to a kind of motor balancing block.
Background technology
The motor counterbalance effect has great impact to the quality of motor and vibration and noise control.Be used on the conventional balanced dish installing on the groove of balance weight and have circular hole, be used for the balance weight of packing into, can produce the balance dead point at tapping, and the equilibrium radius that can realize is little.
Summary of the invention
The purpose of this utility model provides a kind of motor balancing block, the balance dead point phenomenon that produces after avoiding existing balance weight to install, and install firmly, the equilibrium radius of realization is larger, more easily reaches the dynamically balanced requirement of rotor.
The technical scheme that the utility model adopts is, a kind of motor balancing block, it is characterized in that, comprise the first noumenon and the second body, the first balancing weight and the first mounting blocks that are fixedly connected with before and after the first noumenon comprises, connect at the middle part of the lower surface of the first noumenon and to have the first screw thread half hole, the second balancing weight and the second mounting blocks that are fixedly connected with before and after the second body comprises, connect at the middle part of the upper surface of the second body and to have the second screw thread half hole, the first screw thread half hole and the second screw thread half hole form a complete tapped through hole when the first noumenon and the second ontology merging.
The first mounting blocks and the second mounting blocks are the right-angled trapezium block structure, and both form an isosceles trapezoid block structure when the first noumenon and the second ontology merging.
The first mounting blocks and the second mounting blocks outer end are provided with chamfering.
The first balancing weight and the second balancing weight are the wedge structure, and both form a plane wedge structure when the first noumenon and the second ontology merging.
The beneficial effect of the utility model motor balancing block is: the utility model adopts split-type structural, on the balancing frame of the rotor of its installation, do not need out installing hole, therefore the shape of each section of compensating groove on the balancing frame is consistent and continuous, can not cause balance dead point phenomenon.In addition, owing to the utlity model has the first configuration block and the second balancing weight, therefore compare with existing motor balancing block, under the condition that guarantees identical counterbalance effect, the quantity that finally need to install is less, in other words, the utlity model has larger equilibrium radius.

Wherein, 1. the first noumenon, 1-1. the first balancing weight, 1-2. the first mounting blocks, 1-3. the first screw thread half hole, 2. the second body, 2-1. the second balancing weight, 2-2. the second mounting blocks, 2-3. the second screw thread half hole, 3. balancing frame, 4. lock-screw, 5. nut, 6. wedge-shaped body.
Embodiment
Such as Fig. 8 with Figure 9 shows that existing motor balancing block, centered by have the wedge-shaped body 1 of tapped through hole.When mounted, in the compensating groove on the balancing frame that puts it into rotor, must open a diameter greater than the installing hole of wedge-shaped body 1 maximum outline at compensating groove, again wedge-shaped body 1 is put into from installing hole, after sliding into suitable position along compensating groove, fix and put with lock-screw and be welded on the balancing frame.But when amount of unbalance was created in the installing hole position, what balance weight can't safety and stability was fixing, had therefore produced the balance dead point.
Be the utility model motor balancing block as depicted in figs. 1 and 2, comprise the first noumenon 1 and the second body 2.Extremely shown in Figure 6 in conjunction with Fig. 3, the the first balancing weight 1-1 and the first mounting blocks 1-2 that are fixedly connected with before and after the first noumenon 1 comprises, connect at the middle part of the lower surface of the first noumenon 1 and to have the first screw thread half hole 1-3, the first mounting blocks 1-2 is the right-angled trapezium block structure, the first mounting blocks 1-2 outer end is provided with chamfering, and the first balancing weight 1-1 is the wedge structure.The the second balancing weight 2-1 and the second mounting blocks 2-2 that are fixedly connected with before and after the second body 2 comprises, connect at the middle part of the upper surface of the second body 2 and to have the second screw thread half hole 2-3, the second mounting blocks 2-2 is the right-angled trapezium block structure, the second mounting blocks 2-2 outer end is provided with chamfering, and the second balancing weight 2-1 is the wedge structure.When the first noumenon 1 and 2 merging of the second body, the first screw thread half hole 1-3 and the second screw thread half hole 2-3 form a complete tapped through hole, the first mounting blocks 1-2 and the second mounting blocks 2-2 form an isosceles trapezoid block structure, and the first balancing weight 1-1 and the second balancing weight 2-1 form a plane wedge structure.
The utility model adopts split-type structural, and guarantees not destroy screw thread.When mounted, only need to put respectively the first noumenon 1 and the second body 2 compensating groove of balancing frame 3 into and slide into the relevant position of requirement, the first noumenon 1 and the second body 2 are merged alignment, at this moment, the first mounting blocks 1-2 and the second mounting blocks 2-2 form an isosceles trapezoid block structure also and the shape of mounting groove adapts, the first balancing weight 1-1 and the second balancing weight 2-1 form a plane wedge structure and are stuck in the surface of balancing frame 3, and the first screw thread half hole 1-3 and the second screw thread half hole 2-3 form a complete tapped through hole.By lock-screw 4 and this tapped through hole be fixed the first noumenon 1 and the second body 2, at lock-screw 4 nut 5 is set again and further plays the effect that is locked, can also be aided with spot welding.The utility model does not need out installing hole on the balancing frame 3 of its installation, so the shape of each section of compensating groove on the balancing frame 3 is consistent and continuously, can not cause balance dead point phenomenon.
In addition, because the first balancing weight 1-1 and the second balancing weight 2-1 form a plane wedge structure and are stuck in the surface of balancing frame 3, compared with prior art, balance weight of the present utility model has expanded to the outer space of compensating groove, the monolithic volume increases, so that monomer balance weight weight becomes multiple to increase, center of gravity departs from outside balancing frame 3 centers of circle, so that equilibrium radius more easily reaches the requirement of rotor dynamic balancing than the large 10～20mm of traditional balance mode.
