目前市场上的混凝土搅拌车需求量很大，购买的人也很多，其制作工艺也是非常的，那么关于小型混凝土自动搅拌车的轴承制作工艺你了解多少呢？

At present, there is a large demand for concrete mixer trucks in the market, and there are many buyers. Their production process is also very professional. So, how much do you know about the bearing production process of small concrete automatic mixer trucks?

搅拌车轴承的设计和制作工艺，必须要考虑到轴承的热平衡以控制温升，因为轴承在摩擦状态下工作，由于润滑液体内部摩擦而造成功耗，转化成热量后引起轴承温升，润滑油粘度降低、间隙会改变，会使轴承的巴氏合金软化，严重时产生“烧瓦抱轴”的事故。

The design and manufacturing process of mixer truck bearings must take into account the thermal balance of the bearings to control temperature rise, as the bearings work in a frictional state. Due to internal friction of the lubricating fluid, power consumption is generated, which is converted into heat and causes bearing temperature rise. The viscosity of the lubricating oil decreases, and the clearance changes, which can soften the Babbitt alloy of the bearings, and in severe cases, it can lead to accidents such as "burning the bearings and holding the shafts".

搅拌车提高轴承的维修和装配质量，保证轴承背面光滑点，定位凸点完整无损，自身的弹开量为0.5-1.5mm，这保证装配后轴瓦借助自身弹力与轴承座孔贴合紧密，转载轴承座内的上下两片轴瓦的每端均应高出轴承座平面30-50微米，高出量可保证按规定扭矩拧紧轴承盖螺栓后轴承与轴承座紧密配合，产生足够的摩擦自锁力。

The mixer truck improves the maintenance and assembly quality of bearings, ensuring that the back of the bearings is smooth and spotless, and the positioning protrusions are intact and undamaged. The self opening amount is 0.5-1.5mm, which ensures that the bearing shells are tightly attached to the bearing seat hole with their own elasticity after assembly. Each end of the upper and lower bearing shells in the transfer bearing seat should be 30-50 microns higher than the bearing seat plane, and the excess amount can ensure that the bearing cover bolts are tightened according to the specified torque, and the bearing and the bearing seat are closely matched, Generate sufficient frictional self-locking force.

轴承不致松动，散热效果好，防止轴承烧蚀和磨损，轴承的工作面不能用刮配法达到75%-85%接触印痕做衡量标准，应在不刮削时就使轴承和轴径的配合间隙达到要求。

The bearing does not loosen, has good heat dissipation effect, and prevents bearing erosion and wear. The working surface of the bearing cannot be measured by scraping to reach 75% -85% contact marks. The clearance between the bearing and the shaft diameter should meet the requirements without scraping.

小型混凝土自动搅拌车的使用除了对发动机、底盘等部位进行维护外，还必须做好对混凝土搅拌罐及进出料口的清洗，在每次运送混凝土结束后，要及时的清洗搅拌罐及进出料斗，这样可有效减少混凝土粘附罐体的现象，可降低车辆的保养工作强度。

In addition to maintaining the engine, chassis, and other parts, the use of small concrete automatic mixer trucks also requires proper cleaning of the concrete mixing tank and inlet and outlet. After each delivery of concrete, the mixing tank and inlet and outlet hoppers should be cleaned in a timely manner, which can effectively reduce the phenomenon of concrete adhering to the tank and reduce the maintenance intensity of the vehicle.

错开生产高峰，及时的对进料斗、下料口及卸料槽进行局部的补焊，加装罐体修止口，以减少设备在进出料过程中造成的漏浆漏料现象，在保证设备完好率的基础上大限度的保证设备的整洁。

Stagger production peaks, timely carry out local welding on the feeding hopper, discharge port, and discharge groove, and install tank body repair ports to reduce slurry and material leakage caused by the equipment during the feeding and discharging process. On the basis of ensuring the equipment's integrity rate, maximize the cleanliness of the equipment.
