Ball retainer type ball screw
SBN, SBK, SDA, HBN and SBKH type use the ball retainer, which can eliminate the collision and friction between the steel balls and improve the retention of grease, thus achieving low noise, low torque variation And long-term operation without maintenance. In addition, the ideal ball circulation structure, the strength of the circulation and ball retainer increases, so that the ball screw has excellent high speed.
Ball retainer effect:
1. Low noise, good sound quality: The use of ball retainer eliminates the collision noise between the steel balls. In addition, because the balls are arranged in a tangential direction, the collision noise caused by the ball circulation is also eliminated.
2. Long-term operation and maintenance-free: the friction between the balls has been eliminated, and due to the grease bag is provided to maintain the grease, so long-term operation and maintenance-free (that is, no grease in the long term).
3. Smooth movement: The use of the ball retainer eliminates friction between the balls and reduces the rate of torque variation, resulting in a smooth rotational movement.
4. Low noise: Since the balls in the ball retainer THK ball screw
do not collide with each other, they do not generate metal noise and thus achieve low noise level.
5. Long-term operation and maintenance-free: high-speed, load durability, due to the support of high-speed ball circulation and ball retainer effect, both in terms of high speed and load durability showed excellent performance.
A.SBN type with a circular structure of the ball arranged in the tangential direction, increasing the strength of the cycle, so that the DN value of 130,000.
B.SBK type due to the use of pre-offset the way, the method of moving the ball screw nut two rows of grooves, so the structure is quite compact.
No pre-press type:
A.SDA type This kind of lead screw adopts the newly developed end cap and R member, obtained the ideal steel ball circulation structure, realized the device is greatly compacted.
B.HBN type Due to the optimized design for high load, this type of ball screw
to achieve the rated load is more than 2 times the traditional products.
C.SBKH type This kind of lead screw has realized the high carrying capacity and can be used at a high speed (maximum 92m / min).
