Abstract
The utility model relates to a component of a machine tool plant, particularly to an R-shaped sliding screw nut for driving a screw rod. The utility model is characterized in that the cross section of inner screw-thread teeth of a nut body forms an R shape. Therefore, the utility model has the advantages of high driving accuracy, large carrying capacity, good sliding performance, low failure rate, long service life, easy processing and low cost.
Description
Technical field: the utility model belongs to parts of machine tool, is specifically related to the R type slip screw that a kind of lead screw transmission is used.
Background technique: at present, be applied to the lead screw pair on the lathe, transmission accuracy is than higher have two kinds, and a kind of is ball screw pair, has that bearing capacity is little, impact resistance is poor, the high shortcoming of short rate of fault in working life; Another kind is the acme thread lead screw pair, has the shortcoming of easy wedging.
Summary of the invention: goal of the invention of the present utility model provides a kind of transmission accuracy height, bearing capacity is big, sliding good, rate of fault is low, the R type slip screw of long service life.
The technical solution of the utility model is: a kind of R type slip screw is characterized in that the internal thread tooth cross section of nut body is the R type.
Owing to adopt technique scheme, the tooth cross section of screw internal thread is the R type, and is little with alveolus matching gap on the screw mandrel, area of contact is big, thus have the transmission accuracy height, bearing capacity is big, sliding good, rate of fault is low, long service life, the easily low advantage of processing cost.
Description of drawings: come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings.A kind of R type slip screw, internal thread tooth 2 cross sections of nut body 1 are the R type.
Claims (1)
1, a kind of R type slip screw is characterized in that: internal thread tooth (2) cross section of nut body (1) is the R type.
