Description
Technical Field
The utility model relates to the technical field of brakes, in particular to a brake with a mute rubber ring.
Background
The operation principle of the traditional servo brake is that when the brake is electrified, a coil generates a magnetic field to attract an armature plate to a coil housing mounting surface, an air gap originally set between the housing and the armature plate disappears along with axial movement of the armature plate, and gaps are correspondingly generated between the armature plate and a brake block as well as between the brake block and a bottom plate. The inner tooth skeleton of the brake block is made of aluminum or iron material, and the gear shaft sleeve is made of iron material. The motor shaft drives the shaft sleeve to rotate, the shaft sleeve drives the brake block to rotate, and the axial fit between the inner teeth of the brake block and the gear shaft sleeve needs to be kept at a certain smoothness. If the fit between the shaft sleeve and the brake pad is too loose, metal impact can be caused between the inner teeth of the brake pad and the outer teeth of the gear shaft sleeve because of gaps. If the fit between the shaft sleeve and the brake pad is too tight, the brake pad cannot be separated from the bottom plate, and the brake pad is in friction interference with the bottom plate.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following description will be made in detail with reference to the technical solutions in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments.
The inner tooth skeleton of the brake block is made of aluminum or iron material, and the gear shaft sleeve is made of iron material. The motor shaft drives the shaft sleeve to rotate, and the shaft sleeve drives the brake pad to rotate. The existing gear shaft sleeve and the brake pad are directly contacted with the inner teeth of the brake pad through the outer teeth of the gear shaft sleeve. The gear shaft sleeve and the brake pad are both made of metal. If the fit between the gear shaft sleeve and the brake pad is too loose, collision can occur between the gear shaft sleeve and the brake pad when the motor shaft drives the gear shaft sleeve to rotate, and noise is generated. If the gear shaft sleeve is in over-tight fit with the brake pad, the brake pad cannot move along the axial direction of the gear shaft sleeve, so that the brake pad is firmly extruded onto the bottom plate, and the brake pad is in frictional interference with the bottom plate.
In view of the above-mentioned technical problems, this embodiment provides a brake with a mute rubber ring, referring to fig. 1, the brake with a mute rubber ring includes a coil body housing 1, a fixing dish screw 6 is mounted at an edge of the coil body housing 1 along an axial direction, a bottom plate 5 is screwed to one end of the fixing dish screw 6 protruding to an outside of the coil body housing 1, and the bottom plate 5 and an end face of the coil body housing 1 remain parallel.
The adjustable sleeve 4 is coaxially connected to the outside of the fixed dish-shaped screw 6 by threads, one end of the adjustable sleeve 4 abuts against the end face of the bottom plate 5, and the other end is connected to the coil body housing 1. The armature plate 3 slides along the adjustable sleeve 4 in the axial gap between the coil body housing 1 and the base plate 5.
The gear sleeve 9 is coaxially mounted on the end of the motor shaft and extends coaxially into the armature plate 3 in the axial direction of the coil body housing 1. The brake pad 7 is disposed outside the gear sleeve 9 and is slidable in the axial direction of the gear sleeve 9. In the axial direction of the coil body housing 1, the brake pad 7 is arranged between the armature plate 3 and the base plate 5.
A plurality of annular rubber grooves are formed in the outer wall of the gear shaft sleeve 9, extend along the circumferential direction of the gear shaft sleeve 9, and are concentric with the gear shaft sleeve 9.
In this embodiment, two rubber grooves are used, and the two rubber grooves are distributed along the axial direction of the gear shaft sleeve 9 and are respectively located near two ends of the gear shaft sleeve 9. An O-shaped rubber ring 10 is adhered in the rubber groove. When the brake block 7 is arranged outside the gear shaft sleeve 9, the O-shaped rubber ring is pressed by the brake block 7.
The O-shaped rubber ring is made of rubber materials, has large friction coefficient, and is in interference fit, so that the O-shaped rubber ring can effectively and fixedly install a brake pad, and stable installation of the brake pad 7 and the gear shaft sleeve 9 is realized. The occurrence of metal impact between the brake pad 7 and the gear sleeve 9 during rotation is avoided, and noise generated by the metal impact is avoided.
