Abstract

The utility model relates to a dry -type wire reel brake equipment for rectifier transformer for variable frequency speed governing(VFSG), include: large disc, bearing, the steel ring that compresses tightly the bearing and carousel, large disc are wire -wound disc, and the axle of bearing passes large disc, and the steel ring that compresses tightly the bearing includes the carousel setting stick and change disc shaft for the steel ring of arc both ends for fixing the ear, carousel that commentaries on classics disc shaft lower extreme is the screw thread section for the centre, the steel ring cover that compresses tightly the bearing is on the outer lane of bearing, and the fixed ear that compresses tightly the steel ring one end of bearing is rotationally fixed on the support, and the fixed ear pressure of the other end is in the screw thread section of the commentaries on classics disc shaft's of carousel lower extreme, and the bolt section of changeing disc shaft can rise in the fixed ear of steel ring or descend. The utility model discloses it mainly acts on is the dynamics that can adjust the wire tensioning at any time, guarantee that the power on the whole wire when the coiling of whole coil is even, fewer and feweri and lead to the more and more loose condition of wire when the coiling along with the wire on the drum before having avoided.

Description

A kind of frequency control dry-type rectifier transformer wire spool brake gear

Technical field

The utility model relates to a kind of brake gear, is specifically related to a kind of dynamics that can regulate wire tensioning at any time, ensures the uniform frequency control dry-type rectifier transformer of the power when coiling on the whole wire wire spool brake gear of whole coil.

Background technology

Wire spool is being mainly used in coil winding, in actual winding process, needs have certain tensile force and more stable coiling speed to guarantee the elasticity of coiling to cable.Now common coiling drum along with the wire on drum fewer and feweri, cause wire more and more loose.

Utility model content

For the problems referred to above, main purpose of the present utility model is to provide a kind of dynamics that can regulate wire tensioning at any time, ensures the uniform frequency control dry-type rectifier transformer of the power when coiling on the whole wire wire spool brake gear of whole coil.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of frequency control dry-type rectifier transformer wire spool brake gear, described brake gear comprises: the steel ring of big disk, bearing, compression bearing and rotating disk, whole brake gear is fixed on support, big disk is the disk of coiling, the axle of bearing is through big disk, compress the steel ring of bearing be middle for arc two ends be the steel ring of fixing ear, rotating disk comprises rotating disk setting stick and rotating disk bar, and rotating disk bar lower end is thread segment; Compress the steel ring sleeve of bearing on the outer ring of bearing, the fixing ear compressing steel ring one end of bearing is rotatably mounted on support, the fixing ear of the other end is pressed in the thread segment of the lower end of the rotating disk bar of rotating disk, and the bolt section of rotating disk bar can rise or decline in the fixing ear of steel ring.

In specific embodiment of the present utility model, the length range of the thread segment of described rotating disk bar lower end is 5-10cm.

Positive progressive effect of the present utility model is: the frequency control dry-type rectifier transformer wire spool brake gear that the utility model provides has the following advantages: this brake gear that the utility model provides adds an increased device at original coiling drum, its Main Function is the dynamics that can regulate wire tensioning at any time, the power when coiling on whole wire ensureing whole coil is uniform, causes the situation of when coiling wire more and more pine before avoiding along with the wire on drum is fewer and feweri.

Embodiment

The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the front view of overall structure schematic diagram of the present utility model, Fig. 2 is the right view of overall structure schematic diagram of the present utility model, Fig. 3 is partial perspective view of the present utility model, as Figure 1-3, the utility model comprises: big disk 1, bearing 2, compress steel ring 3 and the rotating disk 4 of bearing, whole brake gear is fixed on support 5, big disk 1 is the disk of coiling, the axle of bearing 2 is through big disk 1, compressing the steel ring 3 of bearing be centre for arc two ends are the steel ring of fixing ear, rotating disk 4 comprises rotating disk setting stick 401 and rotating disk bar 402, rotating disk bar 402 lower end is thread segment, the steel ring 3 compressing bearing is enclosed within the outer ring of bearing 2, the fixing ear compressing steel ring 3 one end of bearing is rotatably mounted on support 5, the fixing ear of the other end is pressed in the thread segment of the lower end of the rotating disk bar 402 of rotating disk 4, and the bolt section of rotating disk bar 402 can rise or decline in the fixing ear of steel ring 3.The length range of the thread segment of rotating disk bar 402 lower end is 5-10cm.

When using the utility model, first opened by the steel ring compressing bearing, then drum is put well on bobbin loader, is bolted together in the hole on the big disk of brake gear and drum.After fixing drum, steel ring is closed, rotate rotating disk bolt, choose the frictional force suitable with bearing according to the actual needs, thus ensure the wire between coil winding machine and drum has a suitable tension force, ensure the tight of line cake coiling.

This brake gear that the utility model provides adds an increased device at original coiling drum, its Main Function is the dynamics that can regulate wire tensioning at any time, the power when coiling on whole wire ensureing whole coil is uniform, causes the situation of when coiling wire more and more pine before avoiding along with the wire on drum is fewer and feweri.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
