Description
The new shape of this practicality relates to electric motor starting energy-saving safety field
Routinely, when machinery runs well for the motor that starts safe adapted all exceeds 10 of power demand, also need increase other distribution facility in addition could move in clean boot, people are in production practices, power consumption is big during for solution equipment electric motor starting, equipment is hit, the gear rapid wear, energy-conservation safety starting devices such as friction disk type magnetic clutch and compensator have been used in design, but all because of problems such as their power consumption itself and technology, prices, on the occasion equipment that varies in size, use can't be easy the requirement of satisfying the user.
The purpose of this utility model be design a kind of simple in structure, part is few, cost is low, easy-maintaining, in electric-motor-driving, should make motor be similar to No Load Start, motor pulley drives the machinery time-delay soft start through belt, realize that reduction inrush current, saving electric energy, protection motor, reduction motor start the impact to electrical network at full capacity, reduce distribution facility; Avoid machinery in starting impact, to cause the damage of part, prolong life of equipment, guarantee safety in production.
Realize the technical solution of the utility model: the drive sleeve that matches with motor transmission shaft is enclosed drive sleeve and is shaped on the circle shoulder in a nearly end, on the side of shoulder the soft start disk is housed, and the outer cutting of soft start disk is bent into herringbone, oar shape.The belt pulley external diameter is made of big or small two-part, on big external diameter termination, inwardly make the shell shape and form power transmission medium cavity half, be sleeved on the drive sleeve, between drive sleeve and the belt pulley bearing is housed with half driving medium cavity with the belt pulley of half power transmission medium cavity.Half power transmission medium cavity in addition with the corresponding cooperation of half power transmission medium cavity of belt pulley termination, the center is shaped on the hole that adapts with drive sleeve and by screw two half power transmission medium cavitys is fitted together, form the power transmission media cavity, the soft start disk of adorning on the drive sleeve falls into the power transmission media cavity, put a certain amount of power transmission medium in the power transmission media cavity, Sealing is equipped with at the position that is rotatably assorted, and forms the utility model.
Concrete structure of the present utility model is provided by the following examples and accompanying drawing thereof.
Fig. 1 is that a kind of New-type electric machine starts the clutch configuration schematic representation.
Fig. 2 is that a kind of New-type electric machine starts the another kind of structural representation of clutch.
Describing a kind of New-type electric machine in detail below in conjunction with Fig. 1, Fig. 2 starts the clutch specific structural details and uses working condition.
With reference to Fig. 1, the drive sleeve that matches with motor transmission shaft (1) is enclosed drive sleeve and is shaped on circle shoulder (11) at a proximal head place, circle shoulder (11) is gone up uniform porose, on the side of circle shoulder (11) soft start disk (2) is housed, and the outer cutting of soft start disk (2) is bent into herringbone, oar shape.The external diameter of belt pulley (4) has big or small two-part to constitute, on big external diameter termination, inwardly make the shell shape and form half power transmission medium cavity (5), belt pulley (4) with half power transmission medium cavity (5) is sleeved on the drive sleeve (1), between drive sleeve (1) and the belt pulley (4) with half power transmission medium cavity (5) bearing (3) is housed.With the center of half power transmission medium cavity (6) in addition of the corresponding cooperation of half power transmission medium cavity (5) of belt pulley (4) termination one hole of directly matching with drive sleeve (1) end is arranged, two half power transmission medium cavity (5), (6) are connected by screw, form power transmission media cavity (56), the soft start disk (2) that drive sleeve (1) goes up dress falls into power transmission media cavity (56), and a certain amount of power transmission medium iron sand (7) is housed in the power transmission media cavity (56).Sealing (8) is equipped with at the position that is rotatably assorted.
With reference to Fig. 2: the radial dimension of heavy-duty motor, power transmission medium cavity (5), (6) will design and become big, make with half power transmission medium cavity (5) that belt pulley (4) is connected as a single entity together, technology difficulty is big, the cost of production height, half power transmission medium cavity (5) that belt pulley (4) can be connected as a single entity with it is made respectively, is connected as a single entity by screw (9) during assembling.
When a kind of New-type electric machine startup clutch is used in equipment operation, its working principle: according to the size of equipment operation power demand, apolegamy motor and electric motor starting clutch, the drive sleeve (1) of electric motor starting clutch is packed on the motor transmission shaft, open motor, soft start disk (2) together with drive sleeve (1) rotates with motor, realize the approximate No Load Start of motor, in approximate No Load Start rotation, soft start disk (2) is taken off the power transmission medium iron sand (7) in the power transmission media cavity (56), the belt pulley (4) that is connected with power transmission medium cavity is slowly started, realized belt pulley (4) through belt together with the equipment time-delay soft start.Be connected with the belt pulley (4) of power transmission medium cavity is taken off power transmission medium iron sand (7) rotating speed along with soft start disk (2) raising, power transmission medium iron sand (7) is in power transmission media cavity (56) internal cause action of centrifugal force, power transmission medium iron sand (7) is distributed on the internal diameter of power transmission media cavity (56), making power transmission medium iron sand (7) and soft start disk (2) outer form static(al) combines, realize the same synchronizing motors of belt pulley, satisfy the equipment necessary requirement.This electric motor starting clutch has realized that power motor is similar to No Load Start, motor driven equipment time-delay soft start.
Advantage of the present utility model: 1. need not set up outside electrical matching when this startup clutch is worked Facility, part are few, simple in structure, and cost is low, are convenient to maintenance; 2. realized that motor is approximate No Load Start has been exempted the adapted of equipment overpower motor, has realized economize on electricity; 3. machinery is established For having realized delayed startup, reduced mechanically activated impulsive force, protected the running device gear to exist Impact failure during startup has prolonged service life of equipment, has guaranteed equipment safety operation.