The O-shaped rubber ring is made of rubber materials, and has high toughness and elasticity. When the armature plate 3 presses the brake pad 7 in the axial direction, the brake pad 7 may move relatively in the axial direction to abut against the bottom plate 5, thereby pressing the bottom plate 5.
In contrast, when the armature plate 3 is separated from the brake pad under the action of electromagnetic force, the rubber ring can drive the brake pad 7 to move along the axial direction after being reset along the axial direction, so that a certain axial gap is kept between the brake pad and the bottom plate, and the brake pad and the bottom plate are prevented from being locked or friction interference is avoided along the end face of the bottom plate.
In another embodiment, referring to fig. 2 and 6, internal teeth (i.e., an inner ring of the brake pad 7) are arranged on a side of the brake pad 7 that cooperates with the gear sleeve 9, a plurality of the internal teeth being distributed along a circumferential direction of the brake pad 7, and a single of the internal teeth extending along an axial direction of the brake pad 7. External teeth are arranged on the side surface of the gear sleeve 9 matched with the brake pad 7 (namely, the outer ring of the gear sleeve 9), and a plurality of external teeth are distributed along the circumferential direction of the gear sleeve 9. The individual external teeth extend in the axial direction of the gear sleeve 9. The brake pad 7 and the gear sleeve 9 are engaged by the inter-engagement of the internal teeth and the external teeth.
When the armature plate 3 moves in the axial direction of the coil body housing 1 and is disengaged from the brake pad 7 by electromagnetic force. The pressing force of the armature plate 3 to the brake pad 7 along the axial direction of the coil body housing 1 disappears, at this time, the brake pad 7 moves along the axial direction of the coil body housing 1 under the elastic restoring action of the O-shaped rubber ring, in this process, the internal teeth move along the tooth grooves between the two external teeth, and the brake pad 7 is stably separated from the bottom plate 5 along the axial direction under the cooperation of the internal teeth and the external teeth.
In another embodiment, referring to fig. 3, 4 and 5, the gear sleeve 9 is not provided with an O-ring rubber. In the present utility model, when the brake pad 7 is mounted to the outside of the gear sleeve 9, the internal teeth of the brake pad 7 extend into the tooth spaces between two adjacent external teeth of the gear sleeve 9. Because the diameter of the outer ring of the O-shaped rubber ring is larger than the diameter of the top circle of the inner teeth of the brake block 7, the inner teeth of the brake block 7 are extruded to the outer ring of the O-shaped rubber ring along the radial direction of the O-shaped rubber ring, so that interference fit between the O-shaped rubber ring and the brake block is realized, and the brake block is firmly fixed outside the gear shaft sleeve 9.
In another embodiment, referring to fig. 1, copper wires are wound in the inner cavity of the coil body case 1, and the copper wires protrude from the copper wire outlet groove 8 to the outside of the coil body case 1. When the copper wire is energized, an electromagnetic force is generated, which drives the armature plate 3 to move in the axial direction of the coil body case 1.
A rubber ring 2 is embedded on one side of the coil body shell 1 opposite to the bottom plate 5. After the armature plate 3 gradually approaches and contacts the end face of the coil body housing 1 under the adsorption of electromagnetic force, the armature plate 3 abuts against the end face of the rubber ring 2. The rubber ring 2 is made of rubber materials, and when the armature plate 3 contacts the end face of the coil body shell 1, the rubber ring 2 plays a role in supporting and buffering, so that the armature plate 3 is prevented from being hard impacted on the coil body shell 1. Meanwhile, when the electromagnetic force is eliminated after the copper wire is powered off, the rubber ring 2 pushes the armature plate 3 to move and press onto the brake pad 7.
Standard parts used in the utility model can be purchased from the market, special-shaped parts can be customized according to the description of the specification and the drawings, the specific connection modes of all parts adopt conventional means such as mature supporting blocks, rivets, welding and the like in the prior art, the machinery, the parts and the equipment adopt conventional types in the prior art, and the circuit connection adopts conventional connection modes in the prior art, so that details are not described in detail in the specification, and the technical field which is not known in the prior art is adopted.
