Abstract
The utility model relates to a direct-drive oil-free sewing machine feed lifting device which comprises a feed lifting cam. A feed lifting crank is arranged at the outside of the feed lifting cam; and one ends of the feed lifting cam and the feed lifting crank are provided with end covers. The direct-drive oil-free sewing machine feed lifting device is characterized in that a single-row radial ball bearing is arranged between the feed lifting cam and the feed lifting crank; and a sealing cover is arranged in the single-row radial ball bearing. In the scheme, the single-row radial ball bearing is arranged between the feed lifting cam and the feed lifting crank, grease of the single-row radial ball bearing adopts high temperature lubricating grease and is not easy to melt, and the sealing cover is arranged in the single-row radial ball bearing, thereby enabling the grease not to overflow, avoiding suture pollution and solving the loss caused by oil leak. The utility model has significant features.
Description
Technical field
The utility model relates to Sewing machines, and what relate to particularly that a kind of direct-driving type do not have an oily Sewing machines lifts the tooth device, belongs to the garment machinery field.
Background technology
That directly drives no oily Sewing machines lifts the tooth device, it is the chassis left direction that tooth lifting cam generally is installed in Sewing machines, because cam high speed rotating, needle bearing grease in the existing cam can be excessive because of sealing insecure reason, pollute suture, and cause bearing to lack lubricatedly to cause damage of components, cause machine normally to use, bring loss because of grease is excessive to enterprise.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of employing sealed bearing to be provided, make bearing grease not excessive, avoids suture to pollute, and parts do not have the no oily Sewing machines of directly driving of damage and lift the tooth device.
The utility model directly drives the technical scheme that no oily Sewing machines lifts the tooth device: comprise tooth lifting cam, tooth lifting cam is installed feed lifting rock shaft crank outward, one end of tooth lifting cam and feed lifting rock shaft crank is equipped with end cap, it is characterized in that between described tooth lifting cam and the feed lifting rock shaft crank single-row radial ball bearing being installed, be equipped with seal cover in the single-row radial ball bearing.
Of the present utility modelly directly drive no oily Sewing machines and lift the tooth device, between described tooth lifting cam and feed lifting rock shaft crank, single-row radial ball bearing is installed, the grease of single-row radial ball bearing adopts high-temperature lubricating grease, be difficult for melting, and in single-row radial ball bearing, be equipped with seal cover, grease can not overflowed, avoid suture to pollute, thereby solved the loss that produces because of leakage of oil, had outstanding feature.
Description of drawings
Fig. 1 is that the utility model directly drives no oily Sewing machines and lifts tooth apparatus structure schematic diagram.
The specific embodiment
The utility model relates to and a kind ofly directly drives no oily Sewing machines and lift the tooth device, as shown in Figure 1, comprise tooth lifting cam 1, the tooth lifting cam 1 outer feed lifting rock shaft crank 2 of installing, tooth lifting cam 1 is equipped with end cap 3 with an end of feed lifting rock shaft crank 2, it is characterized in that single-row radial ball bearing 4 is installed between described tooth lifting cam 1 and the feed lifting rock shaft crank 2, be equipped with seal cover 5 in the single-row radial ball bearing 4.This programme is installed single-row centripetal ball journal 4 and is held between described tooth lifting cam 1 and feed lifting rock shaft crank 2, the grease of single-row radial ball bearing 4 adopts high-temperature lubricating grease, be difficult for melting, and in single-row radial ball bearing 3, be equipped with seal cover 5, grease can not overflowed, avoid suture to pollute, thereby solved the loss that produces because of leakage of oil, have outstanding feature.
